Concept explainers
To identify: The source of mechanical energy of bike.
Explanation of Solution
Introduction:
According to the law of conservation of energy, the energy can neither be constructed nor be destroyed but it canexist in different forms.
There are different forms of energy available in the universe. The sun rays contain energy in the form of heat and light. Petrol and food contain energy in the form of chemical energy. When one moves on the road, then chemical energy which one gets from food is converted into kinetic energy.
This way the energy is converted from one form to another.
Initially, rider fills the tank of bike with petrol or diesel and then turns on the bike. In this process the chemical energy of petrol is converted into the mechanical energy with the help of engine of the bike. It is found that the conversion of chemical energy of petrol to mechanical energy is not
Conclusion:
Thus, the chemical energy of bike from petrol/diesel is converted to mechanical energy with the help of engine.
