INDEPENDENCE PRINCIPLE WHAT HAPPENS IN ONE DIMENSION HAS NO INFLUENCE ON WHAT IS HAPPENING IN THE OTHER DIMENSION. THEREFORE, WE CAN DEAL WITH THEM SEPARATELY.

TWO DIMENSIONS X – DIMENSION al t n o oriz H Object moves Y – DIMENSION Object accelerates l forward at a constant speed. Left/Right Forward / Vertica Backwa rd 9. 8 m/s 2 wn o D / p U

1. Gravity does NOT affect the 2. Gravity is the same at ALL points in the trajectory (9. 8 m/s 2 DOWN). 3. Gravity acts IMMEDIATELY. G RAV I T Y F ACT S HORIZONTAL speed of a projectile.

Example 1 : Bullets X – DIMENSION HORIZONTAL FIRED BULLET DROPPED BULLET Y – DIMENSION VERTICAL Because they are the SAME it means that both bullets will reach the ground together.

Example 2 : Bridges X – DIMENSION HORIZONTAL BETTY BRIDGE BOB AIR Y – DIMENSION VERTICAL Because they are the SAME it means that both will reach the other side together.

Example 3 : Monkeys X – DIMENSION HORIZONTAL Y – DIMENSION VERTICAL MONKEY NOTHING FALLS 9. 8 M/S 2 BULLET MOVES FORWARD AT A CONSTANT SPEED FALLS 9. 8 M/S 2 Because they are the SAME it means that you will hit the monkey if you aim right at it.
