What is K in physics spring?
k is the spring constant, in Newtons per meter (N/m), and x is the displacement of the spring from its equilibrium position.
The spring constant, k, is representative of how stiff the spring is.
Stiffer (more difficult to stretch) springs have higher spring constants..
What is the value of 1 J?
Answer. 1 joule➙ The amount of energy exerted when a force if 1 N is applied over a displacement of 1 m. ❖ 1 joule is equal to 1 wattof power radiated for one second is the unit of energy. ❖ The millijoules unit number 1,000.00 mJ converts to 1 J, one joule.
What is a joule equal to in terms of kg M and S?
Then, in terms of SI base units a joule is equal to a kilogram times meter squared divided by a second squared (kg×m2s2) ( kg × m 2 s 2 ) . Another common unit of energy that is often used is the calorie (cal), which is equivalent to 4.184 J.
What units make up a joule?
One joule equals the work done (or energy expended) by a force of one newton (N) acting over a distance of one meter (m). One newton equals a force that produces an acceleration of one meter per second (s) per second on a one kilogram (kg) mass. Therefore, one joule equals one newton•meter.
What does V in physics stand for?
electric potential difference voltvoltage. also called electric potential difference. volt (V) volume. cubic meter (m3)
What is kJ equal to?
one thousandThe kilojoule (kJ) is equal to one thousand (103) joules. Nutritional food labels in most countries express energy in kilojoules (kJ). One square metre of the Earth receives about 1.4 kilojoules of solar radiation every second in full daylight.
What is meant by 1 Joule of work?
One joule of work is done on an object when a force of one newton is applied over a distance of one meter. The joule is named after James Prescott Joule who lived from 1818 until 1889.
What is the CGS unit of work?
An erg is the amount of work done by a force of one dyne exerted for a distance of one centimetre. In the CGS base units, it is equal to one gram centimetre-squared per second-squared (g⋅cm2/s2).

What unit is kg * m s?
The newton-second (also newton second; symbol: N⋅s or N s) is the derived SI unit of impulse. It is dimensionally equivalent to the momentum unit kilogram-metre per second (kg⋅m/s).
Is J kg the same as M s?
As any physics student can tell you, a Joule is one kilogram – meter squared per second squared. That is, a Newton times meters. This means you are making a force of 1 Newton along one meter of length. A force of 1 Newton changes the speed of a mass of 1 kilogram in one meter per second each second.
What is the formula of one joule?
In words: Work is equal to the force that is exerted times the distance over which it is exerted. In equation form: work (joules) = force (newtons) x distance (meters), where a joule is the unit of work, as defined in the following paragraph.
How much is 1 Joule in Watts?
Watts are defined as 1 Watt = 1 Joule per second (1W = 1 J/s) which means that 1 kW = 1000 J/s. A Watt is the amount of energy (in Joules) that an electrical device (such as a light) is burning per second that it’s running. So a 60W bulb is burning 60 Joules of energy every second you have it turned on.

What do SI units stand for?
International System of UnitsThe International System of Units (SI), commonly known as the metric system, is the international standard for measurement.
What do you mean by 1 Joule?
noun. the derived SI unit of work or energy; the work done when the point of application of a force of 1 newton is displaced through a distance of 1 metre in the direction of the force. 1 joule is equivalent to 1 watt-second, 10 7 ergs, 0.2390 calories, or 0.738 foot-poundSymbol: J.

What is the definition of Joule in terms of SI units?
The joule ( jawl, jool; symbol: J) is a derived unit of energy in the International System of Units. It is equal to the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of the force’s motion through a distance of one metre (1 newton metre or N⋅m).
