Question

an object move with uniform speed in a circle with radius r. calculate the distance and displacement when (a) when it complete half cricle (b) when it complete the full circle​

Answer 1

Explanation:

distance when it completes half circle

$2\pi \times r \div 2 = \pi \times r$

displacement when it completes half circle =2r

distance when it completes full circle=

$2\pi \times r$

displacement when it completes full circle=0
