Newton’s laws of motion provides that an object set in motion remains in motion unless a force acts on it. If you suspend a ball from a tree with a piece of string and make it swing, the ball will swing for a while, then slow down and stop.Why does the ball stop swinging?

because gravity is pulling it toward the Earth
because an object at rest remains at rest unless a force acts upon it
because energy of motion is converted to heat through friction with air
because energy is the ability to do work
because the mass of the object is too small to maintain the motion
