A body that is in flight after it is thrown or projected is called a projectile. The motion of the projectile is the result of two separate but simultaneously occurring components of motion. One is the horizontal component without any acceleration and the other is the vertical component with constant acceleration due to gravity. We neglect the effect of air resistance on the motion of the projectile.
The path followed by a projectile is a parabola. The time of flight Tf
is the total time during which the projectile is in motion. The time taken for the projectile to attain maximum height is tm
The maximum height of the projectile as h metres. This height is reached in time tm
. The horizontal distance travelled by the projectile during its time of flight is called the horizontal range. The angle of projection for the maximum range of the projectile is 45°.
