Define kinetic energy and potential energy and give examples.
Kinetic Energy⇒ The energy possessed by an object in motion is called as the kinetic Energy. It is given by
Kinetic Energy =
Where m = mass of body;
V = velocity of body.
Example = Earth revolving around the sun, you walking down the street etc.
Potential Energy⇒ When the object is at rest the energy possessed by an object is called as the potential energy.
Potential Energy = mgh
Where m = mass of body,
H = height at which body is kept
G = acceleration due to gravity = 9.8 m/s2.
Example = A ball kept at a certain height.
The figure below illustrates the Kinetic and potential energy in more detail.
