Uniform Circular Motion

Front

What is uniform circular motion?

Back

Uniform circular motion is the motion of an object traveling at a constant speed in a circular path.

Front

What is the formula for calculating the speed of an object in uniform circular motion?

Back

The speed (v) can be calculated using the formula v = 2πr/T, where r is the radius and T is the period.

Front

How do you calculate the centripetal acceleration of an object in uniform circular motion?

Back

Centripetal acceleration (a_c) can be calculated using the formula a_c = v²/r, where v is the speed and r is the radius.

Front

What is the relationship between period and frequency in circular motion?

Back

The period (T) is the reciprocal of frequency (f), given by T = 1/f.

Front

What is the formula for centripetal force?

Back

Centripetal force (F_c) can be calculated using the formula F_c = m * a_c, where m is the mass and a_c is the centripetal acceleration.

Front

What is the unit of centripetal acceleration?

Back

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

Front

How does the radius of a circular path affect the speed of an object in uniform circular motion?

Back

For a constant period, increasing the radius will increase the speed of the object.

Front

What happens to the centripetal force if the speed of the object increases?

Back

If the speed of the object increases, the centripetal force must also increase to maintain circular motion.

Front

What is the direction of the centripetal force in uniform circular motion?

Back

The centripetal force always acts towards the center of the circular path.

Front

How do you find the velocity of an object moving in a circle?

Back

Velocity can be found using the formula v = 2πr/T, where r is the radius and T is the period.
