Document Summary
When we are considering motion in the xy plane, these vectors can point anywhere in the plane. A common example of motion in 2d is Consider a projectile fired from a cannon, with an initial velocity. 0v with a direction of above the horizontal. y vy vo vx v v cos. Acceleration is a vector, and can have any direction. But in the special case of acceleration due solely to gravity, the acceleration is always straight down. y a ax = 0 ay = g x. Review of 1d motion: a d v d t v d x d t. From these two equations, we can derive, for the special case a = constant, (a) v (b) (c) x. 2 v (d) v v o x o a t v t o. 2a (x x ) o v xo , vo = initial position, initial velocity x, v = position, velocity at time t.
