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 the formula for centripetal acceleration?

Back

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

Front

What is the relationship between speed and circular motion?

Back

In circular motion, the speed of an object is constant, but its velocity changes due to the change in direction.

Front

Define 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 the velocity vector in circular motion?

Back

The velocity vector in circular motion is always tangent to the circular path.

Front

What happens to the centripetal acceleration if the speed of the object increases?

Back

If the speed of the object increases, the centripetal acceleration increases as it is proportional to the square of the speed.

Front

What is the effect of increasing the radius on centripetal acceleration?

Back

Increasing the radius decreases the centripetal acceleration for a constant speed, as a_c = v²/r.

Front

What is the direction of centripetal force?

Back

Centripetal force always points towards the center of the circular path.

Front

How does mass affect centripetal force?

Back

Centripetal force is directly proportional to the mass of the object; as mass increases, the required centripetal force also increases.

Front

What is the formula for centripetal force?

Back

Centripetal force (F_c) is given by the formula F_c = mv²/r, where m is the mass, v is the speed, and r is the radius.
