Objects resist changes to their motion; this is inertia. More mass means more inertia.

Acceleration is in the same direction as the resultant force. Double the force doubles the acceleration.

The two forces are equal and opposite but act on different objects, so they never cancel.

Balanced forces (resultant zero) mean no acceleration. An unbalanced resultant gives a = F/m.

inertia	the tendency of an object to resist a change in its state of motion
resultant force	the single force left after adding all forces on an object
acceleration	the rate of change of velocity, measured in m/s²
mass	the amount of matter in an object, measured in kilograms
weight	the force of gravity on an object, measured in newtons
equilibrium	the state when the resultant force is zero
free body diagram	a sketch showing all forces on one object as labelled arrows
newton	the SI unit of force; the force to accelerate 1 kg at 1 m/s²
