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.

Uniform acceleration equations UNIFORM ACCELERATION Average Velocity Vav = Dx/Dt Average Velocity Vav = (Vf + Vi )/2 Acceleration a = Dv/Dt OBJECTS WITH INITIAL VELOCITY OBJECTS FROM REST 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
