Acceleration

• Acceleration


  The rate of change in velocity or how quickly something speeds up or slows down
• Acceleration

  • Measured in meters per second squared
• Delta (Δ)


  Means change
• Delta v (Δv)


  Change in velocity, can be written as v - u where v is final velocity and u is initial velocity
• Acceleration

  • Is a vector quantity, has direction as well as magnitude, can be negative (deceleration)
• Acceleration


  • Can be average over time if not constant
• Uniform/constant acceleration


  Acceleration is the same throughout
• Acceleration equation 2


  • Includes distance (s) instead of time (t)
• If an object starts from stationary, its initial velocity (u) is 0
