Projectile is the name given to a body which, after having been given an initial velocity, is allowed to move under the influence of gravity alone. A body projected horizontally with a velocity u from a height h Horizontal and vertical distances covered in time t are Differentiating above equations with respect to time t, we get the horizontal and vertical velocities Equation of trajectory Time of flight Horizontal range Magnitude of resultant velocity at time t The angle α which the resultant velocity vector subtends with the vertical is given by
