Newton’s Third Law Calculator

How to use the Newton’s Third Law Calculator

1. Fill in the values you know. Fields already contain typical example values that you can overwrite.
2. Pick the unit for each measurement with the selector beside the field; changing a unit converts the number for you.
3. Leave blank the value you want to find, or simply read the results panel, which updates as soon as there is enough information.
4. A value the calculator worked out is shaded in its field. Type over it to switch which quantity is calculated.

If a value is missing or does not make sense, the field shows a short message explaining what to fix.

Formulas used

This calculator is built on the following relationships between its quantities. Each one can be solved for any of the values it contains, which is why you can leave any single field empty and have it calculated from the others:

mass1 × acceleration1 = - (mass2 × acceleration2)

actionForce = mass1 × acceleration1

reactionForce= -(actionForce)

Frequently asked questions

What is Newton’s Third Law of Motion?

Newton’s Third Law of Motion states that for every action, there is an equal and opposite reaction. This means that forces always occur in pairs, ensuring that when one object exerts a force on another, the second object exerts a force of the same magnitude but in the opposite direction on the first object.

How does a Newton’s Third Law Calculator work?

A Newton’s Third Law Calculator takes the input of the force applied by one object and calculates the reaction force exerted by the other object. Users can enter variables such as mass, acceleration, or force to understand the interactions between two objects in a system.

When should I use a Newton’s Third Law Calculator?

You should use a Newton’s Third Law Calculator when analyzing situations involving two objects that interact with each other, such as collisions, explosions, or any scenario where forces are at play. It is particularly useful in physics and engineering applications.

What are some real-world examples of Newton’s Third Law?

Real-world examples include:

• Rocket propulsion: As gases are expelled downwards, the rocket is propelled upwards.
• Walking: When you push your foot back against the ground, the ground pushes your foot forward.
• Swimming: When a swimmer pushes the water backward, they are propelled forward by the reaction force of the water.

Is there a difference between mass and weight in these calculations?

Yes, there is a significant difference. Mass is a measure of the amount of matter in an object and is typically expressed in kilograms (kg), while weight is the force exerted by gravity on that mass and is expressed in newtons (N). Weight can change depending on the gravitational pull, while mass remains constant.

Can I use the Newton’s Third Law Calculator for educational purposes?

Absolutely! The Newton’s Third Law Calculator is a valuable educational tool. It can help students grasp fundamental physics concepts and visualize the relationship between action and reaction forces, making it ideal for homework, lab sessions, or self-study.
