Answer:
Potential energy of any object is the energy by virtue of its position, arrangement or state of the object. This energy is stored in an object. There are mainly two types of potential energy namely gravitational and elastic potential energy.
Kinetic energy of any object is the energy due to its motion. It is defined as work needed to accelerate a body from its state of rest to its stated velocity. The kinetic energy depends only on the square of speed of the object unless the object is moving with a much higher speed. i.e. speed comparable to that of light.
Heat is the amount of energy in transit as a result of temperature difference. When you touch a cup of tea you feel hot this happens because the temperature of the cup is higher than your body temperature. Similarly you feel cold when the body you are in contact with has temperature lower than that of yours.
