The transmission
To convert heat energy into mechanical work.
Not after riding a bike, but rather during riding a bike. Your muscles convert chemical energy (a form of potential energy) into mechanical energy to do work.
The friction force converts mechanical energy of the body into heat energy that is released. Work done by mechanical energy=Force x displacement =Heat produced.
mechanical energy-electrical energy-mechanical energy
A motor does not provide energy. It converts electrical energy to mechanical energy. From a circuit standpoint, the motor is considered a load (similar to a resistor). Resistors convert electrical energy to heat energy.
The correct answer is Electric motor. An electric motor is a device used to convert electricity into mechanical energy whereas an electric generator converts mechanical energy into electrical energy.
Hydal power plants convert mechanical energy into electrical energy. Hydal power plants use flowing water as a source of mechanical energy. Electricity generated by flowing water from dams is called hydal power.
Mechanical energy is the sum of kinetic and potential energy in an object that is used to do work.
energy acquird by the objects upon which work is done is known as mechanical energy Mechanical energy is found by adding kinetic energy and potential energy.
No engine is 100% efficient: there is always some loss of energy between input and output.
Mechanical Advantage
the answer is chemical energy
