Projectile+Motion

=Projectile Motion=

=Horizontal Projectile= - A projectile launched parelell to the ground.

When an object is in horizontal projectile motion only the force of gravity is acting on it. Therefore, the horizontal velocity does not change. However, the verticle velocity does change by -9.8(m/s²).

Since the horizontal velocity does not change we can use the constant velocity eqation, d = tv. Since the vertical velocity changes we must use these equations: Vf = Vi + at ; d = 1/2at² + Vit.

=Ground to Ground= - Launched from ground to ground at an angle. The objects horizontal velocity still does not change. To find the horizontal velocity find the x-component of the launch vector. The verticle velocity still changes by -9.8(m/s²). To find the initial verticle velocity find the y-component of the launch vector.

Since the horizontal velocity does not change we can use the constant velocity equasion, d = tv. Since the verticle velocity changes we must use these equations: Vf = Vi + at; d = 1/2at² + Vit.

=NOTE:= If you subtract a launch angle from 90 the result will hit the same position when used as the launch angle. A 45° launch angle will go the farthest and therefore is the maximum range of the cannon.
