When one-dimensional velocities are measured with respect to a common reference frame, we can find relative velocities of objects by subtracting the velocities of the objects. adding velocities of the objects. taking the average velocity of all the objects. pretending that all objects move with the same velocity You are at the bottom of the "up" side of an escalator in a building. Your friend is at the top of the adjacent "down" side. Each of you have a reference frame in which your motion is in the positive direction. Which of the following best describes your relative motion? Each of you sees the other with a negative velocity. You see her with a negative velocity, but she sees you with a positive velocity Each of you sees the other with a positive velocity. You see her with a positive velocity, but she sees you with a negative velocity. As you drive down the interstate eastward (positive), you pass another vehicle (also traveling eastward). Which of the following best describes your relative motions? Relative to you, the passed vehicle has a positive velocity. Relative to the passed vehicle, you have a negative velocity. Relative to you, the passed vehicle has a negative velocity. Relative to the passed vehicle, you have a positive velocity. Relative to you, the passed vehicle has a negative velocity. Relative to the passed vehicle, you also have a negative velocity. Relative to you, the passed vehicle has a positive velocity. Relative to the passed vehicle, you also have a positive velocity.
