Recall Questions Define 1N?? The force required to give a mass of $1kg$ an acceleration of $1ms^{-2}$.
What is a resultant (net) force?? The vector sum of all the forces acting on an object.
What is the relationship between resultant force and acceleration, assuming mass remains constant?? $$F = ma$$
Describe the motion of an object with a resultant force of $0N$ acting on it?? Zero acceleration (therefore stationary or constant velocity).
What direction does friction/drag act in?
