MCQ- 5, ICSE Physics class 10 ch-1 FORCE ,WORK, POWER AND ENERGY

Work, Power, Energy, and Force Quiz

1. Work is said to be done when:

There is a displacement in the direction of force Force is applied but no displacement occurs Object remains stationary Only potential energy changes

2. The SI unit of power is:

newton joule watt newton-metre

3. Power is defined as:

Force per unit time Work done per unit time Energy stored Displacement per unit force

4. If a force of 10 N moves an object by 5 meters, how much work is done?

2 joules 10 joules 50 joules 100 joules

5. The relationship between work, energy, and force is given by:

Work = Force × Distance Energy = Work × Time Force = Work / Energy Power = Force × Time
