Instructions and help about Velocity Overview

in this video we're going to talk about relative velocity so when you hear the word relative velocity what do you think of what i think of you're talking about the velocity of an object relative to something else and whenever you want to calculate the relative velocity is basically the difference between two velocities so let's say if we have the variable vba you need to understand what this means what this means is you're talking about the velocity of object b with respect to object a so b is the object that you're considering that's the object in focus a is the reference frame or the frame of reference so how can we calculate v ba how can we find it so this is the velocity of b with respect to a and it's basically the difference between v b and v a now if you see me write v b throughout the remainder of this video what i mean is v b is really the velocity of b with respect to the earth so let's say if a train is moving at 30 miles per hour with respect to earth if you're standing on
