Circular motion

Front

What is circular motion?

Back

Circular motion is the motion of an object that moves along a circular path. It can be uniform (constant speed) or non-uniform (changing speed).

Front

What is centripetal force?

Back

Centripetal force is the net force that acts on an object moving in a circular path, directed towards the center of the circle.

Front

What is angular velocity?

Back

Angular velocity is the rate at which an object rotates around a center point, measured in radians per second.

Front

What direction does centripetal acceleration act?

Back

Centripetal acceleration acts towards the center of the circle.

Front

What happens to an object in circular motion if the centripetal force is removed?

Back

If the centripetal force is removed, the object will move in a straight line tangent to the circle at the point where the force was removed.

Front

What is the relationship between linear velocity and angular velocity?

Back

Linear velocity (v) is related to angular velocity (ω) by the equation v = rω, where r is the radius of the 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 linear velocity and r is the radius.

Front

What is the radius in circular motion?

Back

The radius is the distance from the center of the circle to any point on its circumference.

Front

What is the effect of increasing the radius on centripetal acceleration?

Back

Increasing the radius decreases the centripetal acceleration if the linear velocity remains constant.

Front

What is the difference between uniform and non-uniform circular motion?

Back

Uniform circular motion has a constant speed, while non-uniform circular motion has a changing speed.
