Question

Assuming a frictionless surface, explain how Newton’s three laws of motion are in action as an air hockey puck slides across the table and then hits the side of the table wall.

Explain in detail! Not just a short sentence

Answer 1

As it start sliding, it continues to slide until any external force is not applied to stop it. This is the first law.

Now , since the table is frictionless, so,basically there is no acceleration recorded since net external force is zero.

This is second law, which says that , acceleration is proportional to the force applied.

Now finally, when it hits the side, then it exerts some force on it and in return, side also exerts equal and opposite

force on it which is nothing but the 3rd law.
