If the acceleration of the particle is constant in magnitude but not in direction,what type of path does the particle follow?

$(a)$ Define uniform circular motion.
$(b)$ Is the uniform circular motion an accelerated motion? Give reasons for your answer.

Can a body have constant speed and still be accelerating?

Give an example of a force that merely changes the direction of motion of a body.

Define distance and displacement. $A$ body covers one complete revolution around a circular park of circumference $176 \, m$ in $4$ minutes. Find the displacement of the body after $6$ minutes.

Draw a diagram to show the motion of a body whose speed remains constant but velocity continuously changes.
