What is the relative velocity of two moving objects zero?

Relative velocity refers to two moving bodies; it is not just the difference in the velocities. is the difference in the speeds of body A and body B. If two bodies are moving in the same direction at the same velocity, then the relative velocity will be zero.

What is the relative velocity of two moving objects?

Relative velocity is the time rate of change of relative position of one object with respect to another. If two objects are moving in same direction, the magnitude of relative velocity of one object with respect to another is equal to difference in magnitude of two velocities.

When two photons moving away from each other their relative velocity will be?

As the rest mass of a photon is zero, it always moves with the speed of light. And as we know that no material body can ever travel with a speed more than the speed of light in vacuum. Now as the two photons move with speed c of light opposite to each other, their relative velocity is also c.

Which condition does relative velocity become zero?

The relative velocity becomes zero when the two bodies move in the same direction with the same velocity.

Can an object have zero acceleration but non zero velocity How?

Acceleration is the rate of change of velocity with time. As the velocity is a constant value over all the values of time, the rate of change of velocity is thus zero. So, acceleration is zero. So, zero acceleration and non zero velocity are possible for particles moving with constant velocity.

How is the motion of two objects relative to each other described?

How is the motion of two objects relative to each other described? Relative Motion The motion of two objects in space is relative to some defined point of reference. How can an object’s momentum be calculated?

Which of the following is postulate of special theory of relativity?

1. Principle of Relativity – All the laws of physics are the same in all inertial reference frames. 2. The speed of light in a vacuum is the same (3.0 x108 m/s) in all inertial reference frames regardless of the motion of the observer or source.

What is the speed of light in special relativity?

Special relativity, developed by Albert Einstein, applies to situations where objects are moving very quickly, at speeds near the speed of light. Generally, you should account for relativistic effects when speeds are higher than 1 / 10th of the speed of light.

What is the relative velocity of a spaceship on another planet?

If the person on the Earth sees the spaceship moving at 0.95c, the observer on the spaceship agrees that the Earth is moving at 0.95c with respect to the spaceship (and because the other planet is not moving relative to the Earth), everyone’s in agreement that the relative velocity between the spaceship and planet is 0.95c.

What are the defining features of special relativity?

A defining feature of special relativity is the replacement of the Galilean transformations of Newtonian mechanics with the Lorentz transformations. Time and space cannot be defined separately from each other (as was earlier thought to be the case).

What are inertial frames of reference in special relativity?

Frames of reference. Special relativity deals with observers moving at constant velocity; this is a lot easier than general relativity, in which observers can accelerate with respect to each other. Note that frames of reference where the velocity is constant are known is inertial frames.
