[Company Sports Equipment Co., Ltd. official website news] You are really good, back to the company's official website, thank you for the high value of the face, but also to read Xiaobian articles, hoping to get your resonance and inspiration! This company brand amusement equipment and outdoor development equipment: suitable for playgrounds, parks, kindergartens, communities, shopping malls and other indoor and outdoor venues, set fitness and entertainment in one, to bring children a different experience! When you are on the swing, the higher the swing, the more its mechanical energy is not conserved, and it can change continuously. So where does this mechanical swing come from? When we are on a swing, if people stand still on a swing, the swing exercise is similar to a swing exercise. When the swing oscillates from the lowest point to the highest point, gravity does negative work, and the kinetic energy of the system is converted into the potential energy of the system. When the swing swings back from the highest point to the lowest point, the potential energy of the system is converted into the kinetic energy of the system. The mechanical energy of the process is conserved and the swing will swing in equal amplitude. If you want to make the swing higher and higher, you must use external forces to swing yourself. There is no way to rely on external forces, and the system cannot obtain energy from the outside world. Only through swinging people themselves and the internal forces of the ropes do their work to transform their internal energy into the mechanical energy of the system, and human internal power can only be achieved by people standing up or down on the swing. However, when the person swings to the equilibrium position, the hands pull the rope forcefully, and the rope pulls people with the reaction force of the same size. This force overcomes people's gravity and causes people to suddenly stand up. People will move upwards at this time. The system's gravitational potential energy increases. At this point, the tangential velocity has not changed, ie, the kinetic energy has not changed, and the mechanical energy of the system increases. When the swing swings slowly from the lowest point to the highest point, in this process, gravity will no longer work negatively, and almost no work will be done. Even positive work can be done. When people rise to the highest point, they stand up quickly. Increase the gravitational potential energy. When the swing swings from the highest point to its lowest point, it slowly squats and lowers its center of gravity. At this time, the position of the center of gravity falls. Gravity still does positive work. In one cycle, gravity always does positive work. In this way, swingers can transform their internal energy into the mechanical energy of the swing. In short, people on the swing should stand up quickly when the swing reaches its lowest point, and then slowly squat, when the swing reaches the highest point, then suddenly stand up, after the highest point and then slowly squat down to the lowest When you suddenly start to stand up and repeat the above action, the swing is higher and higher.
