Circular Motion

Front

What is uniform circular motion?

Back

Uniform circular motion refers to the motion of an object traveling at a constant speed along a circular path.

Front

Why does an object in uniform circular motion experience acceleration?

Back

An object in uniform circular motion experiences acceleration because it is constantly changing direction.

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 type of force is required for a car to make a turn on a road?

Back

Friction force is required for a car to make a turn on a road.

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 circle at the point where the force was removed.

Front

Where is the net force directed when an object is at the top of a vertical loop?

Back

The net force is directed towards the center of the circle when the object is at the top of a vertical loop.

Front

How is velocity related to circular motion?

Back

In circular motion, the velocity of an object is always tangent to the circle and perpendicular to the radius.

Front

What is the relationship between speed and centripetal acceleration?

Back

Centripetal acceleration increases with the square of the speed of the object moving in a circle.

Front

What is the formula for centripetal acceleration?

Back

Centripetal acceleration (a_c) is given by the formula a_c = v^2 / r, where v is the linear speed and r is the radius of the circular path.

Front

What is the difference between centripetal force and centrifugal force?

Back

Centripetal force is the real force acting towards the center of the circle, while centrifugal force is a perceived force that appears to act outward on a mass moving in a circular path.
