Kinetic Energy Capabilities And Advantages
Kinetic energy is defined as the impulse needed to accelerate a body of a given mass from rest to its stated speed. This body maintains its kinetic energy unless its speed changes.
The speed and then the kinetic energy of a single object is relative, meaning that it can take any non- negative value, by choosing an appropriate inertial frame for reference. For example, a bullet passing a certain observer has kinetic energy in the frame of reference of this perceiver. The same bullet can be stationary from the point of view of an observer moving in the same direction and with the same speed as the bullet, having zero kinetic energy.
As a conclusion, every item that moves has kinetic energy, which represents the energy of motion. The energy prior to an object movement is called potential energy. As the object moves( example with the bullet) the potential energy is converted into kinetic energy.
The most important Capabilities And Advantages of Kinetic Energy are:
- The kinetic energy it’s an abundant source of energy : since every object that has movement possess kinetic energy, it is one of the most rich energy sources in the whole world. Different civilizations brought under control and put to use kinetic energy for centuries, including using wind turbines to create electricity and water wheels to power boats. An important application of kinetic energy is when electrons move in a medium, creating electrical energy. Any force used to create motion, no matter how large or small it is, creates kinetic energy.
- Kinetic weapons are better than energy weapons: they have the ability to use indirect fire beyond normal visual range. Another important advantage is that they can always accelerate themselves, compared to energy weapons who will always need a some form of sender or emmiter.
It can be converted: For example, this energy in a moving cyclist and a bicycle can be converted to other forms of energy. Let’s say the cyclist will encounter a hill just high enough to coast up, so that the bicycle will come to a complete stop at the top of that hill. All the kinetic energy has now been converted to gravitational potential energy that will be freed by freewheeling down the hill. Since some of the energy has been lost due to friction, it will never regains all of its speed without some extra pedaling. So the energy is not completely destroyed; it has just been converted to another form of energy due to friction.
Another advantage is that kinetic energy can be passed from one object to another: for example, in billiard, the player enforces kinetic energy on the cue ball by hitting it with the cue stick. If the cue ball clashes with another ball, it will slow down and also will allow the ball it collided with to speed up to a certain speed as the kinetic energy is passed on to it. These are elastic collisions, in which kinetic energy is preserved. In inelastic collisions, kinetic energy is dispersed in various forms of energy, such as sound, binding energy and heat.
The Kinetic Energy is one of the most important type of energies today, with lots of Capabilities And Advantages.
