Is gravity a force field?
In its original concept, gravity was a force between point masses. In a field model, rather than two particles attracting each other, the particles distort spacetime via their mass, and this distortion is what is perceived and measured as a “force”.
What is a force field and what does it do?
Force field (fiction), a barrier made up of energy, plasma or particles to protect a person, area or object from attacks or intrusions or as a means of containment or confinement.
What is force in physic?
In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate. A force has both magnitude and direction, making it a vector quantity.
What is the unit of the weight?
newtons
What is the basic unit of weight in the apothecary system?
The basic apothecaries’ system consists of the units pound, ounce and scruple from the classical Roman weight system, together with the originally Greek drachm and a new subdivision of the scruple into either 20 (“barley”) or 24 (“wheat”) grains (Latin: grana).
Which measuring parameter is used for liquids?
A measuring cup can be used to measure volumes of liquids. This cup measures volume in units of cups, fluid ounces, and millilitres. Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains.
What medications are measured in grains?
Though no longer recommended, in the U. S. grains are still used occasionally in medicine as part of the apothecaries’ system, especially in prescriptions for older medicines such as aspirin or phenobarbital. For example, the dosage of a standard 325 mg tablet of aspirin is sometimes given as 5 grains.
How much is a Troy grain?

Is flour a grain?
Whole grains contain the entire grain kernel ― the bran, germ, and endosperm. Examples of whole grains include whole-wheat flour, bulgur (cracked wheat), oatmeal, whole grain cornmeal, and brown rice.
Are peas considered a grain?
Pulses or grain legumes, members of the pea family, have a higher protein content than most other plant foods, at around 20%, while soybeans have as much as 35%. As is the case with all other whole plant foods, pulses also contain carbohydrate and fat. Common pulses include: common peas (garden peas)
Is corn starch a grain?
Corn starch, maize starch, or cornflour (British English) is the starch derived from corn (maize) grain. The starch is obtained from the endosperm of the kernel. Corn starch is a common food ingredient, often used to thicken sauces or soups, and to make corn syrup and other sugars.
Why is flour called flour?

How is semolina made into white flour?
As the wheat is fed into the mill, the rollers flake off the bran and germ while the starch (or endosperm) is cracked into coarse pieces in the process. Through sifting, these endosperm particles, the semolina, are separated from the bran. The semolina is then ground into flour.
