Consider the simulation results below of the block sliding on a smooth incline. These results show that there is a complicated exchange in energy among the spring potential, the gravitational ...

Very large hail is the main concern, but strong wind gusts and a stray tornado are possible with the strongest storms too ...

Forces may change the shape of an object. An elastic object, such as a spring, stores elastic potential energy when stretched or squashed. The extension of an elastic object is directly ...
