Hinge joints allow flexion and extension only. Flexion – bending a joint. This occurs when the angle of a joint decreases. For example, the elbow flexes when performing a biceps curl. The knee flexes ...

A force is a push or a pull. For example, when you push open a door you must apply a force to the door. You also must apply a force to pull open a drawer. You cannot see a force but often you can see ...

Physics is the search for and application of rules that can help us understand and predict the world around us. Central to physics are ideas such as energy, mass, particles and waves. Physics attempts ...
