A particle is projected in the air at some angle with horizontal and moves along a parabola as shown in the figure, where x and y indicate horizontal and vertical directions respectively. Show in the diagram, the direction of velocity and acceleration at points A, B, and C.

A particle travelling in a projectile motion will definitely have a path which is parabolic in nature. The velocity of such a particle is always measured tangential to the path of motion. Point B is where the particle reaches maximum height during the projectile motion.

Here we have the vertical and horizontal components of B which are V_{y}=0 and  V_{x}=u\cos \theta
