TEST - Uniform Circular Motion (Vocabulary)

Front

What is the period in uniform circular motion?

Back

The time it takes to complete one revolution (cycle/rotation).

Front

What is frequency in the context of circular motion?

Back

The number of revolutions (cycles/rotations) completed in one second.

Front

What is centripetal acceleration?

Back

Acceleration toward the center of a curved or circular path.

Front

How is centripetal acceleration related to velocity?

Back

Objects experience centripetal acceleration because they are constantly changing direction, which means their velocity is changing.

Front

If a washing machine drum rotates 1800 times in 3 minutes, what is the period?

Back

0.1 seconds.

Front

What is the formula for calculating the period (T) in uniform circular motion?

Back

T = 1/f, where f is the frequency.

Front

What is the relationship between period and frequency?

Back

Period is the reciprocal of frequency; as frequency increases, period decreases.

Front

What happens to the speed of an object in uniform circular motion?

Back

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

Front

What is the direction of centripetal acceleration?

Back

Centripetal acceleration always points toward the center of the circular path.

Front

Can an object moving in a circle at constant speed have acceleration?

Back

Yes, because acceleration is defined as a change in velocity, which includes changes in direction.
