Write the formula to calculate the speed of a body moving along a circular path. Give the meaning of each symbol which occurs in it.

Fill in the following blanks with suitable words :

(a) If a body moves with ___________, its acceleration is zero

(b) The ___ of a distance time graph indicates speed of a moving body.

(c) The slope of a ______graph of a moving body gives its acceleration

(d) In a speed-time graph, the area enclosed by the speed-time curve and the time axis gives the ………………by the body.

(e) It is possible for something to accelerate but not change its speed if it moves in a ……………

Is the uniform circular motion accelerated? Give reasons for your Answer.

Explain why, the motion of a body which is moving with constant speed in a circular speed in a circular path is said to be accelerated.

What is the difference between uniform linear motion and uniform circular motion? Explain with examples.
