2. Equations of motion and free fall

• The equation for acceleration is a = (v - u) / t, where a is acceleration, v is final velocity, u is initial velocity, and t is time.
• Free fall is the acceleration under gravity with no other acting force
• What is the value of the acceleration of free fall on Earth?


  9.81ms^-2
• suvat equation without displacement:


  at=v-u
• suvat equation without final velocity


  s=ut+0.5at^2
• suvat equation without acceleration


  2s=t(u+v)
• suvat equation without time


  $v^2-u^2=$$2as$
