Circular 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 is the direction of centripetal force in circular motion?

Back

The direction of centripetal force is towards the center of the circular path.

Front

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

Back

If the centripetal force is removed, the object will move in a straight line tangent to the circular path.

Front

What is the formula for centripetal acceleration?

Back

Centripetal acceleration (a_c) = v²/r, where v is the speed and r is the radius of the circular path.

Front

What is the unit of centripetal force?

Back

The unit of centripetal force is Newton (N).

Front

What does the period of circular motion refer to?

Back

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

Front

What is the relationship between period and frequency in circular motion?

Back

Frequency (f) is the reciprocal of the period (T): f = 1/T.

Front

What is angular velocity?

Back

Angular velocity (ω) is the rate of change of angular displacement and is measured in radians per second.

Front

What is the formula for angular velocity?

Back

Angular velocity (ω) = θ/t, where θ is the angular displacement in radians and t is the time in seconds.

Front

What is the difference between linear velocity and angular velocity?

Back

Linear velocity refers to the speed of an object along a circular path, while angular velocity refers to the rate of rotation around a center point.
