What is equivalence principle?
equivalence principle, fundamental law of physics that states that gravitational and inertial forces are of a similar nature and often indistinguishable.
What is an example of the equivalence principle?
Example of Equivalence Principle Imagine you are standing in an elevator or, precisely, is something inside which looks very similar to an elevator cabin. You are isolated from the outer world. Under these circumstances, if you take an object and drop it, it falls and reaches the floor/base.
What does Einstein’s equivalence principle say?
The equivalence principle, a crucial part of Einstein’s general relativity theory, states that the gravitational force experienced in any small region of space-time is the same as the pseudo-force experienced by an observer in an accelerated frame of reference.
What are the consequences of the equivalence principle?
An immediate consequence of the equivalence principle is that gravity bends light. To visualize why this is true imagine a photon crossing the elevator accelerating into space. As the photon crosses the elevator, the floor is accelerated upward and the photon appears to fall downward.
What did Einstein think was inside a black hole?
Black holes are regions of spacetime where gravity’s pull is so strong that nothing, not even light, can escape from being dragged in and “eaten.” Einstein’s theory of general relativity predicted the existence of black holes and that, no matter what such an object “eats,” black holes are characterized only by their …
What is the first principle of Einstein’s theory of relativity?
The Principle of Relativity. The first principle, the principle of relativity, says something about all the laws of physics. To state the principle, we must first express those laws in a particular way, that is, in terms of the quantities defined within an inertial frame of reference.
What are the 3 basic laws of physics?
Three Laws of Motion
- First Rule: An object will remain at rest or in a uniform state of motion unless that state is changed by an external force.
- Second Rule: Force is equal to the change in momentum (mass times velocity) over time.
- Third Rule: For every action in nature there is an equal and opposite reaction.
What does principle of equivalence mean?
equivalence principle, fundamental law of physics that states that gravitational and inertial forces are of a similar nature and often indistinguishable. In the Newtonian form it asserts, in effect, that, within a windowless laboratory freely falling in a uniform gravitational field, experimenters would be unaware that the laboratory is in a state of nonuniform motion.
What is meant by principle of equivalance?
G is the universal gravitational constant

What was Einstein’s principle of equivalence?
Einstein’s Theory Of Gravitation: Principle Of Equivalence; Einstein wondered why inertial mass should be proportional to gravitational mass.
