Circular Motion

Front

What happens to an object in circular motion if the string is cut?

Back

The object moves in a straight line.

Front

What is true about an object in uniform circular motion?

Back

The net force on the object is directed toward the center of the circular path.

Front

How is the velocity of an object in circular motion related to the circle?

Back

The velocity is always tangent to the line of the circle.

Front

What remains constant in uniform circular motion?

Back

The speed of the object.

Front

What changes in uniform circular motion?

Back

The direction of the object's velocity.

Front

What is the net force acting on an object in uniform circular motion?

Back

The net force is directed toward the center of the circular path.

Front

Define uniform circular motion.

Back

Motion of an object traveling at a constant speed along a circular path.

Front

What is centripetal acceleration?

Back

Acceleration directed toward the center of a circular path.

Front

What is the formula for centripetal acceleration?

Back

a_c = v^2 / r, where v is the speed and r is the radius.

Front

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

Back

For a constant centripetal force, increasing the radius decreases the speed.
