If The Earth Spins 66000mph and an aeroplane is travelling 500mph OPPOSITE to the direction the earth is spinning and i am walkling 2mph in the SAME direction as the earth is spinning. Doesn't that mean im walking 66002mph and the aeroplane is only travelling 65500mph... Surely that means im faster than the plane? Lol sounds complicated. I worked this out when i was walking my dog with my dad and sister and saw an aeroplane overhead :D

i like all your answer but aren't i still partly right??

Ok i sort of understand the relativity part : everyone and everything else on earth sees me walking 2mph but from space someone watching me would think i am quicker than the plane? But im still partly right! :D

Aww wish i could choose everyone as the best answer : ( all your answers have been great! Many Thanks!

The actual speed you are travelling is measured relative to other objects. You are travelling at 2mph relative to the earth. The plane would still be travelling at 500mph relative to the earth, regardless of direction. It is just that you are going one way and the plane the other. Though if an astronaut were to observe you from space. it would appear to him that you were going faster than the plane, as the earth would be rotating in one direction from his viewpoint. Imagine if you were actually in the plane walking to the front at 2mph. Relative to the earth below you would be going at 502mph, but relative to everyone else in the plane you would be still only going at 2mph. Hope this helps.

Speeds are relative. You are moving over 66002mph compared to a stationary object in space. However, compared to objects on the surface you are only moving 2mph. The atmosphere is also moving on average at the same speed as the ground, so the plane is moving 500mph through the air and relative to the ground, but it is moving 65500mph in the opposite direction compared to a stationary object in space.

The earth revolves around the sun at 66.000 MPH, relative to the sun the plane is moving at 65.500 MPH, if you are walking at 2MPH in the direction of the Earth's rotation that means that you walking towards the plane's rear therefore you are moving, relative to the sun at a speed of 65.498 MPH. Relative to the Earth's surface the plane is moving at 500 MPH if its ground speed is the same as it's air speed and you are moving, relative to the Earth's surface at a speed 498 MPH. Phew..

Don't be daft. Your speed references for both yourself and the plane are both relative to points on the earth which are not moving relative to each other. You would be walking towards the plane at 2mph and the plane is moving towards you at 500mph meaning a combined speed of 502mph.

Sorry old chap but, the Earth's rotation is only about 26,000mph.
As the atmosphere is rotating with the earth, the plane and you are travelling at the speeds given in your question, relative to the ground. In your question you may well ask if a hot air balloon which is stationary in relation to the ground is actually travelling at 26,000mph.

Relative to a stationary astronaut in space your velocity is 66002mph due to combination of walking speed and earth's speed. Strictly though we should consider earth's speed around the sun, precession and all its other speeds.The aeroplanes speed relative to someone in space would be 65500 mph in the same direction as the spinning.

I'm sorry to burst your bubble but speed is measured by distance across the worlds surface as opposed to the entire distance becuase otherwise any speed ever taken would be faster than the speed of the earth. Although if you weren't applying normal speed rules then this would be correct. Hope this helps :) and by the way you must be very intelligent to have worked this out whilst walking your dog just with knowledge from your own brain. :D

Why 66000mph? It spins at about 1000mph. Wouldnt that make a simpler question?
To make that answer correct, you would have to be at the very centre of the Earth, not spinning with the Earth and following the Earths path through space exactly.

lol no because your basicly going one the same fixed point.
Assume your at a point the furthest you can be from teh place you want to be. the plane is with you. you walk following the rotation of the earth and the planet flys to other way (aginst). yours saying that the plane would end up behind the point at which it started becaus eits moving -65500 pm in the idea of the earth which would make it impossalbe to move west from any given point.

True, but that is your apparent speed of motion/movement from an observer at the center of the earth only.
