Vedclass · Answer

(B) $1$. Option $A$ is correct: At the highest point of a vertical throw,velocity is $0$ but acceleration is $g$ (downwards).$2$. Option $B$ is wrong: Velocity is a vector quantity defined as $\vec{v} = \vec{v}_{avg} = \frac{\Delta \vec{r}}{\Delta t}$. If velocity is constant,both its magnitude (speed) and direction must remain constant. Therefore,a body with constant velocity cannot have varying speed.$3$. Option $C$ is correct: In uniform circular motion,the speed is constant,but the direction of velocity changes continuously,so velocity is varying.$4$. Option $D$ is correct: In projectile motion,the acceleration is constant ($g$ downwards),but the direction of velocity changes continuously.
