| What is the unit of measurement for force?|
|Question Date: 2020-04-23|
The unit of measurement for force depends on what unit-system you use. Let's consider the 2 most popular unit-systems: the metric system and the imperial system. In the metric system, the unit of measurement for force is the "Newton." A Newton is the force required to make 1 kilogram object accelerate 1 meter-per second-per second (1m/s2). The symbol for the "Newton" is "N." The Newton was named after Sir Isaac Newton, the British scientist who formulated the 3 Laws of Motion in 1687.
In the imperial system, the unit for force is the "pound." This is actually the unit we use for weight in the United States. Your weight is actually the amount of force your body experiences as the Earth's gravity pulls you toward its center. The symbol for pound is "lb." Does it sound weird to you? Well, the symbol, "lb" actually came from the constellation, "Libra," which is Latin for weighing scales.
Hi Mina. The unit of measurement for force is the Newton, abbreviated N. It was named after Sir Issac Newton, in honor of his work on motion and forces. For example, an apple exerts one Newton of force on Earth. Next time you hold an apple you will feel 1N of force!
Force is most often measured in "Newtons", abbreviated N. As you probably guessed, it is named after Isaac Newton.
1 Newton is the force required to take a 1 kilogram (kg) mass and give it an acceleration of 1 meter/second-squared.
This means that if you have a 1 kg object at rest, and you push on it continuously with a force of 1 N (assuming there is no friction, or anything complicated), after 1 second, the object will be moving at a speed of 1 meter per second.
Maybe you are really strong, and you can apply a force that accelerates a 100 kg mass at 1 meter per second squared- in that case, the magnitude of the force would be 100 N.
If you are converting units, 1 Newton is equal to 1 kg*m/second-squared.
This is the “Newton”, abbreviated N. The derived quantities are kg m/s2, which follows from one definition of Force, which is (mass) x (acceleration).
The standard metric unit of force is the Newton. The standard imperial unit of force is the pound.
There is more than 1 unit of measurement for force, just like there are many units of measurement for distance -In the English system we measure length in inches, feet, yards, & miles.In the Metric system, we measure length in meters and other units such as centimeters and kilometers.
In the English system, pounds are a measure of force, on Earth, in Earth's gravity. Force = mass x acceleration.
If something's just sitting on Earth, its acceleration is the acceleration of gravity. It's confusing because we use pounds to describe our mass, too.
In the metric system, the main unit of force is the Newton. For example, an object with a mass of one kilogram has a weight of about 9.8 newtons on the surface of the Earth, and about one-sixth as much on the Moon.
The international standard (International System of Units, abbreviated as SI) unit of force is the Newton (symbol N) .
Fundamentally, force is an interaction which causes a change to the motion of a body. In other words, a force causes an object of some amount of mass to experience a change in velocity of some amount per unit of time. This is embodied in Newton's 2nd law of motion,
force F = m * a
(m = mass, and a = acceleration = change in velocity per unit of time).
As can be seen from this formula, force is "built from" more fundamental measures. Such quantities are called derived quantities, and the units of such quantities are derived units.
Force, as can be seen by the above formula, is a derived quantity, and the unit Newton is derived by multiplying the units of mass by acceleration. Written in SI units, mass has units of kg and acceleration has units of m/s2 (meters per second per second). This means that the newton unit can be converted to other units using 1 N = 1 kg * m/s2. Notice also that acceleration is a derived quantity, combining the base SI units of meters and seconds.
Other units of force related to SI units are the dyne (1 N = 100,000 dyne) , and the kilogram-force or kilopond (1 N ≈ 0.102 kp). In the US Customary System (i.e., using pounds and feet), the units of force are pound-force (1 N = 0.22481 lbf) and poundal (1 N = 7.233 pdl). These are also derived units found by multiplying together different units for mass and acceleration measures.
