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 centripetal acceleration?

Back

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

Front

What is the direction of centripetal acceleration?

Back

Centripetal acceleration always points towards the center of the circle.

Front

What keeps an object moving in a circular path?

Back

Centripetal force is required to keep an object moving in a circular path.

Front

What is the relationship between speed and radius in uniform circular motion?

Back

For a constant centripetal acceleration, if the speed increases, the radius must decrease to maintain the same acceleration.

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, which helps keep the water in a bucket when swung in a circle.

Front

How does mass affect centripetal acceleration?

Back

Centripetal acceleration is independent of mass; it depends only on speed and radius.

Front

What happens to centripetal acceleration if the speed is doubled?

Back

If the speed is doubled, the centripetal acceleration increases by a factor of four (a_c = v²/r).

Front

What is the role of friction in circular motion?

Back

Friction can provide the necessary centripetal force to keep an object moving in a circle, but it is not the only force that can do so.

Front

What is the difference between linear velocity and angular velocity?

Back

Linear velocity is the speed of an object along a circular path, while angular velocity is the rate of change of the angle with respect to time.
