To walk you need to expend mechanical energy in forcing your body forwards through forcing your leg muscles to react with the ground through your feet. Your muscles obtain the energy from chemical reactions within your body, and ultimately from the food you have digested.
The kinetic energy of the athlete can be calculated using the formula KE = 0.5 * m * v^2, where m = mass of the athlete (75 kg) and v = speed. Since the athlete is running at a constant speed over 100m in 10 seconds, we can calculate the speed using distance/time. The speed is 10 m/s. Plugging these values into the formula, the kinetic energy of the athlete is 3750 Joules.
In high jumping, the energy change involves the conversion of potential energy into kinetic energy as the athlete runs and jumps over the bar. The athlete's muscles generate the kinetic energy needed to overcome gravity and propel the body upwards. At the peak of the jump, the kinetic energy is converted back into potential energy before the athlete descends.
Running water produces kinetic energy, which is the energy of motion. This kinetic energy can be harnessed and converted into mechanical energy, usually through the use of turbines in hydroelectric power plants to generate electricity.

The primary form of energy being used by the running boy is kinetic energy, which is the energy associated with movement. This energy is generated by the muscles in the boy's body as they work to move him forward.
yes because if you were running down a hill you are in motion and kinetic energy is in its greatest coming downhill.
Kinetic energy is movement energy. Which mostly comes from chemical energy (food) and we use kinetic energy to do lot of activities,eg walking and running.
