KINETIC ENERGY
[edit | edit source]Definition
[edit | edit source]The energy of a moving object is called kinetic energy. The word kinetic means motion.
Examples
[edit | edit source]1. A person walking has kinetic energy. 2. A simple pendulum. 3. A falling ball.
Formula
[edit | edit source]K.E= ½mv² where m is the mass of the object v is the speed or velocity with which it is moving.
POTENTIAL ENERGY
[edit | edit source]Definition
[edit | edit source]The energy stored is called potential energy. it depends upon height or position of the object .
Examples
[edit | edit source]1. A simple pendulum. 2. A person sitting or sleeping. 3. Water stored in a tank.
Formula
[edit | edit source]P.E= mgh where m is the mass of the object g is acceleration due to gravity h is height at which the object is situated from ground level.
MISCELLANEOUS
[edit | edit source]kinetic energy can be converted to potential energy and vice versa. Most of the systems possess both kinetic and potential energy , it depends on the situation or instance when we are looking at the system .
