WebThe velocity of moving objects with respect to other moving or stationary objects is called “relative velocity.”. The relative velocity of an observer B in the rest frame of another … WebRelative motion (speed) is covered at KS3 but not explicitly at KS4. Suggested activities: The importance of relative speed could be investigated with reference to collisions.

WebSpeed of the jet airplane, V A = 500 km/h Speed at which the combustion products are ejected relative to the jet plane, V B – V A = – 1500 km/h (The negative sign indicates that the combustion products move in a direction opposite to that of jet) Speed of combustion products w.r.t. observer on the ground, V B – 500 = – 1500 V B ... WebA swimmer’s speed in the direction of flow of a river is 12 km h-1. Against the direction of flow of the river the swimmer’s speed is 6 km h-1. Calculate the swimmer’s speed in still water and the velocity of the river flow. Solution. Let v s and v r , represent the velocities of the swimmer and river respectively with respect to ground. buddy freddy\u0027s plant city fl buffet price
