Kinetic energy is energy due to motion and potential energy is energy due to position in a force field. The formula for translational kinetic energy is KE = 0.5*m*v^2, where m is mass and v is velocity. The most common type of potential energy is gravitational potential energy, and near the surface of the Earth (or some other planetary body) the formula is PE = mgh, where m is mass, g is acceleration due to gravity, and h is the height above the surface. Another common one is elastic potential energy in a compressed spring. In that case the formula is PE = 0.5*k*x^2, where k is the spring constant and x is the compression. An object can also have electrical potential energy, if it has an electrical charge and is positioned some distance from another charge.

Kinetic energy is the energy possessed by a body when in motion and is 0.5mv^2 whereby 0.5 is a constant, m is the mass of the body and v is the velocity of the body in the motion.
Potential energy is the energy a body possess when in rest and is denoted by mgh whereby m is the mass of the body, g is the gravitational acceleration which is a constant (10ms^-2) and h is the height at which the body is from the ground surface.

Kinetic energy is energy in motion, like a rolling ball. Potential energy is like..a ball at the top of a hill, it could roll, it has potential.

kinetic energy is the energy possessed by moving body where
as potential energy is the possessed by a stationery object .this can due to change in size,shape or height from ground

kinetic energy is the energy possessed by a body by virtue of its motion. the expression for KE is KE=(1/2)m(v^2)
where m is the mass of the body and v is the velocity of the body.
PE is the energy possessed by a body by virtue of its position or shape. it is of 2 types- elastic PE and gravitational PE. eg. the energy possessed by a stretched spring is called elastic PE.when a body is kept at a height above the earth's surface, it is said to possess gravitational PE.

kinetic energy :it is the energy possessed by a body when it is moving
potential energy :it is the energy possessed by a body due to its position or height

I agree with the above. in most equations in practical science potential energy is written as the elevation that object is.

ke is due 2 motion
pe is due 2 position
