Example:
A bicycle tire pump uses mechanical energy (your body) and converts it into pneumatic energy (air out of the hose).
how do we convert wind energy into mechanical energy
No, an electric motor does not convert chemical energy to mechanical energy. Electric motors convert electrical energy into mechanical energy by using electromagnetic fields to create motion.
wave to pneumatic energy: 50%-40% pneumatic to mechanical energy (turbine's shaft): 30%-20% mechanical to electrical power: 95%-90% OWC efficiency: 15%-7%
Mechanical, hydraulic and pneumatic are the main ones.
No, muscles convert chemical energy (ATP) into mechanical energy to generate force and movement. They cannot directly convert mechanical energy back into chemical energy.
Motors convert electrical energy to mechanical energy. Generators transfer mechanical energy to electrical energy.
A motor convert electrical energy to mechanical energy.
Yes, examples are steam turbines, locomotive, hydraulic turbines, etc.
No
By burning
No. There are, indeed, ways to convert mechanical energy into electrical energy, but a battery is not usually designed to do this. You can convert mechanical energy to electrical energy by another device, but the battery itself has to be charged by electricity.
Generators are similar to motors in that they both involve the conversion of energy, but generators convert mechanical energy into electrical energy, whereas motors convert electrical energy into mechanical energy.
