Kinetic energy in physics
Hardly any other formula from physics is as well known as Einstein's formula E = m * c². The kinetic energy is similarly fundamental with the formula T = 1/2 * m * v².
That's energy in physics
- energy is one of the basic quantities in the physics, the chemistry, the biology but also the business. In physics, kinetic energy, potential energy and thermal energy play a role. Its SI unit is joule.
- In physics, kinetic energy, potential energy and thermal energy play a role. The various forms of energy can be converted into one another without restriction.
- In his theory of relativity, Einstein linked the concept of energy inseparably with mass. From this he developed the formula E = m * c². That is, the energy is equal to the mass multiplied by the square of the speed of light.
That is the kinetic energy
- In physics, kinetic energy is also referred to as kinetic energy. This comes from the Greek kinesis, which translated means movement.
- The formula for calculating the kinetic energy is T = 1/2 * m * v². T stands for the energy, m is the mass of the moving body and v is the speed.
- Assume that the total amount of energy always stays the same. Now take a ball of mass m lying on a cupboard. This sphere has the potential energy as it is attracted to the earth's gravitational field.
- If the ball falls from the cupboard, it loses height and thus potential energy. This energy is converted into kinetic energy. The longer the fall, the lower the altitude and thus the potential energy, but the greater the speed and kinetic energy. The mass stays the same.
Use the physics formula correctly for kinetic energy - that's how it's done
In principle, the formula for the kinetic energy can be found in any collection of formulas ...
