• It is a push or pull on an object that produces acceleration in the body on which it acts.
• A force of one Newton produces an acceleration of 1 m/s² on an object of mass 1 kg. 1 N = 1 kg m/s²
• When forces acting on a body from the opposite direction do not change the state of rest or of motion of an object, such forces are called balanced forces.
• The rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of the force.
