Student Projects/Kinetic Energy and Potential Energy
KINETIC ENERGY edit
Definition edit
The energy of a moving object is called kinetic energy. The word kinetic means motion.
Examples edit
1. A person walking has kinetic energy. 2. A simple pendulum. 3. A falling ball.
Formula edit
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
Definition edit
The energy stored is called potential energy. it depends upon height or position of the object .
Examples edit
1. A simple pendulum. 2. A person sitting or sleeping. 3. Water stored in a tank.
Formula edit
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
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 .
