Projectile motion is a form of motion moves along a curved path under the action of gravity only.
Horizontal Displacement at Time: Δx = Vx0t
where, t = Time, Vx0 = Initial Horizontal Velocity, Δx = Horizontal Displacement at Time.
For example, when Initial Horizontal Velocity is 10 m/s, Time is 2 s. then Horizontal Displacement at Time(Δy) = 20m.
