A:

SIA - Velocity & Acceleration 

  • How it’s written - 
    • Velocity - Units per second 
    • Units/second 
    • Acceleration - units per second per second 
    • Units/second/second 
    • Units/second2 
  • Velocity = displacement/time 
  • Displacement = change in position
  • Average speed = distance/time 
  • Change in x = x final position - x initial position
