Circular Motion

Front

What is Circular Motion?

Back

Circular motion is the motion of an object that revolves around a fixed point or axis in a circular path.

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 formula for Centripetal Force?

Back

F_c = (mv^2)/r, where F_c is centripetal force, m is mass, v is velocity, and r is the radius of the circular path.

Front

What is Centripetal Acceleration?

Back

Centripetal acceleration is the acceleration experienced by an object moving in a circular path, directed towards the center of the circle.

Front

What is the formula for Centripetal Acceleration?

Back

a_c = v^2/r, where a_c is centripetal acceleration, v is velocity, 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

How does speed affect Centripetal Force?

Back

As speed increases, the centripetal force required to maintain circular motion increases.

Front

What happens to Centripetal Force if the radius of the circle increases?

Back

If the radius increases while maintaining the same speed, the centripetal force decreases.

Front

True or False: An object in circular motion is constantly changing its velocity.

Back

True.

Front

What direction does Centripetal Acceleration point?

Back

Centripetal acceleration always points towards the center of the circle.
