F + M Equations

• F = ma

  -

  (Resultant) Force (N) = Mass (kg) x Acceleration (m/s2)
• F = ke

  -

  Force (N) = Spring Constant (N/m) x Extension (m)
• Stopping Distance = Thinking Distance + Braking Distance
• Momentum is a Vector Quantity, which means it has direction and magnitude

  -

  Momentum (kg m/s) = Mass (kg) x Velocity (m/s)

  P = m x v
• To find out how much FORCE has changed the overall Momentum of an object, you can use the formula:

  -

  Force (N) = (Final Momentum - Initial Momentum)

  ---------------------------------

  Time (s)
• To find out how much FORCE has changed the overall Momentum of an object, you can use the formula:

  -

  F = (mv - mu)

  ---------

  t
• m = F x d

  OR

  Moment (Nm) = Force (N) x Distance [from Pivot] (m)
