1. Uniform acceleration – an object which increases one unit of speed, for every one unit of time is constantly, or uniformly, accelerating
Galileo Galilei 1500’s examined motion of objects rolling down inclined planes. Slowly falling, effect of gravity diluted.

2. Uniform acceleration equations UNIFORM ACCELERATION
Average Velocity Vav = Dx/Dt
Average Velocity Vav = (Vf + Vi )/2
Acceleration a = Dv/Dt

Vi = 0
Vf = Vi + aDt
Dx = Vi Dt + ½(aDt2)
Vf = sqrt(Vi2 + 2aDx)
Dx = ½(Vi +Vf )Dt
Vf = aDt
Dx = ½(aDt2)
Vf = sqrt(2aDx)
Dx = ½(Vf )Dt
