Centripetal Motion

Front

What is centripetal force?

Back

Centripetal force is the net force that acts on an object moving in a circular path, directed towards the center of the circle.

Front

What happens to the centripetal force if the velocity is tripled?

Back

If the velocity is tripled, the centripetal force increases to 9 times its original value.

Front

What is the formula for centripetal acceleration?

Back

Front

What is the period of an object in circular motion?

Back

The period is the time taken for one complete revolution around the circle.

Front

What is the relationship between frequency and period?

Back

Front

What happens to an object in circular motion if the centripetal force is removed?

Back

The object will move in a straight line at a tangent to the circle at the point where the force was removed.

Front

How do you calculate centripetal force?

Back

Front

What is the unit of centripetal force?

Back

The unit of centripetal force is Newton (N).

Front

If a 5 kg ball moves at 4 m/s in a circle of radius 2 m, what is the centripetal force?

Back

The centripetal force required is 40 N.

Front

What is the significance of the radius in circular motion?

Back

The radius determines the curvature of the path and affects the centripetal force and acceleration.
