it is the difference of the potential energy when the body is on the table and from the position where it is dropped.
When an object is dropped, its potential energy decreases. This is because potential energy is a result of an object's position or height above the ground. As the object falls, it loses height, which leads to a decrease in potential energy. At the same time, the object gains kinetic energy, which is the energy of motion.
Kinetic
Potential to kinetic.
Potential energy refers to the energy of an object that is released as kinetic energy when it falls back to the ground. When a stone is dropped from a height of 5m, its speed when it hits the ground is 9.9 m/s.
Whenever anything falls down, potential gravitational energy is converted to kinetic energy.
when a coin is falling it is losing kinetic energy when it lands it is gaining potential. kinetic energy is the energy of movement. potential is the energy of stillness.
Since the penny was up and stationary before (in your hand or wherever), it had potential energy at first. When it's dropped, it is converted into kinetic energy (energy of motion).
Kinetic energy increases and gravitational potential energy decreases.
It's exactly the gravitational potential energy that the stone had, relativeto the ground, before it was dropped:M G H = (9.8) x (the stone's mass) x (the height of the building) joules
Whenever an object falls, its potential energy is first of all converted to kinetic energy.
The potential energy it had at height x when it was not moving is equal to the kinetic energy it will have as it is falling. Why? Law of the Conservation of Energy. Energy before will equal energy after.
The longer it falls the more kinetic energy it gets while decreasing it's potential energy.
