FLASHCARD QUESTION

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. The direction of the object's velocity is continuously changing, which means the object is accelerating.

2.

FLASHCARD QUESTION

Front

What is the formula for centripetal acceleration?

Back

Centripetal acceleration (a_c) is given by the formula: a_c = v²/r, where v is the tangential speed and r is the radius of the circular path.

3.

FLASHCARD QUESTION

Front

What is the relationship between period and frequency?

Back

The period (T) is the time taken for one complete revolution, while frequency (f) is the number of revolutions per unit time. They are related by the formula: f = 1/T.

4.

FLASHCARD QUESTION

Front

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

Back

The speed (v) of an object in circular motion can be calculated using the formula: v = 2πr/T, where r is the radius and T is the period.

5.

FLASHCARD QUESTION

Front

What is the unit of centripetal force?

Back

The unit of centripetal force is Newton (N).

6.

FLASHCARD QUESTION

Front

How do you calculate the centripetal force acting on an object?

Back

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

7.

FLASHCARD QUESTION

Front

What is the significance of the radius in uniform circular motion?

Back

The radius determines the size of the circular path and affects both the speed and centripetal acceleration of the object in motion.
