What is Projectile Motion?

Projectile motion is a form of motion in which an object or particle (called a projectile) is thrown obliquely near the earth's surface, and it moves along a curved path under the action of gravity only.The path followed by a projectile motion is called its trajectory. Projectile motion only occurs when there is one force applied at the beginning of the trajectory, after which there is no force in operation apart from gravity.

A projectile is any object that is cast, fired, flung, heaved, hurled, pitched, tossed, or thrown. (This is an informal definition.)
Some examples of projectiles-
Any soldier who has to bomb a particular place using an airplane or a tank must calculate the velocity and angle of throw for the bomb to hit the target.

Secondly it is widely used by people who extinguish fire. People who has to extinguish fire in a little longer distance from their stay show the tubes in an angle so that the water hits the fire, thus extinguishing it.

It is also used when, sometimes, food packets are thrown from helicopters in times of intense famine the distance from which the packets are thrown is important. If it is not calculated correctly, the food packets may fall in some other place.

Next it is...
