Circular Motion

Front

What is the net force direction when a rollercoaster is at the top of the loop?

Back

Towards the center of the circle.

Front

Define frequency in the context of circular motion.

Back

Frequency is defined as the number of revolutions (cycles/rotations) completed in one second.

Front

What happens to an object spinning on a string if the string is cut?

Back

The object would move in a straight line.

Front

What is the unit for centripetal force?

Back

Newton (N).

Front

What does the speed of a blowing ball represent in circular motion?

Back

The speed of the ball is depicted by the position labeled C.

Front

What is centripetal acceleration?

Back

Centripetal acceleration is the acceleration directed towards the center of a circular path.

Front

What is the formula for centripetal force?

Back

Centripetal Force (F) = mass (m) × centripetal acceleration (a).

Front

What is the relationship between period and frequency?

Back

Period (T) is the reciprocal of frequency (f): T = 1/f.

Front

What is angular velocity?

Back

Angular velocity is the rate of change of angular displacement and is measured in radians per second.

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 rotated per unit time.
