Newton’s Laws of Motion
Newton’s Laws of Motion introduce students to the three famous laws that explain how motion, force, acceleration, actions, etc. work on objects. Students will learn what each law is and be able to explain them. They will also be able to provide examples that represent each law.
The “Options for Lesson” section provides several additional suggestions of things to do for the lesson. One suggestion is to group students and assign them a specific law. They can make that law the focus of their presentations. You could also have them observe examples in their neighborhoods or at home of the laws.
Description
Additional information, what our newton’s laws of motion lesson plan includes.
Lesson Objectives and Overview: Newton’s Laws of Motion teaches students the three laws that Sir Isaac Newton realized in the 17th century. Students will discover what each law is and will be able to provide examples of each. By the end of the lesson, they should be able to recognize examples of each law as they observe them happening. This lesson is for students in 5th grade and 6th grade.
Classroom Procedure
Every lesson plan provides you with a classroom procedure page that outlines a step-by-step guide to follow. You do not have to follow the guide exactly. The guide helps you organize the lesson and details when to hand out worksheets. It also lists information in the yellow box that you might find useful. You will find the lesson objectives, state standards, and number of class sessions the lesson should take to complete in this area. In addition, it describes the supplies you will need as well as what and how you need to prepare beforehand. For this lesson, you will need a variety of supplies, such as marbles, balls of different sizes, rubber bands, small toys, and so on. Read the activity worksheet to figure out what other materials you might want to use.
Options for Lesson
The “Options for Lesson” section lists a number of ideas for additional tasks or activities or alternatives ways to approach aspects of the lesson. Some of these suggestion are related to the lesson activity. Students can work alone or in pairs rather than in groups for the activity. You could assign a law to specific groups of students to focus on for their presentations. Another idea is for students to find and explain examples of Newton’s laws in real life, such as in their neighborhood, in town, or at home. You could also incorporate Newton’s laws into a math lesson. One more suggestion is to conduct a physics fair for parents where students set up exhibits that demonstrate the three laws of motion.
Teacher Notes
The paragraph on the teacher notes pages describes a little more about what you can expect from this lesson plan. It mentions that students may know the three laws but may not fully understand how they apply to their everyday lives. You may benefit from teaching this lesson at the same time as others on physics. Use the blank lines to write out your ideas or thoughts as you prepare the lesson for your class.
NEWTON’S LAWS OF MOTION LESSON PLAN CONTENT PAGES
Who is sir isaac newton.
The Newton’s Laws of Motion lesson plan contains four pages of content. The first page explains who Sir Isaac Newton is and provides some background information on him. Students will learn that he was an English mathematician, physicist, astronomer, theologian, author, and more! He is one of the most famous and influential scientists of all time. He was a natural philosopher and was a key figure in the scientific revolution. The scientific revolution was a period of events that led to developments in modern science.
When he was 45 years old, Newton published a book called Mathematical Principles of Natural Philosophy that laid the foundations of classical mechanics. In the book, he formulated the laws of motion and universal gravitation. He used his mathematical description of gravity to prove the laws of planetary motion, account for tides, and explain other phenomena. But what people most often tend to think about when someone mentions Sir Issac Newton is the apple falling from a tree and the three laws of motion.
These three laws apply to the physics of force and motion. Scientists have tested and verified the ideas and concepts many times over hundreds of years. Therefore, they now call those ideas Newton’s Three Laws of Motion. The definitions for each law varies across different resources, but the main ideas are the same.
The First Law of Motion
The first law states that an object in motion tends to stay in motion, and an object at rest tends to stay at rest, unless acted upon by an outside, unbalanced force. (You could replace the word “object” with any example to demonstrate the point. The lesson uses “body” as an example for students. If you want, students could take turns naming different objects that stay in motion or stay at rest.)
Most objects tend to naturally remain at rest and not move. For instance, if you place a book on a desk, that book will not move unless someone or something moves it. This tendency is related to an object’s inertia. Inertia is the resistance an object has to a change in its state of motion. The heavier an object is, the more inertia it will have. That is why it is harder to move a boulder than it is to move a book. Newton’s first law is also referred to as the law of inertia.
Students will learn that forces can be either balanced or unbalanced. A balanced force has zero effect on an object. Regarding the example of a book on a desk, the force of gravity on the book balances with the force of the desk holding it. Unbalanced forces imply that the net force on an object is NOT zero. The lesson provides an example of tug-of-war where both sides apply force. The team that will win is the one that applies more force than the other.
A moving object, like a ball rolling along a flat surface, will slow down and stop eventually because of friction. Friction is another type of force. If a surface has a slope, friction will still affect an object rolling down, but gravity is stronger than friction and will enable the object to keep rolling. Air resistance is yet another force that can act upon a moving object.
The Second Law of Motion
The acceleration of an object depends on its force and mass. Another way to put it is that a force acting on an object will change its velocity by changing it speed, direction, or both. This is the second law of motion. An unbalanced force will accelerate an object and change its speed, direction, or both. In the tug-of-war example, adding people to one team will change that team’s force. The second law pertains to situations where the existing forces are unbalanced.
People often use the expression F = ma , or force equals mass times acceleration. An object’s acceleration depends on the net force acting on that object and the object’s mass. Force and acceleration are proportional to each other. That means that the amount of force equal the amount of acceleration. The harder you kick a ball, for instance, the farther and faster the ball will travel. In other words, the greater the force, the greater the acceleration.
The opposite is true of mass. The more mass an object has, the less it will accelerate. If you kick a bowling ball with the same amount of force as you do a soccer ball, the bowling ball will move slower and not go as far. It requires much more force to set a bowling ball in motion than it does a soccer ball. However, the acceleration is always in the same direction as the net force.
The Third Law of Motion
Newton’s third law states that for every action, there is a reaction that is equal in magnitude and opposite in direction. More concisely stated, for every action, there is an equal and opposite reaction. This law relates specifically to the force of an object, or push or pull upon the object. There must be two objects: one pushing and the other being pushed, for instance.
Forces result from the interactions between the two objects. The two forces exerted on the objects are called action and reaction. Friction is actually a type of reaction force. The size of the forces on one object equal the size of the force on the other. The direction of the force on the second object, however, is opposite to the direction on the first. All forces come in pairs—equal and opposite action-reaction pairs.
The lesson explains that you can describe the reaction in terms of strength or magnitude as well as direction. The magnitude of the action equals that of the reaction. If you toss a small stone into water, it will create a small splash and a few ripples. Throwing a boulder into the water creates a larger splash and more ripples.
In these examples, the magnitude of the actions and reactions are the same, but the directions are opposite. The rocks drop down into the water while the water splashes up above the surface. To illustrate this concept further, the lesson describes firing a cannon ball. When the cannon is fired, it jumps backward when the ball projects forward. As a tribute to Newton, the unit for measuring forces using these laws is called a Newton.
NEWTON’S LAWS OF MOTION LESSON PLAN WORKSHEETS
The Newton’s Laws of Motion lesson plan includes three worksheets: an activity worksheet, a practice worksheet, and a homework assignment. Each worksheet will help solidify students’ grasp of the content and help them demonstrate what they learned. The guide on the classroom procedure page explains when to hand out each worksheet to the class throughout the lesson.
DEMONSTRATE THE LAWS ACTIVITY WORKSHEET
Students will work in small groups for the activity. You will need to prepare for this activity beforehand by collecting a number of supplies. Students will write out examples of each law, using the supplies, in the corresponding box on the worksheet. They will then explain how it relates to that specific law. They should have at least two examples for each law.
MATCHING PRACTICE WORKSHEET
There are two sections of the practice worksheet. The first section lists the three laws of motion and then 10 statements. Students must decide which law the statements relate to. For the section section, they will match definitions to the correct terms. There are eight definitions and terms to match.
NEWTON’S LAWS OF MOTION HOMEWORK ASSIGNMENT
The homework assignment requires students to answer 15 questions as they relate to what students learned in the lesson. You may or may not choose to allow students to use the content pages for reference.
Worksheet Answer Keys
The final pages of the lesson plan are answer keys for both the practice and homework worksheets. All the correct answers are in red to make it easy to compare them to the responses from your students. There are a few questions on the homework page that may yield some variation in students’ responses. Keep that in mind as you grade. If you choose to administer the lesson pages to your students via PDF, you will need to save a new file that omits these pages. Otherwise, you can simply print out the applicable pages and keep these as reference for yourself when grading assignments.

The three laws, which were first published in 1867 by Sir Isaac Newton, state: An object at rest will remain at rest until acted upon by an unbalanced force, and an object in motion will remain in motion until acted upon by an unbalanced force. The force needed to accelerate an object is directly proportional to the mass of the object.

Fig. 5.11. Answer The forces acting on a block of mass m at rest on an inclined plane are (i) the weight mg acting vertically downwards (ii) the normal force N of the plane on the block, and (iii) the static frictional force f. opposing the impending motion. In equilibrium, the resultant of these forces must be zero.
Newton's laws of motion. 1. Every body continues in a state of rest or uniform motion (constant velocity) in a straight line unless acted on by a force. (A deeper statement of this law is that momentum (mass x velocity) is a conserved quantity in our world, for unknown reasons.) This tendency to keep moving or keep still is called "inertia.".
