This week in class we talked about work and energy. Work is defined as when a force acts on a body, and there is a displacement of the point of application in the direction of the force. Energy is defined as a property of objects, transferable through interactions, which can't be created nor destroyed. To demonstrate work and energy in the aspect of sports I did a bunch of lifting exercises. These exercises include leg press, arm curls, bench press, and sitting rows. My legs were the strongest muscle group and my arms were the weakest muscle group in my body. The force my legs put on the weight was 1,000.62 N, the work my legs did was 330.2 J and the power my legs produced was 275.16 W.
