Mechanical energy changes into chemical energy as the kinetic energy from motion creates reactions in the surrounding air.
Mechanical energy changes into chemical energy as the kinetic energy from motion creates reactions in the surrounding air.
Mechanical energy changes into thermal energy because the energy from motion creates heat in the air around the runner.
Mechanical energy changes into thermal energy because the energy from motion creates heat in the air around the runner.
Chemical energy changes into mechanical energy because energy from digestion of food provides energy for the runner’s motion.
Chemical energy changes into mechanical energy because energy from digestion of food provides energy for the runner’s motion.
Thermal energy changes into mechanical energy because heat provides energy for motion.
Chemical energy changes into mechanical energy because energy from digestion of food provides energy for the runner's motion.
The main energy conversion that occurs when a woman runs is that chemical energy changes into mechanical energy because energy from the digestion of food provides energy for the runner's motion.
The correct answer is: Chemical energy changes into mechanical energy because energy from digestion of food provides energy for the runner’s motion.
To answer this question, you need to understand the concept of energy conversion. Energy can be converted from one form to another. In this case, the energy conversion is happening in a woman running.
When a person is running, they need energy to move their muscles and perform the motion. In this case, the energy is obtained from the digestion of food. When we eat food, our body breaks down the food into smaller molecules, such as glucose, which can be used for energy.
This energy from the digestion of food is in the form of chemical energy. Chemical energy is stored in food molecules and can be released when these molecules undergo chemical reactions, such as during the process of cellular respiration.
As the woman runs, the chemical energy stored in her body is converted into mechanical energy. This conversion happens in our muscles, where the chemical energy from the food is used to generate the force and movement required for running.
Therefore, the main energy conversion occurring in this situation is that chemical energy changes into mechanical energy because the energy from digestion of food provides energy for the runner's motion.
