Uniform Circular Motion

Front

What is Uniform Circular Motion?

Back

Uniform Circular Motion is the motion of an object traveling at a constant speed along a circular path.

Front

What is the direction of centripetal acceleration?

Back

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

Front

What is the formula for centripetal acceleration?

Back

The formula for centripetal acceleration (a_c) is a_c = v²/r, where v is the velocity and r is the radius of the circular path.

Front

What is the role of centripetal force in circular motion?

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 unit of centripetal force?

Back

The unit for centripetal force is Newton (N).

Front

How does speed affect centripetal acceleration?

Back

As the speed of an object increases, the centripetal acceleration increases, provided the radius remains constant.

Front

What happens to centripetal acceleration if the radius of the circular path increases?

Back

If the radius increases while maintaining constant speed, the centripetal acceleration decreases.

Front

What is the relationship between velocity and centripetal force?

Back

Centripetal force is directly proportional to the square of the velocity of the object.

Front

What is the direction of the net force in uniform circular motion?

Back

The net force in uniform circular motion is directed towards the center of the circular path.

Front

What is the difference between linear speed and angular speed?

Back

Linear speed is the distance traveled per unit time, while angular speed is the angle covered per unit time.
