Newton`s First Law of Motion
... – On the moon, the object would have only one-sixth the weight it has on the earth. This is because the force of gravity on the moon is only one-sixth as strong as it is on the earth – If the object were in a gravity-free region of space, its weight would be zero. Its mass, on the other hand, would ...

Chapter 12 Notes
... Gravity is the weakest universal force, but it is the most effective over long distances. Earth’s gravitational force keeps the moon in a nearly circular orbit. The gravitational pull of the moon on the Earth causes ocean tides. ...

In fact, in the early 1900s before the advent of rockets, many people thought that sending a rocket to the moon was impossible because of the absence of an atmosphere for the rocket to push a ...

... When the net force is zero, there are balanced forces and there is no change in motion. To achieve a net force of zero means that an applied force balances the force of friction so that the combined force acting on the object is zero. (Ex.
