Circular Motion

Front

What is Circular Motion?

Back

Circular motion is the motion of an object that travels around a central point or axis, maintaining a constant distance from that point.

Front

What is Centripetal Force?

Back

Centripetal force is the inward force acting on an object moving in a circular path, directed towards the center of the circle.

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 velocity and r is the radius of the circular path.

Front

What happens to Centripetal Force if velocity is tripled?

Back

If the velocity is tripled, the centripetal force increases to 9 times its original value.

Front

What is the direction of Centripetal Acceleration?

Back

Centripetal acceleration acts towards the center of the circular motion.

Front

What is the SI unit for Circumference?

Back

The SI unit for circumference is meter.

Front

What is the relationship between velocity and radius in circular motion?

Back

The relationship is given by the formula v = 2πr/T, where T is the period of rotation.

Front

What is the formula for the gravitational acceleration of a satellite?

Back

The gravitational acceleration (g) at a distance r from the center of the Earth is given by g = v²/r.

Front

What is the effect of increasing the radius on Centripetal Force?

Back

Increasing the radius decreases the centripetal force required to maintain circular motion, assuming velocity remains constant.

Front

What is the difference between Centripetal Force and Centrifugal Force?

Back

Centripetal force is a real force acting towards the center, while centrifugal force is a perceived force that appears to act outward on a body in circular motion.
