Circular Motion Review

Front

What is centripetal acceleration?

Back

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

Front

How does centripetal acceleration change if the speed of an object in circular motion doubles?

Back

If the speed doubles, the centripetal acceleration increases by a factor of four.

Front

What happens to centripetal acceleration if the radius of the circular path is halved while maintaining the same speed?

Back

The centripetal acceleration is doubled.

Front

What is the formula for calculating centripetal acceleration?

Back

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

Front

If an object moves in a circle at constant speed, how does its velocity change?

Back

The velocity changes in direction but remains constant in magnitude.

Front

What is the relationship between speed and centripetal acceleration?

Back

Centripetal acceleration is directly proportional to the square of the speed.

Front

What is the direction of the centripetal force acting on an object in circular motion?

Back

The centripetal force acts towards the center of the circular path.

Front

What is the effect of increasing the radius of a circular path on centripetal acceleration, assuming speed remains constant?

Back

Increasing the radius decreases the centripetal acceleration.

Front

In a horizontal circular motion, what remains constant?

Back

The speed of the object remains constant, but the direction of velocity changes.

Front

What is the significance of the term 'uniform circular motion'?

Back

Uniform circular motion refers to motion in a circular path at a constant speed.
