Give one example of motion in which speed remains uniform, but the velocity changes.

Name the force required for circular motion. State its direction.

State whether the following statements are true or false by writing T/F against them.

(a) Earth moves around the Sun with a uniform velocity.

(b) The motion of Moon around Earth in a circular path is an accelerated motion.

(c) A uniform linear motion is unaccelerated, while a uniform circular motion is an accelerated motion.

(d) In a uniform circular motion, the speed continuously changes because the direction of the motion changes.

(e) A boy experiences a centrifugal force on his hand when he rotates a piece of stone tied at one end of a string, holding the other end in the hand.

Differentiate between uniform linear motion and a uniform circular motion.
