Question

1. What is Newton's first law of motion
and when does it occur during this experiment?

Answer 1

Newton’s first law of motion, or inertia is an object at rest stays at rest. I may not be able to answer the second question, I do not know what the experiment is or what it is about.

Answer 2

For example if you would put an object on your car and drive and if you would turn left, the object would move on in the direction the car was driving before it turned left. It keeps its direction.
