6 FAQs about [Why don t bicycles use mechanical energy storage]
What type of energy does a bicycle use?
When you ride a bicycle, several things happen that require energy and it’s transformation. You pedaling the bike is transforming chemical energy, supplied by the breakdown of the food you eat, into mechanical energy to turn the pedals. The chemical energy is potential and the mechanical energy is kinetic.
How did a bicycle get its potential energy?
The bicycle got its potential energy (energy due to position related to gravity) by the rider using metabolic energy to move the pedals. The pedals used mechanical energy to move the chain, which moved the wheels. What is an example of electrical energy to mechanical energy?
What are the advantages of a bicycle?
