The (4) Equations of (Linear) Kinematics There are four equations connecting uniquely three out of four physical uantities: DISPLACEMENT VELOCITY ACCE ERATION and TIME: quantities: DISPLACEMENT, VELOCITY, ACCELERATION and TIME: v + v GG G ( ) ( ) [ ] 0 00 1. x = x + t t displacement, velocity, time 2 0 2. v = v + a G ( ) [ ] 0 tt v e l o c i t y, acceleration, time G () ( ) [ ] 2 0 0 a 3. x = x + v t t + t t displacement, acceleration, time 2 −− G [ ] 22 4. v = v + 2a x x displacement, speed, acceleration ⋅− G
