Define potential energy and kinetic energy with suitable examples
Answers
Explanation:
This energy can be stored in different forms. Energy is one of the physical quantities as it is proportional to the mass of the object. ... When an object is at rest, the body is said to possess potential energy. In another case, when the object is in motion, then it is said to possess kinetic energy.
Answer:
Answer
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
.
For example, a ball kept at a certain height. The figure below illustrates the Kinetic and potential energy in more detail:
