Gravity keeps the moon where it's supposed to be — in orbit. Peepo / Getty Images 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 ...
What Is the Force of Gravity? If you throw a ball up, it will come down again. What makes it come down? The ball comes down because it is pulled or attracted towards the Earth. The Earth exerts a force of attraction on all objects. Objects that are nearer to the Earth are attracted...
"Earth itself would most likely break apart into pieces and float off into space." A similar fate would happen to the Sun. Without the force of gravity to hold it together, the intense pressures at its core would cause it to burst open in an explosion. The same thing would happen to ...
If you turn something around your head on a string(细绳), it goes around in a circle until you let go of the string. Then it flies off in a straight line. ‘Switching off’ gravity would be like letting go of the string. Things not attached to the Earth would fly off in a ...
Load, on the other hand, is often the result of a force, such as gravity, and is typically measured as a weight. 13 When an engineer designs a building, they calculate loads, which are the forces a structure must support. These loads include the weight of the structure itself, known ...
The Force of Gravity:Gravity is a force we're all familiar with. This force pushes us down towards the Earth and prevents us from floating out into space. It's also what holds the gas molecules in our atmosphere, creating a livable space on the surface of the planet....
