It has potential energy because gravity is pulling down on it. It isn’t moving (relative to the ground) so it has no kinetic energy. The cannonball being heavier and moving faster has much more kinetic energy than the soccer ball. An intuitive example of kinetic energy differences would be considering the idea of being hit by a soccer (football) ball or by a cannonball just fired out of a cannon. This would be the ‘energy’ represented by a spinning wheel, or by a car moving down a road. Kinetic Energy is the energy of an object in motion.
Energy exists in two forms, kinetic and potential. The concept of energy is very useful when talking about subjects as broadly different as climate change, electrical power plants, car collisions, explosives, and food diets. For instance, a tank of gasoline has a certain amount of energy that can be released by burning it to achieve useful results, like moving a car a long distance. Energy is a concept that represents the amount of physical work that can be done by a certain system.
