Circular motion

Front

What is centripetal acceleration?

Back

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

Front

What direction does centripetal acceleration act in circular motion?

Back

Centripetal acceleration acts towards the center of the circular motion.

Front

What is uniform circular motion?

Back

Uniform circular motion is the motion of an object traveling at a constant speed in a circular path.

Front

What causes centripetal acceleration?

Back

Centripetal acceleration is caused by a change in the direction of the velocity vector of an object in circular motion.

Front

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

Back

True.

Front

What is the formula for centripetal acceleration?

Back

The formula for centripetal acceleration (a_c) is a_c = v^2 / 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, speed can remain constant, but the direction of the velocity vector changes continuously.

Front

What is the difference between linear speed and angular speed?

Back

Linear speed is the distance traveled per unit of time, while angular speed is the rate of rotation around a center point.

Front

What is the role of tension in circular motion?

Back

Tension can provide the necessary centripetal force to keep an object moving in a circular path, such as in a string or rope.

Front

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

Back

Increasing the radius of the circular path decreases the centripetal acceleration for a constant speed.
