WebStatic friction prevents sliding. Static friction is the force holding an object in place on an incline, such as the cheese in Figure 1. The friction force points against the direction that the object would slide without friction. Static friction keeps gravity from pulling the cheese down the incline. WebJan 3, 2016 · So overall the energy loss is through friction. On the way, however, a bit of energy is stored in compressed air before getting lost via friction in the air as it re-expands. And finally a combination of compression and friction: With the meteor moving at this speed, there is a lot of heat generated (compression, as well as friction/viscosity).
