2. Four Major Types of Two Dimensional Motion 1. Projectile Motion 2. Circular Motion 3. Rotational Motion 4. Periodic Motion

4. Projectile motion problems are best solved by treating horizontal and vertical motion separately.  IMPORTANT  Gravity only affects vertical motion. There are two general types of projectile motion situations. 1. object launched horizontally 2. object launched at an angle

5. Object Launched Horizontally v 0 = initial horizontal velocity R = horizontal range h = initial height above ground t = total time in the air IMPORTANT FACTS There is no horizontal acceleration. There is no initial vertical velocity. The horizontal velocity is constant. Time is the same for both vertical and horizontal. horizontal R = v 0 . t vertical h = 0.5 . a g . t 2
