MCQ- 4, ICSE Physics class 10 ch-1 FORCE ,WORK, POWER AND ENERGY

Work, Energy, Power & Force Quiz

1. Work done by a force is zero when:

Force is applied Object moves perpendicular to force Object moves in the direction of force Object remains at rest

2. The relation between work, force, and displacement is:

Work = Force × Displacement Work = Force / Displacement Work = Force × Acceleration Work = Force × Velocity

3. Power is defined as:

Work done per unit time Force per unit time Energy per unit displacement Velocity × Time

4. The energy of a moving object is called:

Potential energy Kinetic energy Electrical energy Chemical energy

5. The work done by a force is maximum when the angle between force and displacement is:

0° 45° 90° 180°
