Exercise Energy : Use exercise energy instrument now!
In order to measure exercise energy, speed must be fixed. In order to minimize frictional resistance of wagon wheel, there is a rail in wheel parts. Speed may vary according to rear guarding speed of the wagon. There is a slide indication point of moving distance measurement. Scale of moving distance of an object and scale of moving distance of wagon(quantity) are separate.
Potential energy, inclined plane experiment may change quantity that the wagon holds by using this instrument, and the quantity of location energy according to the height by adding a weight by adding a weight.
There are various forms of energy: chemical energy, heat, electromagnetic radiation, potential energy (gravitational, electric, elastic, etc.), nuclear energy, rest energy. These can be categorized in two main classes: potential energy and kinetic energy.
Kinetic energy can be best understood by examples that demonstrate how it is transformed to and from other forms of energy.
For example, a cyclist will use chemical energy that was provided by food to accelerate a bicycle to a chosen speed. This speed can be maintained without further work, except to overcome air-resistance and friction. The energy has been converted into kinetic energy – the energy of motion – but the process is not completely efficient and heat is also produced within the cyclist.
In classical mechanics, the kinetic energy of a "point object" (a body so small that its size can be ignored), or a non-rotating rigid body, is given by the equation
where m is the mass and v is the speed of the body. In SI units (used for most modern scientific work), mass is measured in kilograms, speed in metres per second, and the resulting kinetic energy is in joules.
Potential energy is the capacity for doing work that a body possesses because of its position or condition. For example, a stone resting on the edge of a cliff has potential energy due to its position in the earth's gravitational field. If it falls, the force of gravity (which is equal to the stone's weight) will act on it until it strikes the ground; the stone's potential energy is equal to its weight times the distance it can fall. A charge in an electric field also has potential energy because of its position; a stretched spring has potential energy because of its condition.
Difference between Kinetic Energy and Potential Energy.
The difference between kinetic energy and potential energy, and the conversion of one to the other, is demonstrated by the falling of a rock from a cliff, when its energy of position is changed to energy of motion. Another example is provided in the movements of a simple pendulum. As the suspended body moves upward in its swing, its kinetic energy is continuously being changed into potential energy; the higher it goes the greater becomes the energy that it owes to its position. At the top of the swing the change from kinetic to potential energy is complete, and in the course of the downward motion that follows the potential energy is in turn converted to kinetic energy.
