When the ball is suspended in the air, gravity is exerting a particular amount of downward force per unit of mass of the ball. Recalling the formula of kinetic energy, we now know that while comparing a truck and a car moving on a road with the same velocity, we will come to the conclusion that the truck will have higher kinetic energy because of its large size. If a number of people are sitting in the wagon, it will increase the mass and, hence, the kinetic energy, provided that the speed remains constant. In each of these cases, kinetic energy is transferred through matter (the rope, water, or air) while the matter remains essentially in place. If they fall, their potential energy will turn into kinetic energy because they are accelerated by gravity. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or various other forms. Gravitational potential energy, energy due to the position of an object, is also a type of mechanical energy. In a windmill, … This is because they have some mass and velocity. When it strikes the pins, some of that energy is passed on to the pins. You can find the number of moles of helium with the ideal gas equation: PV = nRT. The Kinetic Molecular Theory states that all matter is made up of tiny particles that are constantly in motion. These are kinetic energy and potential energy. This is the reason why airplanes are able to fly high. It is a measure of the average kinetic energy of all the particles in a system.
