Our current science unit on Forces has us thinking about objects around us in many different ways. What is happening when I’m swinging on a swing? What makes a moving object slow down? What has to happen in order for a see-saw to have zero net force (be completely balanced)?

Forces that are equal in size but opposite in direction are called balanced forces. Balanced forces do not cause a change in the motion of objects. Forces that cause a change in motion of objects are called unbalanced forces.
