Units of Strength
past Ron Kurtus
A strength is a button, pull, or dragging on an object that changes its velocity or direction. A unit of strength is an arbitrary measurement that we designate equally "1" (unit), so that all other measurements of force are multiples of that unit.
About often, strength is designated as a newton (N) in the metric or SI system of measurement. The newton has applications in diverse scientific measurements. In that location are other units, not used as often.
Questions you may have include:
- What is the definition of the newton?
- What are some applications of the newton?
- what are other units of force?
This lesson volition respond those questions. Useful tool: Units Conversion
Definition of newton
A newton is the force required to give a mass of 1 kilogram (1 kg) an acceleration of 1 meter per 2d per second (1 m/s2 ). Information technology is abbreviated as North.
This unit is in the metric or SI system and is used in scientific work more than other units of force.
1 N is equivalent to ane kg-yard/due southii .
Applications of the newton
The newton combined with other measurements is used in various applications.
Moment of force
The unit of measurement of torque or moment of force is the newton-meter (N-yard), where m is the moment arm.
Energy, piece of work and estrus
The newton-meter (N-g) is also the definition of the joule (J), which is a unit of energy. Information technology can be seen that the units of kinetic energy E = ½mv2 are in kilogram-meterii/secondsii and kg-m2/s2 = N-yard.
Power and radiant flux
Power is energy per second or Due north-chiliad/s, with the unit of watt. This is also the unit of measurement for radiant flux or power from electromagnetic radiation.
Pressure
The unit of pressure is the pascal (P), which is the force per unit of measurement area (Northward-m2 ).
Other units of force
At that place are other units of force, not as usually used as the newton.
Dyne
A dyne is the force required to give a mass of 1 gram (1 g) an acceleration of ane centimeter per 2nd per 2nd (1 cm/south2 ). 1 Northward = 100,000 dynes.
Yous might utilise the dyne, if working with minor objects.
Poundal and pound
A poundal is the force required to give a mass of 1 pound (one lb) an acceleration of ane foot per second per second (1 ft/south2 ). 1 poundal equals 0.1382 newtons.
A pound is the forcefulness applied on a mass of one pound (1 lb) by the acceleration due to gravity. It is a not-technical unit of force and is also chosen the weight.
These units of force are in the English system and are seldom used in scientific measurements.
Summary
A force acts on an object to change its velocity or direction. In virtually scientific work, strength is designated as a newton (Due north) in the metric or SI organisation of measurement. The newton has applications in various scientific measurements. There are other units, non used equally often.
