The states of motion and rest are relative. Explain.
How is average velocity different from instantaneou
Answers
Answer:
The relative velocity is the velocity of an object or observer B in the rest frame of another object or the observer A. The general formula of velocity is :
Velocity of B relative to A is = v⃗ b−v⃗ a
This is the only formula that describes the concept of relative velocity. When two objects are moving in the same direction, then
v⃗ ab=v⃗ a+v⃗ b
When two objects are moving in the opposite direction, then
v⃗ ab=v⃗ a−v⃗ b
Lets us understand the concept of relative velocity with this example.
Consider two trains moving with same speed and in the same direction. Even if both the trains are in motion with respect to buildings, trees along the two sides of the track, yet to the observer of the train, the other train does not seem to be moving at all. the velocity of the train appears to be zero.
Suppose you are in a car moving at 50mph.The 50 mph is your relative velocity as compared to the surface of the earth.At the same time if I am sitting next to you your relative velocity compared to me is zero. If we were on a bus and you walked forward at 1 mph, your relative velocity on the earth would be 51 mph and your relative velocity compared to me would be 1 mph. Relative velocity is simply any objects speed compared to any other object regardless of its speed.
