What levers are in the human body? Biomechanics: Lever Systems in the Body The gastrocnemius muscle. The greater the ratio of the effort arm to the load arm, the more efficient the lever system is (i.e. the easier it is to move the load). The atlanto-occipital joint as a first class lever. The elbow joint […]

What light Cannot cause skin cancer?
What light Cannot cause skin cancer? Most skin cancers are caused by exposure to ultraviolet (UV) light. When you don’t protect your skin, UV rays from sunlight or tanning beds can damage your skin’s DNA. When the DNA is altered, it can’t properly control skin cell growth, leading to cancer. Can UV LED lights cause […]

How do athletes get energy?
How do athletes get energy? Carbohydrates or “carbs” (found in pasta, bread, cereal, rice, grains, potatoes, fruit, vegetables, milk, yogurt, etc.) are especially important for athletes because they supply the body with glucose for energy. Extra glucose is stored in the muscles and liver as glycogen, your energy reserve. How do I get energy to […]
How can you tell if you see ultraviolet light?
How can you tell if you see ultraviolet light? By definition, ultraviolet light is ‘beyond violet light’ and the visible spectrum that can be detected by the human eye. It cannot, therefore, be seen directly. Detectors that are sensitive to UV convert it into a form that we can see. In this scenario, however, UV […]

Why does metal heat up fast?
Why does metal heat up fast? Why do metals conduct heat so well? The electrons in metal are delocalised electrons and are free moving electrons so when they gain energy (heat) they vibrate more quickly and can move around, this means that they can pass on the energy more quickly. Does glass or metal heat […]
