WebFeb 6, 2024 · The relative motion is calculated as: (4.5.1) A V B = V B − V A. Note that you subtract the velocity of the fixed plate from the moving plate. Similarly, we can reverse which plate is being held fixed and hold plate B fixed. Then: (4.5.2) B V A = V A − V B. gives the velocity of plate A relative to plate B.

WebRelative speed is the speed of a moving body in relation to another.The word “Relative” can be simplified as “in comparison with”. When two bodies are moving in the same direction, their difference is used to calculate their relative speed. When two bodies are moving in opposite directions, however, the relative speed is derived by summing their speeds. WebThe velocity of an object is the time rate of change of its position. Velocity is a specification of an object's speed and direction of motion (e.g. 20 m/s to the south). In everyday use and in kinematics, the speed of an object is the magnitude of its velocity (the rate of change of its position) - scalar.
