What is the principal difference between the theory of special relativity and the theory of general relativity? Special relativity applies to frames of reference moving at constant velocity, whereas general relativity includes accelerating reference frames.

Newton's theory assumes quantities like space,time ,length,mass etc to be absolute(called classical physics),while in the theory of relativity ,all of the above quantities are relative and changes for different observers(relativistic physics).

One major difference is in the strength of the forces. The gravitational attraction between two electrons is only 8.22*10−37 of the electrostatic force of repulsion at the same separation. However, gravitation usually is concerned with large masses, while any large collection of charges will quickly neutralize.

There is a huge difference between speed and momentum. Speed tells us how much distance an object has covered in a given amount of time. ... Momentum = Mass*Velocity. Speed has no direction specified with it whereas momentum has a direction defined on the basis of the objects velocity.

The main difference between these types of motion is that circular motion is a special case of rotational motion, where the distance between the body's centre of mass and the axis of rotation remains fixed. Rotational motion is based around the idea of rotation of a body about its center of mass.

3 Answers. In a vacuum all light travels the same speed no matter what the wavelength or frequency. Gamma radiation has a smaller wavelength and larger frequency, radio waves a smaller frequency and larger wavelength.

What is the difference between distance and speed? ... Distance is an amount of space (e.g., that has been traversed by an object, between two bodies, or the like). Speed is the rate of change of distance; mathematically, speed is the time derivative of distance.

Special relativity applies to all physical phenomena in the absence of gravity. General relativity explains the law of gravitation and its relation to other forces of nature. It applies to the cosmological and astrophysical realm, including astronomy.

There are two types of observational reference frame: inertial and non-inertial. An inertial frame of reference is defined as one in which all laws of physics take on their simplest form. In special relativity these frames are related by Lorentz transformations, which are parametrized by rapidity.

Einstein's theory of special relativity sets of the speed of light, 186,000 miles per second (300 million meters per second). ... The speed of light is constant, or so textbooks say. But some scientists are exploring the possibility that this cosmic speed limit changes, a consequence of the nature of the vacuum of space.

Objects in space follow the laws or rules of physics, just like objects on Earth do. Things in space have inertia. That is, they travel in a straight line unless there is a force that makes them stop or change. The movement of things in space is influenced by gravity.

The speed of light is the speed electromagnetic waves travel. The speed of light is 3.0 x 108 m/s in space. The speed of light is the same in all matter. The speed of higher frequency light slows down more than lower frequency light in matter.

Speed and frequency are two different things. Speed refers to the distance covered in a set amount of time. In general the speed of light, for example, is 300,000,000 m/s, meaning that every second it travels about 300,000,000 meters! ... Frequency refers to the cycles per set amount (or unit) of time.

The general relativistic effects are defined by the gravitational potential that is the ratio of mass to radius. In particular, the radius of a black hole is proportional to its mass. Stars can be more massive but still as far from becoming black holes, if their radius increases at least as much as their mass.

3 Answers. In general relativity, gravity affects anything with energy. While light doesn't have rest-mass, it still has energy --- and is thus affected by gravity. If you think of gravity as a distortion in space-time (a la general relativity), it doesn't matter what the secondary object is.

The initial speed of an object simply refers to how fast it is moving when it begins its motion (it doesn't take into account whether it is travelling north, south, left, right, etc.). It is a scalar. The initial velocity of an object, on the other hand, has both a magnitude (speed) and a direction (ie: to the left).

In the 20th century, Newton's model was replaced by general relativity where gravity is not a force but the result of the geometry of spacetime. Under general relativity, anti-gravity is impossible except under contrived circumstances.
