What is a Projectile? What is Projectile Motion and what are different equations used in projectile motion?

A particle moving under the combined effect of vertical and horizontal forces, is called a projectile. The following terms are commonly used in projectiles:

1. Trajectory. It is the path traced by a projectile in the space.

2. Velocity of projection. It is the velocity with which a projectile is projected.

3. Angle of projection. It is the angle,with the horizontal,at which the projectile is projected.

4. Time of flight. It is the total time taken by a projectile, to reach maximum height and to return back to the ground.

5. Range. It is the distance between the point of projection and the point where the projectile strikes the ground.
