A=∆v/timeVelocity and acceleration don’t have to be in the same direction.Ex) a ball thrown up is accelerating down.

square each distance and add. Then take the square root.

V=displacement/timeIf displacement is 0 then V=0

Linear motion equations (require constant acceleration) (think projectile)

Question	Answer
Acceleration	A=∆v/timeVelocity and acceleration don’t have to be in the same direction.Ex) a ball thrown up is accelerating down.
Net displacement	square each distance and add. Then take the square root.
Velocity	V=displacement/timeIf displacement is 0 then V=0
Linear motion equations (require constant acceleration) (think projectile)	X=x₀ + v₀t + ⅟₂ at²V= v₀ + atv²=v₀² + 2ax
average velocity	Avg. V = ⅟₂ (v+v₀)
