(a not very accurate representation of) NEWTON'S LAWS of MOTION: Change the sliders... "Newton's laws of motion are three physical laws that describe the relationship between the motion of an object and the forces acting on it. These laws [] provide the basis for Newtonian mechanics." (Wikipedia) Newton's first law states that something will remain at rest or in motion unless acted on by an unbalanced force (such as friction). Newton's second law shows the equation F=ma (force = mass*acceleration). [I did not include mass in this simulation as all objects are the same size]. Newton's third law states that every action has an equal and opposite reaction.
