A train moves at 30 mph. A person on the train runs at 10 mph. What does it look like to someone on the ground?

Thank you so much! I was so confused on the relativity to ground when the person is walking sideways, but you just cleared my confusion right up! Thanks Professor.

@@yoprofmatt why for the second case you were considering Pythagoras theorem... Why not not subtract it vectorially, which will give you 20 not 31.

Dear professor! Why we see an object which is in faraway with less velocity than the closer one?

@yoprofmatt Жыл бұрын

Great question. The angle the object subtends across your eye as it moves is how you interpret speed. When the object is farther away, even moving at the same speed, it looks slower because the angle is less. Cheers, Dr. A

Vpe=31.6 mph Vte=30 difference is there. person is standing in same train. So why velocity relative to earth is different??? Sir ans pls

@charliesheen2081 3 жыл бұрын

that's when the person is moving sideways

@jeffreydaclan1035 2 жыл бұрын

velocity is distance in a period of time, a guy walking sideways would generate a longer distance than when he is at rest on a train, a greater distance in same period of time means faster greater velocity
