What is a gravimeter?
A gravimeter is a specialized type of accelerometer designed for measuring the local gravitational field of the Earth. In a most basic conception, a gravimeter is simply a highly developed derivation of a scale used for weighing an object. In this way, gravimeters operate on the same principle as any other accelerometer, by measuring acceleration relative to a static basis, but are designed to be far more sensitive than a typical accelerometer in order to measure the minute changes within the Earth's gravity that can happen to due the planet's shape or local geological features.
What scientist would use a spring scale?
A physicist measuring the force of gravity may use a simple balance, one arm of which is acted on by a small mass, and the other arm is acted on by a spring. This is the simplest type of gravimeter, and changes in the degree of balance is proportional to the local gravity. In my country New Zealand, the force of gravity varies by approx 1 part in 1000. This is right at the legal limit for accuracy of measurement for trade purposes, so local variations in gravity are not unimportant.
What is 150 pounds converted to newtons?
Newtons is a measurement of force, and kilograms measures mass. In order to convert between the two you need some form of acceleration. Using Newtons law (F=ma) and assuming you are using gravity on earth, you would multiply 150 kg by 9.81 m/s^2 to get the force in Newtons.
What is a sentence using the word gravimeter?
"The most sensitive gravimeter can measure tiny differences in the Earth's pull."
What does a gravimeter do in paint spraying?
It insures the correct viscosity of the paint to be sprayed.
What is mean by g in mems accelerometer sensor?
i think it is related to gravityit is gravimeter
What is instrumental drift?
Instrumental drift is the systematic time variation of the instrumental zero value. (A small) temporal variation of the zero reading of the gravimeter.
How is the gravity survey caried out today?
The gravity survey is carried out with the use of a gravimeter, which uses a fixed length spring and mass attached to a calibration spring.
Why is the terrain correction always positive?
Nearby topography (hills and valleys) attracts the mass in the gravimeter (valleys are considered to have negative density with respect to the surrounding rocks) and reduces the observed value of gravity. The terrain correction is the calculated effect of this topography and is always positive (a hill pulls up on the mass in the gravimeter and a valley is a mass deficiency).

Is gravitational force constant all over earth?
For the most part, yes; the weight of an object is equal at any point on the Earth as measured by any standard scale. However, using a gravimeter it is possible to detect minute differences in gravitational force. These differences are due to differences in topography or rock density at the site of measurement. For example, a gravimeter will yield a slightly lower gravity measure if read above a granite slab (low density) than it would over a basalt slab (high density), providing that both slabs are at equal altitude and are thick enough to be detected by the gravimeter (often on the order of 10s-100s of meters thick). Measuring gravity is how many features below the ice on Antarctica have been mapped, and is often how oil fields are discovered.
What do vocanologist use to study volcano?
Many different tools are available to study volcanoes. Magnetism is valuable to check whether a rising bolus of magma is coming. Similarly for a gravimeter, or a tilt meter. On Mt Ruapehu, an active volcano in New Zealand, the level of its crater lake is monitored because of previous proven hazard of a lahar.
What words are dirivatives of gravis?
"Gravis" is an adjective from Latin, meaning HEAVY, SERIOUS, IMPORTANT. Some derivatives of it in English can be: - graveless; - gravid; - gravidity; - gravidly; - gravidness; - gravida (pl.: gravidas OR gravidae); - gravimeter; - gravimetric; - gravimetrically; - gravimetry; - gravitate / + d / +ing; - gravitation; - gravitational; - gravitationally; - gravitative; - graviton; - gravity; - gravy (pl.: gravies).
How are volcanoes predicted?
using seismographs, volcanologists can use the data to interpret the vibrations around to volcanos to known signatures of recent activity around volcanos and use this with past experience and data to decipher the liklehood of an eruption or major volcanic lava flow in the near future.
Earth's gravitational constant?
Earths gravitational constant, known as g, as around 9.81 m s-1 .The word around is a tip-off that it is a somewhat inconstant constant. It varies slightly depending on your latitude, longitude, height a.s.l. and the type and extent of the minerals under your feet. This last explains why some geologists carry a handy instrument called a gravimeter.
