Question

Which of these objects has potential energy? How do you know?

Object 1: a bicycle on the ground
Object 2: a rock that is about to fall
Object 3: a chair that has been knocked over
Object 4: a golf ball stuck in the pile of grass

Answer 1

Object 2, a rock that is about to fall, has potential energy. This is because potential energy is the energy possessed by an object due to its position or condition. In this case, the rock is elevated and is about to fall, which means it has the potential to do work and convert its potential energy into kinetic energy as it falls.
