If you were on a bus and?

Question

you ran backwards traveling at the same speed the bus is, would you be going at 0mph?

If you were on a bus and Jumpped, would you land in the same place you jumpped from in the bus

Answer 1

In the first case, you would run into the back of the bus very quickly--ouch!!

In the second case, yes would land in the same place, because you are going the same speed as the bus.

Answer 2

If you ran backwards traveling at the same speed the bus is, then you would be moving at the speed you're running at, but not moving anywhere. You also might hit the back of the bus...   not good. If you jumped, yes you would land in the same spot you jumped at in the bus because you are'nt chaning height, therefore gravity wouldn't pull you back to another spot on the bus's floor

Answer 3

Yup.  You got it right.  

Now here's a cool railroad machine that really uses that idea.

The machine moves forward at 2 MPH.  Inside the machine is a work-head on a little track.  The work-head leaps forward, then moves backward at 2 mph so it's going 0 mph.  It drops down and tamps the railroad tie (pushes the rocks under it).   Then it leaps forward to the next tie and does it again!   The machine just keeps crawling along. Genius.  Much faster than starting and stopping the machine every tie!

Answer 4

All motion has to be expressed as "relative to".  Running backwards in the bus, you're moving relative to the other passengers, but not moving relative to a bystander watching from outside.  Jumping up and down, you're going straight up and down relative to the bus and others in it, but moving in an arc relative to the outside.  All of this is also related to earth's 25,000mph spin, our movement around the sun, the sun's trip across the galaxy, and the spin of the galaxy, and maybe even more.
