Uniform circular motion flashcard

Front

What is uniform circular motion?

Back

Uniform circular motion refers to the motion of an object traveling at a constant speed along a circular path.

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

Is centrifugal force a real force?

Back

No, centrifugal force is not a real force; it is a perceived force that appears to push an object outward when it is in circular motion.

Front

What happens to an object in uniform 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 circular path at the point where the force was removed.

Front

What is centripetal acceleration?

Back

Centripetal acceleration is the acceleration that occurs in circular motion, directed towards the center of the circle, and is calculated as a = v²/r.

Front

How do you calculate centripetal acceleration?

Back

Centripetal acceleration (a) can be calculated using the formula a = v²/r, where v is the linear speed and r is the radius of the circular path.

Front

What is the direction of centripetal acceleration?

Back

Centripetal acceleration always points towards the center of the circular path.

Front

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

Back

In uniform circular motion, for a constant speed, an increase in radius results in a decrease in centripetal acceleration.

Front

What is the formula for centripetal force?

Back

Centripetal force (Fc) can be calculated using the formula Fc = mv²/r, where m is the mass of the object, v is the speed, and r is the radius.

Front

What is the effect of mass on centripetal force?

Back

Centripetal force is directly proportional to the mass of the object; as mass increases, the required centripetal force also increases.
