Projectile Motion

Projectile Motion

Projectiles move in parabolic paths that can be analysed by considering the horizontal and vertical components of the motion
if air resistance is ignored, the only force on a projectile is its weight, i.e the force of gravity, Force of g or W. This results in the projectile having a vertical acceleration oof 9.8 m s - 2 down during its flight.
The horizontal speed of a projectile remains constant throughout its flight if air resistance is ignored.
An object initially moving horizontally, but free to fall will fall at the exact same, rate and in the same time as an object falling vertically from the same height.
At the point of maximum height, a projectile is moving horizontally. Its velocity at this point is given by the horizontal components of its velocity as the vertical component equals 0.
When air resistance is significant the net force acting on a projectile will not be vertically down, nor will its acceleration. Under these conditions, the path of the projectile is not parabolic.
