A body is moving along a circular path of radius $R$. Find the displacement of the body when it completes half a revolution.
$2\,R$
Give an example of a body which covers a certain distance, but its displacement is zero
A motor bike running at $90\, km h ^{-1}$ is slowed down to $18 \,km h^{-1}$ in $2.5\, s$. Calculate
$(i)$ acceleration
$(ii)$ distance covered in the time it slows down
A body can have zero average velocity but not zero average speed. Justify giving an example.
A body is thrown vertically upward with velocity $u$, the greatest height $h$ to which it will rise is,
Distinguish between terms distance and displacement.
Confusing about what to choose? Our team will schedule a demo shortly.
