Circular Motion

Front

What is centripetal acceleration?

Back

Centripetal acceleration is the acceleration that occurs in circular motion, directed towards the center of the circle.

Front

What direction does centripetal acceleration always point?

Back

Towards the center of the circle.

Front

What is the formula for the circumference of a circle?

Back

C = 2πr, where r is the radius.

Front

If a ball is revolving clockwise, what is the direction of the acceleration at point A?

Back

Down.

Front

What is the speed of an object in circular motion if it makes 5 revolutions per second and the radius is 0.3 meters?

Back

9.4 m/s.

Front

Define rotation in the context of circular motion.

Back

Rotation is the process or act of turning or circling around something.

Front

What is the relationship between speed and radius in circular motion?

Back

Speed is directly proportional to the radius and the frequency of rotation.

Front

What is the formula for calculating speed in circular motion?

Back

Speed (v) = Circumference (C) / Time (T).

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 unit of measurement for angular speed?

Back

Radians per second (rad/s).
