Effect of a Force

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 \(\neq 0 \text{ N}\)
