circular motion page 7

An object undergoing constant circular motion is

accelerating.

• agree

• dissagree

The centripetal force acting on an object moving in

constant circular motion acts parallel to the direction

of an object’s tangential velocity.

• agree

• dissagree

The greater the mass of an object, the smaller the

centripetal force required to maintain its circular

motion.

• agree

• dissagree

As speed increases, the centripetal force required to

maintain circular motion also increases.

• agree

• dissagree

Radius and centripetal force are directly related.

• agree

• dissagree

Centripetal acceleration is directed toward the center

of a rotating object’s path.
