EVERYDAY SCIENCE

Detailed explanation-1: -Chemical energy is converted into mechanical energy during muscle contraction.

Detailed explanation-2: -The energy in sunlight is used by plants to make chemicals. These chemicals have some of this energy stored in them as chemical energy. When we or other animals eat the food, we change the chemical energy into mechanical energy of a living, growing, and moving body.

Detailed explanation-3: -During muscle contraction, chemical energy is converted to mechanical energy when ATP is hydrolysed during cross-bridge cycling. This mechanical energy is then distributed and stored in the tissue as the muscle deforms or is used to perform external work.

Detailed explanation-4: -Food supplies a lot of chemical energy that is stored in our body in the form of potential energy which is then converted into mechanical energy when we are doing some activities like walking, running, jumping, pulling, pushing, etc.
