Summary: When playing football, part of the chemical energy of the human body is converted into the kinetic energy of the footballChemistry, machinery, people do work on the football. When people kick the foot
When playing Kinetic energy of playing football  converted into kinetic energy of football by doing workfootball, part of the chemical energy of the human body is converted into the kinetic energy of the football
Chemistry, machinery, people do work on the football. When people kick the football with their feet, people consume chemical energy and convert it into kinetic energy of the football by doing workIt can convert the kinetic energy of football into electric energy when playing football
It can be seen from the meaning of the topic that the football generator can generate electricity. It is a device that uses the principle of electromagnetic induction to charge; A. The figure shows that a part of the conductor of the closed circuit can generate induced current by cutting the magnetic induction linKinetic energy of playing football  converted into kinetic energy of football by doing workeSeeking the mechanical energy of playing football
The work yoKinetic energy of playing football  converted into kinetic energy of football by doing worku can do for football is half MV square At point a, the mechanical energy of the football is half MV squared minus mg h. The kinetic energy of the football at point B is half MV squared minus mg H
What force do people exert when playing football
Muscle strength is also available. After eating all day and exercising, your muscles will be strong under your exercise. Athletes are not vegetarianAfter a person plays football, he stops for a period of time because football has momentum
This problem is more standard to fill in inertia. Inertia is an attribute of an object, which refers to the property that an object keeps its motion state unchanged It is only related to the mass of the object. The greater the mass, the greater the inertia. Kinetic energy is a kind of motion energy possessed by an object in motionThe football you play has kinetic energy
A football flying in the air has speed, so it has kinetic energy; It has height, so it has gravitational potential energy; Mechanical energy and gravitational potential energy are collectively referred to as mechanical energy, so C
Kinetic energy theorem kicking football to high altitude
Test site a: Special Topic: application of kinetic energy theorem. Analysis: Research on the process of football from players' kicking out to flying into the goal. Some players' work on football and gravity workThe theorem of kinetic energy in playing football is elasticity neglected in doing work
Of course, for example, a 200N kicking ball can achieve a speed of 5m per second and then roll for 10m. This is the kinetic energy theorem. The work done by people on the ball is equal to the kinetic energy increment of the ball. However, at this time, the ball only receives gravity, support and frictionConservation of energy in playing football
3 is wrong. Energy cannot disappear and can only be transformed into other forms of energy. Personally, I think aKinetic energy of players playing football
B the original statiKinetic energy of playing football  converted into kinetic energy of football by doing workc football gets 100 J of kinetic energy, which means that the players have done 100 J of work on the football in the process of kicking the ball, and 100 J of physical energy (chemical energy) has been converted into the kinetic energy of the football. At the same time, the players have to consume some additional physical energy due to their intense exercise in the process of kicking the ball. Therefore, during the process of kicking the ball, they have to exercise
