Define projectile motion .

Explanation

A projectile moves under the combined effect of two velocities.
(i) A uniform velocity in the horizontal direction, which will not change provided there is
no air resistance.
(ii) A uniformly changing velocity (i.e., increasing or decreasing) in the vertical direction.
There are two types of projectile motion: (i) Projectile given an initial velocity in the horizontal direction (horizontal projection)
(ii) Projectile given an initial velocity at an angle to the horizontal (angular projection) To study the motion of a projectile, let us Projectile given an initial velocity at an angle to the horizontal (angular projection) To study the motion of a projectile, let us Projectile given an initial velocity at an angle to the horizontal (angular projection) To study the motion of a projectile, let us assume that,
(i) Air resistance is neglected.
(ii) The effect due to rotation of Earth and curvature of Earth is negligible.
(iii) The acceleration due to gravity is constant in magnitude and direction at all points of the motion of the neglected.
