This calculator is ideal for students studying physics, engineers working on various projects, or even hobbyists interested in understanding force interactions.

Formula

The formula that defines Newton’s Third Law is fairly simple:

F_action = – F_reaction

Where:

• F_action is the force exerted by the first body.
• F_reaction is the force exerted by the second body in reaction.

This fundamental equation encapsulates the essence of action and reaction forces, thus forming the backbone of calculations involving Newton’s third law.

Example Calculation

Consider a scenario where a person pushes a wall applying a force of 50 N. According to Newton’s Third Law, the wall will exert an equal and opposite force back onto the person. Here’s how the calculation is illustrated:

Calculation:

F_action = 50 N (force exerted by the person)
F_reaction = – 50 N (force exerted by the wall)

This means that the wall pushes back with a force of 50 N, effectively demonstrating Newton’s Third Law in action.
