 Effect of a Force

 

Force can change the shape and the original state of motion (direction @ speed) of an object.

 
  Force formula  
  \(F= ma\), where m = mass and a = acceleration ​​​  
     
 
Forces in equilibrium Forces not in equilibrium
  •  Velocity constant @ stationary
  • Acceleration \(= 0\text{ ms}^{-2}\)
  • Resultant force \(= 0\text{ N}\)
  •  Velocity is not constant
  • Acceleration \(\neq 0 \text{ ms}^{-2}\)
  • Resultant force \(\neq 0 \text{ N}\)
