what do you mean by along some axisDoc Al said:If the velocity of B relative to A is +10 m/s along some axis, then the velocity of A relative to B will be -10 m/s.
my_wan said:Yes, as Doc has said. Both A and B can consider their own velocity to be zero. They both consider the other to be the one going 10 m/s. There is no law of physics that allows you to make an absolute distinction between who is moving and who is not.
A velocity such as -10 m/s only makes sense with respect to some direction.q2501 said:what do you mean by along some axis
Relative velocity is the velocity of an object or observer in relation to another object or observer. It takes into account the motion of both objects and their respective velocities.
Relative velocity is calculated by subtracting the velocity of one object from the velocity of the other object. This can be done using vector addition or by using the formula: Vrel = V1 - V2, where Vrel is the relative velocity, V1 is the velocity of the first object, and V2 is the velocity of the second object.
Relative velocity is important because it allows us to understand the motion of objects in relation to each other. It is particularly useful in situations where two objects are moving in different directions or at different speeds.
An example of relative velocity is a car traveling at 50 mph on a highway passing another car traveling at 60 mph. In this scenario, the relative velocity between the two cars is 10 mph.
The theory of relativity states that the laws of physics are the same for all observers in uniform motion. This means that relative velocity plays a crucial role in the theory, as it allows us to understand and predict the motion of objects from different reference frames.
