Question

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

Answer 1

In projectile motion horizontal component of velocity will always be constant and acceleration is always vertically downwards and is equal to the gravity $\left(g\right)$. Direction of velocity will always be tangential to the curve in the direction of motion.


Final answer: Horizontal component of velocity will always be constant and acceleration is always vertically downwards.
