What is the time taken for one complete circuit called?

Back

Period

Front

If the speed limit is 20 m/s and the centripetal acceleration cannot exceed 8.5 m/s², how big must the radius of the turn be?

Back

47 m

Front

Calculate the centripetal force of a 50 kg object traveling at 2 m/s around a 25 m radius.

Back

8 N

Front

What happens if you double the velocity in the centripetal force equation?

Back

4F

Front

Calculate the mass of an object if it took 20 N to rotate it in a circle with a radius of 2 meters with a velocity of 4 m/s.

Back

2.5 kg

Front

Define centripetal acceleration.

Back

Centripetal acceleration is the acceleration directed towards the center of a circular path, calculated as a_c = v²/r.

Front

What is the formula for centripetal force?

Back

Centripetal force (F_c) is given by F_c = m * a_c, where a_c is the centripetal acceleration.

Front

What is the relationship between period and frequency?

Back

Frequency (f) is the reciprocal of the period (T), f = 1/T.

Front

How does increasing the radius affect centripetal acceleration?

Back

Increasing the radius decreases the centripetal acceleration for a constant speed.

Front

What is the unit of centripetal acceleration?

Back

The unit of centripetal acceleration is meters per second squared (m/s²).
