We have all experienced the force of gravity. It is what happens to you when you jump up into the air. Disappointingly, we tend to fall right back down to the ground. But what if we could switch gravity off? What will happen if the gravity vanishes? Buckey, an astronomer, says that...
Force of GravityThe force of gravity between two objects is determined by the masses of the objects and the distance between them. The force of gravity (F) is given by the formula:F=Gm1m2r2, where G is the gravitational constant (6.67×10−11 Nm2/kg2)...
What is the speed of gravity on Earth? What is the difference between a moon and a planet? If the mass of Uranus is 8.681 10 25 kg and the radius of Uranus is 2.556 10 7 m, what is the acceleration due to gravity on Uranus?
Gravity is a force that we experience every day, yet it remains somewhat of a mystery. It's the reason we stay grounded on Earth and why objects fall when dropped. Although there are several theories attempting to explain gravity, scientists still don't completely understand it. In this arti...

Without Gravity, the muscles in your body begin to waste away as there is nothing to "motivate" the muscle. To compensate for zero Gravity, astronauts exercise daily to counter the damaging effects. Escape Velocity Escape velocity is the speed at which an object, such as a rocket, must ...
We take a look at what would happen to the human body if it could travel at the speed of light.
