The equivalence principle in physics simply explained

The equivalence principle has to do with acceleration.

These are the statements of the equivalence principle

  • The equivalence principle goes back to Galileo Galilei, who had been found experimentally that the body speed regardless of your weight in free fall equal, so fall equally fast. It therefore makes no difference in theory, if you throw a dumbbell or a ping-pong ball from a tall building, in theory should both pay the same below. In practice, there are still distorting factors such as air resistance, and quite apart from that, you should always throw any objects from buildings. They might hurt other people.
  • The basic message of the equivalence principle is that the inertial and gravitational mass of a body, that is equivalent to the same. The heavy mass is based on the weight, ie (for us) of gravity, the inertial mass is that resistance which has to overcome a force to move the body.
  • The principle is also found in Newton's second law again, which is also known as an action principle. It states that more massive a body is, the more energy must be expended to move him. This additional expense required energy corresponds exactly to exert more of attraction, the earth and a heavy body with each other. so balance each other out.

The principle is extended in modern physics

  • In physics, one speaks of a strong equivalence principle. This is mainly for Einstein's theory of relativity is of great importance. Here it is assumed that there may be in a hypothetical space which is subject to no interaction with its environment, no reliable information as to whether a body is in weightlessness or in freefall.
  • A hypothetical homogeneous gravitational field would therefore correspond to a uniform acceleration in a non-curved spacetime, according to the statement made. The experimental physics, it is not yet been able to disprove this theory.
