Question

Match the columns:

Column 1	Column 2
An object placed in an almirah	Power
A stretched rubber band	Kinetic energy
A moving vehicle	Joule
Work done per unit time	Gravitational potential energy
Capacity of doing work	Elastic potential energy
SI unit of work	Energy

Answer 1

Part A

1. Gravitational potential energy: Energy possessed by an object at rest due to its position above the ground.
2. Thus, Option IV is correct.

Part B

1. Elastic potential energy: energy possessed by an object at rest due to its characteristic configuration. (size and shape)
2. Thus, Option V is correct.

Part C

1. Kinetic energy: The energy possessed by an object due to virtue of its motion.
2. Thus, Option II is correct

Part D

1. Power: Rate of doing work or rate of supply of energy.
2. Thus, Option I is correct.

Part E

1. Energy: The capacity of an object to do work is called energy.
2. Work can be defined as a transfer of energy. Its S.I. unit is joule.
3. Thus, option VI is correct.

Part F

1. Joule: The SI unit of work as well as energy.
2. Thus, Option III is correct.

Hence the correct match is A-IV, B - V, C - II, D -I, E- VI, F - III.
