Gravity Gravity constantly pulls things down when it enters the earth’s atmosphere. Why does earth have a gravitational pull? Earth’s have a gravitational pull that keeps us on the ground so we won’t float off in space. What is the earth’s atmosphere made of? earth’s atmosphere has...
"Switching off" gravity would be like letting go of the string. Things not attached to the Earth would fly off in a straight line. People in buildings would suddenly shoot upwards at a great speed until they hit the ceiling. Most things outside would fly off into space. ...

Though photon have no mass, why gravity attracts it? What is mean by the specific gravity? Who invented gravity force? Why can you exert greater force on the pedals of a bicycle if you pull up on handlebars? Why is the earth rotating itself? Why and how do things move if Newton's ...

When in free-fall, all that the ball “knows” is that there’s some gravity around. When it hits the ground it’s as surprised as anything else. The path that any tossed or falling object follows is just the tip of averyelliptical orbital path that, if the Earth’s mass were ...

Male professor: Well, one thing that's hard to do is to sort of see things from the perspective of someone who's hearing that theory for the first time. I mean today we tend to assume that the moment the heliocentric theory was laid out, the idea that the Sun, not the Earth, was...
