Consider a projectile is thrown with a velocity $u$ making an angle $\theta$ with the horizontal.
- At maximum height, the velocity along the $y-$ axis is zero.
- Velocity along $x-$ is constant throughout out the motion.
- Vertical velocity varies same as the motion under gravity.
- Vertical and horizontal motion are independent of each other.
- The only gravitational force acts on the body in the vertically downward direction during the motion.
- So, velocity along the $y-$ axis (vertical direction) varies and the velocity along the $x-$ axis (horizontal direction) remains constant.
