Turning Forces, Moment of Force, Center of Gravity Quiz

1. What is the moment of force?

A force applied at the center Force × Perpendicular distance Mass × Acceleration Speed × Time

2. The center of gravity of a uniform sphere is at:

The top The bottom The center One of its sides

3. A spanner is used to turn a nut because:

It reduces force It increases turning effect It decreases distance It applies less torque

4. If two equal forces act on an object in opposite directions at different points, they form a:

Linear force Torque Couple Parallel force

5. The center of gravity of an irregularly shaped object can be found by:

Balancing it on a pivot Weighing it Using a force meter Measuring its height

uniform motion and energy

Uniform Circular Motion & Energy Quiz

1. In uniform circular motion, the velocity of the object is:

Constant Changing in magnitude Changing in direction Zero

2. Centripetal force always acts:

Outward from the center Inward towards the center Along the tangent Perpendicular to motion

3. The kinetic energy of an object depends on:

Only mass Only velocity Both mass and velocity Only acceleration

4. Work is said to be done when:

A force is applied There is displacement in the direction of force The object remains at rest Velocity changes

5. The total energy of a freely falling object:

Increases Decreases Remains constant Becomes zero
