Circular Motion Quiz

What happens to an object if no net force is applied to it?

• It will accelerate.

• It will remain stationary or move at a constant speed.

• It will deflate.

• It will move in a circular path.

What force is responsible for keeping an object in circular motion?

• Frictional force

• Centripetal force

• Gravitational force

• Magnetic force

In the pendulum experiment, what does the angle of deflection indicate?

• The magnitude of the force applied

• The weight of the pendulum

• The length of the string

• The speed of the pendulum

What happens to the deflection of the pendulum when the speed increases?

• The deflection increases.

• The deflection becomes zero.

• The deflection remains the same.

• The deflection decreases.

According to the experiment, what effect does a smaller radius have on the required force for circular motion?

• It requires less force.

• It requires more force.

• It makes the force zero.

• It has no effect on the force.
