How do newtons first and third laws describe the motion of an object?

Newton's laws of motion relate an object's motion to the forces acting on it.

Explanation:

In the first law, an object will not change its motion unless a force acts on it. ... In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

In the first law, an object will not change its motion unless a force acts on it. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

pe = weightxheight = 2000x1000=2,000,000joules

it is called kinetic energy
