An object with greater mass needs a greater ______ to keep it in circular motion.

• centripetal force

• tangential velocity

The more mass an object has the greater the centripetal force is required to keep it moving in a circle.

• true

• false

The greater the radius of the circular path an object is following, the greater the force needed to make it follow that path.

• true

• false

The greater the speed of an object moving in a circular path, the greater the force need to make it travel in that path.

• true

• false
