- Any object in flight after being thrown with some velocity is called a projectile and its motion is called projectile motion.

- A bowler bowls a ball towards a batsman in cricket, a basket ball player throws a ball towards the basket, all these are illustrations of projectile motion.

- In this motion, we have objects (projectiles) with given initial velocity, moving under the influence of the Earth's gravitational field.

- The projectile has two components of velocity, one in the horizontal, i.e., along x-direction and the other in the vertical, i.e., along the y direction.

- The acceleration due to gravity acts only along the vertically downward or direction.
- The acceleration due to gravity acts only along the vertically downward or direction.
- The horizontal component of velocity, therefore, remains unchanged as no force is acting in the horizontal direction, while the vertical component changes in accordance with laws of motion with a x being 0 and a y (= g ) being the downward acceleration due to gravity (upward is positive).

- Unless stated otherwise, retarding forces like air resistance, etc., are neglected for the projectile motion.
