Newton’s Third Law – Examples, PDF
Three laws of motion will dictate and explain the various mechanisms and forces that we use to move, act, and utilize specific actions and objects. One of the most important laws of motion is Newton’s third law of motion.

What Is Newton’s Third Law?
Newton’s third law of motion indicates when an object exerts a force on another object and experiences the same amount of force from the exerted object. People have used this law of motion to help predict the amount of force an object will experience and give back to the object exerting the force.
How to Calculate Newton’s Third Law
You can properly use Newton’s third law to help predict the displacement of the object or if the object has enough tension to maintain a hanging position. If you want to learn more about the 3 laws of Newton and Newton’s 3rd law, you may use any of Newton’s 3rd law examples and samples on the links above.
Step 1: Determine Which Formula You Will Need To Use
There are two formulas people can use to calculate Newton’s third law. T = W = mg for a free hanging mass and Fnet = T – W for movement. Determine which type of formula you will use for the specific problem.
Step 2: Write Down and Identify All the Variables
After you have determined the formula you will use, you must write down all the variables the problem has laid out for you. Be sure that each variable in the problem has the correct measurements, if they do not have the appropriate measurements be sure to convert them as necessary.
Step 3: Substitute the Variables for the Appropriate Things in the Formula
Substitute the given variables to the formula of net force or tension. This will give you the missing value you will need to find in the formula. Be sure to move the unidentified value to the left side of the equation by doing the appropriate steps.
Step 4: Solve the Solution
Solve for the missing value and be sure it will have the correct measurement associated with the missing value. If it doesn’t have the correct measurement, convert it accordingly.
FAQs
What are the uses of Newton’s third law?
Newton’s third law of motion allows people to know how much external force is required to disturb the equilibrium or balance of an object to move it in a specific direction. This is important as many of our basic actions and tools require movement. Newton’s third law will try to explain how much kinetic energy, mechanical energy, potential energy, or electrical energy is needed to disturb an object and move it a specific distance and direction.
What are real-life examples of Newton’s third law of motion?
We do many everyday actions that utilize Newton’s third law of motion. One real-life example of Newton’s third law of motion you can observe is when a person cuts wood products into small chunks using an ax. The person can unconsciously predict how much force they need to exert to change the raw wood commodity into a small wooden product. Another example we can observe is when a service tow truck tows a broken car to the nearest mechanic. The truck will need a specific amount of force to both tow the car and drive in a specific direction.
What is the difference between Newton’s second and third law of motion?
Newton’s second law of motion refers to the law of motion that calculates the acceleration of two objects when said objects will apply the summation of their forces. Newton’s third law of motion refers to the amount of net force needed to move an object to another place. These two laws of motion work hand-in-hand to help us understand how vehicles and other things move at an accelerated pace.
Newton’s third law of motion outlines how an object can displace another object with the appropriate amount of force. When planning to move something heavy or require a lot of energy, it is important to know how to be efficient when doing those said actions.
