According to Newton’s laws of motion, an object set in motion remains in motion unless a force acts on it. If you suspend an object from a string and make it swing, the object will swing for a while, then slow down and stop. Why does the suspended object stop swinging?
- It is because an object at rest remains at rest unless a force acts upon it.
- It is because the mass of the object is too small to maintain the motion.
- It is because energy is the ability to do work.
- It is because gravity is pulling it toward the Earth.
- It is because energy of motion is converted to heat through friction with air.
