Help! Please give me a nice answer. Do not make it a very complicated answer. (for example, do not say "dreftuopo 734E715I" even though I do not know what it means. And please, if you don't know, don't answer.)

A gravimeter is a device designed to measure the local gravitational field. Also sometimes called a gravitometer, a gravimeter is a type of accelerometer. According to the equivalence principle of Albert Einstein, the effects of a gravitational field are rigorously equivalent to acceleration. Therefore, gravimeters are susceptible to vibration which causes small, oscillatory accelerations. This is counteracted by integral vibration isolation and signal processing.

A stop watch and a known distance ;-)
you can find the acceleration of gravity by the following formula:
a = 2(x - Vt) / t^2
where a is the acceleration of gravity, x is the final position, V is the initial velocity, and t is the time it takes to hit the ground.
For example, if you had a ball that was 10 meters high, and it took one second to hit the ground, the acceleration of gravity would be 10m/s^2

An apple indicates when it falls, that gravity exists. I discovered that in a book. Perhaps if you read on (which I didn't) it will tell you more about it?

A scale measures gravity.
It tells you how much force (in pounds or kilograms) that the earth is exerting on whatever you place upon the scale.

The dreftuopo 734E715I
No, really...it's a gravitometer.
(Sounds good,anyway...)
