Projectiles

A projectile is any object that is acted upon by the force of gravity.
Projectile motion has both horizontal and vertical components which must be dealt with individually.
Time does not affect the individual components as they both reach the ground at the same instant.

Vertical projection:
s=ut+1/2at^2
Where u is the initial velocity in the upwards direction.

When projecting an object the following things will be noticeable:
The horizontal position of the object will change by equal distances.
The vertical position will increase at the same rate.
