Prepared by Vince Zaccone For Campus Learning Assistance Services at UCSB Projectile motion is a combination of Horizontal and Vertical motion We use separate sets of formulas for each, but both motions happen simultaneously.

Horizontal Recall the formulas for linear motion with constant acceleration: In the case of projectiles, with no air resistance, The horizontal motion is very simple: The acceleration is zero, so the horizontal component of the velocity is constant Vertical ( 29 2 2 2 2 1 x x a 2 v v at v v at t v x x + = + = + + = (1) (2) (3) Prepared by Vince Zaccone For Campus Learning Assistance Services at UCSB Projectile motion is a combination of Horizontal and Vertical motion We use separate sets of formulas for each, but both motions happen simultaneously. Horizontal In the case of projectiles, with no air resistance, a = 0, so the formulas become: Vertical The horizontal component of V is constant!

Horizontal In the case of projectiles, with no air resistance, a = 0, so the formulas become: Vertical The vertical component of the motion is just freefall. This means the acceleration is constant, towards the ground, with magnitude g = 9.8m/s 2 a v v t v x x x x , x x , = = + = The horizontal component of V is constant!
