... • When a system does work, such as an engine raising a weight, energy is transferred from the system to the surroundings. Energy is also transferred when a system releases heat, as in a combustion. A system with a high internal energy can do a lot of work or provide a lot of heat to the surroundings ...

... Everyday we practice many forms of physics without giving them any second thought. Perhaps the most used everyday form of physics used by people is ambulation, also known as bipedal locomotion, or walking. The act of walking consists of numerous physical concepts, including rotational inertia, accel ...
