This broad question may have a number of answers. Which force is being measured? Magnetic? Electrostatic? Gravitational? Different forces are measured in different ways. Sometimes some clever experiments must be concocted to actually perform a measurement. As there are many answers, let's just look at a couple of instances. The phenomenon of piezoelectric effect is a simple concept, though it is a bit subtle in it's underlying nature. What this is all about is based on the fact that by compressing a crystal of something that exhibits piezoelectric properties, we can observe a tiny generated voltage (electromotive force or EMF). By setting up a tiny crystal of, say, lead zirconate titanate, a commonly selected material, we can observe the force created on the crystal by the weight (mass in a gravimetric field) of a small object. The mass of the tiny gem presses down on the crystal and a tiny voltage is created. We measure this voltage and convert it to a weight, and the weight of our gemstone is then discovered. We can weigh tiny gemstones with great accuracy using piezoelectric scales. The piezoelectric principle can be used to measure small forces in the same way it is used in this application. Electricity was a mystery for a long time. Then it was discovered that it "flowed" and, therefore, must be "liquid-like" tiny particles. The electron was discovered. And then we needed to know the charge on the electron. The electrostatic force an electron exerts on other electrons and between themselves and protons is a function of (among some other things) the field strength of the electron. How much force does that field generate? Robert Millikan, with considerable help from Harvey Fletcher, electrically charged tiny droplets of oil and let them fall through air in the presence of a vertically oriented electrostatic field. By varying the field voltage, they could actually suspend at drop in air. (The electrostatic force holding the drop offset the effects of gravity - the drop stood still in air.) By making computations based on the size of the drop (including some factors for the effect of the air) the number of carges suspending it could be calculated. Repeating the experiment over many trials allowed them to find a "fundamental unit charge" that represented the charge on the electron. It was good enough work to win a Nobel Prize in Physics for Millikan. A link is provided to the oil-drop experiment as posted by our friends at Wikipedia, where knowledge is free.
what do you use to measure forces
to measure forces what do you use?
we measure force in newtons (N)
There is no instrument in world which measure how small an object is but instruments measure how large an object is .
There are some forces in nature whose ranges are very small. So small that they can only be felt at the microscopic level. One such forces is the nuclear forces. these forces are called nuclear forces because they are only dominant at the nuclear level.
It measures forces in Newtons.
It is used to measure forces.
Weight is a measure of the mutual forces of attraction between the earth and any object.The forces are due to a property of space called "gravity".
You can either (1) measure what force is required to balance the other two forces, or (2) measure the object's acceleration.
You can use cups to measure a small can of juice.
A spring balance used to measure forces. Most commonly used to measure weight forces. The scale hung above the fruits at the super market is an example.
Small quantities are measured in millimeters. Millimeters is used to measure small quantities.
Guerrilla forces were irregular armed forces that fought with harassment and sabotage. They had limited actions and were small scaled.
A force meter is a device used to measure forces of the universe. It can measure friction, tension, and gravity.
A bathroom scale can do that.
A bathroom scale can.
