•A traveler, moving at the speed of light, would circumnavigate the equator approximately 7.5 times in one second. By comparison, a traveler in a jet aircraft, moving at a ground speed of 500 mph, would cross JUST the continental U.S. once in 4 hours.

• It takes 499.0 seconds (8 min) for light to travel from the Sun to the Earth

Question #7•How fast does hair grow?

•Average 1.25 centimeters or 0.5 inches per month

•Depends on age and health

Question #8•Is motion relative?•Yes or No?

Yes• All things are in motion. You may be perfectly still yet the earth

is spinning on its axis and orbiting the sun. The sun orbits the center of the galaxy, our galaxy and Andromeda are moving toward one another, most of the other galaxies are moving away.

So to measure motion in a meaningful way, we measure it relative to the observer or another object we consider not to be moving. When you pass a car on the highway moving in the same direction, you may be going 70mph, and the other car 65mph. But your speed relative to the other car is 5mph. When the shuttle docks with the space station the two orbiting objects approach one another at a very slow speed relative to one another, but both are orbiting at 17,000mph relative to the surface of the earth.
