Circular Motion

Front

What is centripetal acceleration?

Back

Centripetal acceleration is the acceleration directed towards the center of a circular path, necessary for an object to maintain circular motion.

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 linear speed and r is the radius of the circular path.

Front

What is the relationship between period and frequency?

Back

Frequency (f) is the reciprocal of the period (T). f = 1/T, where T is the time taken for one complete cycle.

Front

What is the period of an object in circular motion?

Back

The period is the time taken for one complete revolution around the circle.

Front

What does it mean for velocity to not be constant in circular motion?

Back

In circular motion, velocity is not constant because the direction of the velocity vector changes continuously, even if the speed remains constant.

Front

What is the direction of centripetal acceleration?

Back

Centripetal acceleration always points towards the center of the circle.

Front

What is angular velocity?

Back

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

Front

How does mass affect centripetal force?

Back

Centripetal force is directly proportional to mass; as mass increases, the required centripetal force to maintain circular motion also increases.

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.

Front

What is the formula for calculating the centripetal force?

Back

The formula for centripetal force (F_c) is F_c = m * a_c, where m is the mass of the object and a_c is the centripetal acceleration.
