Question

define Kinetic and potential energy ?​

Answer 1

Explanation:

KInetic energy is the energy possessed by the virtue of motion of a body. It is given by:

Kinetic energy K.E=

2

mv

2

where, m = mass of body

v = velocity of body.

For example, Earth revolving around the sun, you walking down the street etc.

Potential Energy is the energy possessed by an object at rest by virtue of its position. It is given by:

Potential energy P.E=m×g×H

where, m = mass of body

H = height at which body is kept

g = acceleration due to gravity = 9.8m/s

2

.

Answer 2

Potential energy - Energy stored in an object due to its position is Potential Energy. Potential energy, stored energy that depends upon the relative position of various parts of a system. ... A spring has more potential energy when it is compressed or stretched.

Kinetic energy-In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.
