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

What type off motion is represented by the tip of ‘seconds’ hand’ of watch? Is it uniform or accelerated?

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 ……………

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.

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.
