Is weight the pull of gravity on matter?
Yes. A useful formula for weight is:weight = mass x gravity ... where gravity is the gravitational acceleration, for example around 9.8 meters/second squared near Earth's surface.
How is gravity useful?
Gravity is a force that keeps things from floating in mid air. Without it you would have been out of the earth by now!! Gravity is a strength deep under the earth (from the inside). Hope this was useful..
Why is friction useful?
friction is useful because without it we wouldn't be able to walk or do anything for that matter. friction lets us grip onto things with the help of gravity
Why is mass a useful property?
Mass has two significant consequences, which are gravity and inertia. Without gravity we would have no planets or stars, since interstellar gas clouds would never condense. And without inertia, it would be really hard to play tennis.
Who was the first scientist to describe how the force of gravity behaved?
Aristotle did the first recorded speculations on the nature of gravity. Speculations by various philosophers continued for centuries. By 1544, experimenters had shown that Aristotles speculations were false. Galileo Galilei did the first mathematical description of gravity at the Earth's surface. Isaac Newton showed that the same force (gravity) that caused objects to fall to the Earth also caused the planets to go around our Sun. Albert Einstein showed that gravity was not EXACTLY a force between two masses (although that is a useful approximation) but a warping of space by each mass.
How is gravity not useful in soccer?
You can't play soccer if there is no gravity in the first place. So, the presumption in the question statement that gravity is not useful in soccer is not valid.
When is gravity useful?
when you are jumping on a trampoline you dont fly into space.
Which two theories would be useful in designing a roller coaster?
gravity and momentum

How could specific gravity be useful in determining the purity of a diamond?
Specific gravity is the same as density, so if anything except diamondis used then the density would be changed

How is science useful in gymnastics?
Science is useful in gymnastics because it contributes to every trick that you may do. For example, the force of gravity affected your balance and performance on every element and equipment in the whole gym centre, AKA; the beam- your sense of balance, the bars and rings- gravity pulls you down, and on the trampoline and floor, you are able to fly through the air(but not for very long)!!!Science is useful in gymnastics because of gravity, surface tension, heat energy, static electricity and friction.
Is mathematics useful in the sciences including physics chemistry and engineering?
Math is very useful in all of those subjects, especially chemistry formulas, physics gravity equations and engineering 3D objects/drawings.
How can a spring be useful?
A Spring is useful in "storing" energy. It is also useful to provide a "measured resistance" to counter-act an opposing force or energy. Or to determine "mass", or gravity expressed as newtons , or plain old lbs or weight. A spring can be useful in many ways. It can reduce shock to components ,vehicles and even bldg's.
How is gravity used for energy?
When pushing something up against the force of gravity, you are making an "energy investment", so to speak. (You require energy to push the object up; this energy can be recovered when the object falls back down.)
