(i) Why is the motion of a body moving with a constant speed around a circular path said to be accelerated?
(ii) Name the unit of physical quantity obtained by the formula $\frac{2K}{V^2}$.
Where K: kinetic energy, V: Linear Velocity.

(i) The motion of a body moving with a constant speed around a circular path is said to be accelerated because as the direction keeps changing the velocity changes and therefore it's an accelerated motion.
(ii) $\frac{2K}{V^2}$ = $\frac{2 \times (\frac{1}{2} \times mV^2)}{V^2}$ = m.
Therefore, the quantity, $\frac{2K}{V^2}$ will have the unit of mass m which is kilogram (kg).
