Please use examples like a person is walking on a moving a train. What happens to the velocity of the moving object if the frame reference does not have constant velocity?
In: Physics
Say you’re sitting on a bench. From your perspective a train is moving from left to right.
Say a person is walking on the train from right to left at a constant speed. But the train itself is slowing down. You’ll perceive this person as walking at a normal pace or a slightly fast pace.
Say instead the train is speeding up, you’ll perceive this person as walking at a slow pace.
Say instead the person is walking on the train from left to right at a constant speed. Now, regardless of whether the train is slowing down or speeding up, to u’ll perceive this person as walking at a fast pace. This is because they are going in the same direction as the train.
In all these cases the person is walking at a constant speed but the direction and the speed of the frame of reference, the train, determines your perspective.
