Gravity is measured in what is called a Gravimetry and this measures the strength of a gravitational field. The instrument used to measure this is called a gravimeter, and to put it simply it measures the constant acceleration of gravity in a downward direction. Experiments using a gravimeter ha...
What is the meaning of the underlined word "position" in the text?[A] The magnitude of gravity is measured here.[B] G is determined at this position.[C] The rotation angle can't be recorded at this position.[D] The gravity achieved balance.5. What can we learn from this passage?[...
Force is mass times acceleration (F = ma), and in this case the acceleration is g:F = mgExample: how much force to hold an apple with a mass of 0.1 kg? F = mg F = 0.1 kg × 9.8 m/s2 F = 0.98 kg m/s2 Force is measured in Newtons (N) which are the same as kg m/s2...
Specific gravity, more formally known as relative density, is a measure of thedensityof a substance in comparison to the density of water. Forsolidsandliquids, specific gravity is generally measured in relation to water at its densest state (at temperatures of 4 Celsius or 39.2 Fahrenheit), and...
Mass is measured in grams (g) or kilograms (kg) but is NOT a force. The weight of an object is the force caused by gravity pulling down on the mass of an object. It is measured innewtons(N). Weight is measured using a force meter. The bigger the weight attached to the force mete...

φ,where g is measured in meters per second per second at sea level. (1)Chicago has latitude 42°. Find g. (2)Philadelphia has latitude 40°. Find g. (3)Express g in terms of sin φ only, That is, eliminate the double angle....
usual standard is water. The specific gravity of water is 1; if a sample of urine shows a specific gravity of 1.025, this means that the urine is 1.025 times heavier than water. (The normal specific gravity of urine is 1.003–1.030.) Specific gravity is measured by means of a hydrometer...
There're lots of mascons on the moon too, where a mascon's density causes a small increase in the local gravity that can be measured and mapped by orbiting spacecraft. 来源于:听力OFFICIAL35 L6 Researchers notice a gravity anomaly similar to those on the moon. 研究者们注意到了类似于...
Unit16 Gravity Measurment(重力测量)As known from daily experience , the most conspicuous force present on the surface of the Earth is gravity . Gravity is the force that pulls things towards the center of the Earth .Gravity affects almost everything in our lives . From clocks to hydroelectric ...
