Question

place the skater and skate track in space. how can this scenario validate Newton's law of motion ?

Answer 1

Let's consider our man as " jerod"

Action and Reaction

Newton’s third law of motion explains how Jerod starts his skateboard moving. This law states that every action has an equal and opposite reaction. This means that forces always act in pairs. First an action occurs—Jerod pushes against the ground with his foot. Then a reaction occurs—Jerod moves forward on his skateboard. The reaction is always equal in strength to the action but in the opposite direction.

Q: If Jerod pushes against the ground with greater force, how will this affect his forward motion?

A: His action force will be greater, so the reaction force will be greater as well. Jerod will be pushed forward with more force, and this will make him go faster and farther.
