If heat speeds up molecules, why dont we run faster in the sun?

Question

This has been in my mind science forever please awnser

Answer 1

One answer already given, "Heat speeds up the *random motions* of molecules, not their bulk motions. In other words, it gets the molecules in your body *vibrating* faster, but that does nothing for your running ability", is correct.  But also your body regulates its own temperature, so your body isn't much warmer when you're running in the sun than when you're running in the shade or in the dark.

Answer 2

We're a little bigger than molecules. It takes very little heat to get them going.

Put enough heat on a person and they will move pretty fast.

Answer 3

Heat speeds up the *random motions* of molecules, not their bulk motions. In other words, it gets the molecules in your body *vibrating* faster, but that does nothing for your running ability.

Answer 4

You do..basic physiology..you don,t run faster like jogging duh..... but the body revs up... you start to sweat.. you get thirsty.. you loose wieght.. etc etc..this is antomy &phys 101

Answer 5

Also, when people talk about increases in kinetic energy, they mean lots of difference.  60 - 100 degrees isn't much when it comes to quantum mechanics and molecular motion.

Answer 6

Eerrrrrrrrrrrrrrrrrrrrrr.

Answer 7

All molecules moves to all different directions not to one specific direction.

A body, in order to move, must all of its molecules to move to the same direction.

So a body in the sun will not move faster but its molecules will.

Answer 8

heh - because we would melt and burn first

:)

Our molecules would bounce around pretty fast after that though.

edit: I guess you didn't mean INside the sun. lol!
