Acceleration is produced when a force acts on a mass, the greater the mass, the more force is required to accelerate the object.
Newton's Third Law
All forces come in pairs. The two forces in a pair act on different objects and are equal in strength and opposite in direction.
balanced forces
forces that are equal in size but opposite in direction
unbalanced forces
forces that cause a change in the motion of an object
Example of Newton's First Law
