Uniform Circular Motion

Front

What is the formula for the circumference of a circle?

Back

C = 2πr, where r is the radius.

Front

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

Back

Speed = Circumference / Period.

Front

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

Back

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

Front

What is the direction of the velocity vector in uniform circular motion?

Back

The velocity vector is tangent to the circular path at any point.

Front

What is centripetal acceleration?

Back

Centripetal acceleration is the acceleration directed toward the center of the circular path.

Front

What keeps an object moving in a circular path?

Back

A net inward force, known as centripetal force, is required to keep an object in circular motion.

Front

What is the formula for centripetal acceleration?

Back

Centripetal acceleration (a_c) = v²/r, where v is the speed and r is the radius.

Front

What is inertia in the context of circular motion?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

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

Back

For a constant period, a larger radius results in a higher speed.

Front

What happens to the speed of an object if the frequency of its circular motion increases?

Back

If frequency increases, the speed of the object also increases.
