This principle states that energy cannot be added or subtracted from the original energy of a system. Energy can, however, be transformed, between forms.
Potential energy is stored energy that is related to height. When skaters are at the tops of the ramps, they have the highest amount of potential energy. Kinetic energy is energy of motion. The faster skaters move, the more kinetic energy they have.
Skateboarding has seen an immense growth in popularity over the last several years. What started as a way for surfers to kill time when the waves were not high enough for surfing has turned into an organized, competitive sport that boasts internationally known athletes and a million dollar industry. One way physics comes into play in the halfpipe ...
