What is the Joule formula?
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..
What unit is J m?
Thus, a kiloJoule (kJ) is 1000 Joules and a MegaJoule (MJ) is 1,000,000 Joules. A related unit is the Watt, which is a unit of power (energy per unit time).
How many joules does it take to kill you?
Henderson states, according to long established principles, an object which impacts a human is considered 20% chance of being lethal, with a head strike, if its kinetic energy is greater than 80 Joules. 90% chance of being lethal, with a head strike, it its kinetic energy is 150 Joules.
Is CM a derived unit?
Since volume is length cubed, its SI derived unit is m3. Related units are the cubic centimeter (cm3) and the cubic decimeter (dm3). … A liter is the volume occupied by one cubic decimeter. One liter of volume is equal to 1000 mililiters (mL), and one mililiter of volume is equal to one cubic centimeter.
Is time a derived unit?
Fundamental units of measurements are kilograms, meters, and seconds—in regards to mass length, and time. … These derived units can be expressed in terms of fundamental units, such as acceleration, area, energy, force, power, velocity and volume.
Is Joule equal to Newton meters?
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). …
What is joules meter?
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 do you mean by 1 Joule?
Joule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre. … In electrical terms, the joule equals one watt-second—i.e., the energy released in one second by a current of one ampere through a resistance of one ohm.
How many volts is 500 joules?

How many joules are in a Watt?
1 jouleThe most common unit is the watt (W), defined as 1 joule (J) of energy per second. A 40 W light bulb, then, uses 40 J of electrical energy every second to stay lit.
How many volts are in a Joule?
1 voltWhere: voltage is in Volts, J is the work or energy in Joules and C is the charge in Coulombs. Thus if J = 1 joule, C = 1 coulomb, then V will equal 1 volt.
How do you convert joules to KG?
Work = Mass * Gravity * Height and is measured in Joules. Imagine you find a 2 -Kg book on the floor and lift it 0.75 meters and put it on a table. Remember, that “force” is simply a push or a pull. If you lift 100 kg of mass 1-meter, you will have done 980 Joules of work.
What is equal to Newton meter?
The newton meter is a measurement of torque. One newton meter is equal to approximately 0.738 pound-feet. It’s easy to confuse the newton meter with newton times a meter, which is a joule and a unit of energy.
How do you convert joules to meters?

What does 200 joules mean?
Energy absorption/dissipation – This rating, given in joules, tells you how much energy the surge protector can absorb before it fails. A higher number indicates greater protection. Look for a protector that is at least rated at 200 to 400 joules. For better protection, look for a rating of 600 joules or more.
How many joules is 60 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 is work formula?
Work is done when a force that is applied to an object moves that object. The work is calculated by multiplying the force by the amount of movement of an object (W = F * d).
Is J kg the same as M s?
How many joules/second in 1 kg-m/s? The answer is 9.80665. We assume you are converting between joule/second and kilogram-force meter/second. You can view more details on each measurement unit: joules/second or kg-m/s The SI derived unit for power is the watt.
