Document Summary
6 motion in two dimensions: projectile motion (pg 88) Balls flying through the air, long jumpers, and cars doing stunt jumps are all examples of the two-dimensional motion that we call projectile motion. A projectile is an object that moves in two dimensions under the influence of gravity and nothing else. The horizontal and vertical components of an object undergoing projectile motion are independent of each other. The acceleration of a projectile is the same as the acceleration of an object falling straight down- namely, free-fall acceleration. The vertical component of acceleration ay for all projectile motion is just the familiar g of free fall, while the horizontal component ax is zero.
