Uniform Circular Motion

Front

What is Uniform Circular Motion?

Back

Uniform Circular Motion is the motion of an object traveling at a constant speed along a circular path.

Front

What is the direction of centripetal force in uniform circular motion?

Back

The centripetal force always acts towards the center of the circular path.

Front

What happens to the velocity of an object in uniform circular motion?

Back

The speed remains constant, but the velocity changes due to the continuous change in direction.

Front

What is the relationship between centripetal acceleration and speed?

Back

Centripetal acceleration is directly proportional to the square of the speed and inversely proportional to the radius of the circular path.

Front

What is the formula for centripetal acceleration?

Back

Centripetal acceleration (a_c) = v²/r, where v is the speed and r is the radius.

Front

What is the direction of acceleration in uniform circular motion?

Back

The acceleration is directed towards the center of the circle.

Front

How does the net force act on an object at the top of a vertical loop?

Back

At the top of a vertical loop, the net force acts downwards towards the ground.

Front

What is the effect of stopping the centripetal force on an object in circular motion?

Back

If the centripetal force stops, the object will move off in a straight line tangent to the circle at that point.

Front

What is the difference between speed and velocity in circular motion?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is the role of tension in circular motion for an object on a string?

Back

Tension provides the necessary centripetal force to keep the object moving in a circular path.
