Answer 2

Earth

Question 3

What are the three laws of motion?

Answer 3

Law of inertia, law of acceleration, and law of interaction (action - reaction)

Question 4

It states that an object at rest will remain at rest and an object in motion will remain in motion unless there is a force acting upon it

Answer 4

Law of inertia

Question 5
