Explanation:

AVERAGE POWER=Average power is defined as the ratio of total work done by the body to the total time taken by the body. The unit of average power is kiloWatt hour.

1 WATT OF POWER = 1 watt is the power of an appliances which consumes energy at the rate of 1 joule per second.

KINTIC ENERGY OF AN OBJECT = Kinetic energy is the energy an object has because of its motion. ... After work has been done, energy has been transferred to the object, and the object will be moving with a new constant speed. The energy transferred is known as kinetic energy, and it depends on the mass and speed achieved.

1 JOULE OF WORK = Joule is the SI unit of work. 1 Joule is amount of work done when a force of 1 Newton displaces a body through a distance of 1m in the direction of the force applied.

When do we say that the work is done?= answer =Work is done whenever the given conditions are satisfied: A force acts on the body. There is a displacement of the body caused by the applied force along the direction of the applied force. The work W is equal to the force f times the distance d, or W = fd.

Average power

IS defined as the ratio of total work done by the body to the total time taken by the body. The unit of average power is kilo watt hour.

1 WATT OF POWER

1 Watt is the power of an appliances which consumes energy at the rate of 1 joule per second.

WHAT IS THE KINETIC ENERGY OF AND OBJECT

Kinetic energy (KE) of an object is the energy possess by the object because of its motion.

KE = 1/2mv2

Where,

m=mass of the object.

v=velocity of the object.
