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 centripetal acceleration?

Back

Centripetal acceleration is the acceleration directed towards the center of a circular path, responsible for changing the direction of the object's velocity.

Front

What direction does centripetal acceleration point in uniform circular motion?

Back

Centripetal acceleration always points towards the center of the circle.

Front

What is the formula for centripetal acceleration?

Back

The formula for centripetal acceleration (a_c) is a_c = v²/r, where v is the speed and r is the radius of the circular path.

Front

What happens to centripetal acceleration if the speed of the object increases?

Back

If the speed of the object increases, the centripetal acceleration increases as well.

Front

What is the role of friction in uniform circular motion?

Back

Friction provides the necessary centripetal force that allows an object to move in a circular path.

Front

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

Back

As the radius decreases, the speed of the object must also decrease to maintain uniform circular motion.

Front

What is the formula for calculating the net force in uniform circular motion?

Back

The net force (F_net) can be calculated using F_net = m * a_c, where m is the mass and a_c is the centripetal acceleration.

Front

What is the difference between centripetal force and centrifugal force?

Back

Centripetal force is the real force acting towards the center of the circle, while centrifugal force is a perceived force that appears to act outward on a mass moving in a circular path.

Front

How does mass affect centripetal force?

Back

Centripetal force increases with mass; a larger mass requires a greater centripetal force to maintain circular motion.
