What is 1J equivalent to?
What is 1J equivalent to?
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 is a joule in base units?
The SI unit of energy is the joule (J). The joule has base units of kg·m²/s² = N·m. A joule is defined as the work done or energy required to exert a force of one newton for a distance of one metre.
What is a joule J of energy?
1 Joule (J) is the MKS unit of energy, equal to the force of one Newton acting through one meter. 1 Watt is the power of a Joule of energy per second. Power = Current x Voltage (P = I V) 1 Watt is the power from a current of 1 Ampere flowing through 1 Volt.
What is 1 joule of work how is it related with ERG?
Joule is the SI unit of energy while erg is the cgs unit of energy. Therefore, 1 Joule is equal to 107 erg.
What is J in thermodynamics?
The joule (/ˈdʒuːl/ JOOL, also /ˈdʒaʊl/ JOWL; symbol: J) is a derived unit of energy in the International System of Units. It is equal to the amount of work done when a force of 1 newton displaces a mass through a distance of 1 metre in the direction of the force applied.
Is joule a SI unit?
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.
What is the SI unit of energy?
The SI unit of energy is same as that of work, which is joule (J).
What is joules formula?
Multiply the mass of the object by its specific heat capacity and by the amount of temperature change. This formula is written H = mcΔT, where ΔT means “change in temperature.” For this example, this would be 500g x 4.19 x 20, or 41,900 joules.
What does J stand for in chemistry?
J (J): (1) The joule. An International System of Units energy unit equal to an applied force of one newton through a distance of one meter, or the energy equivalent to passing an electric current of one ampere through a resistance of one ohm for one second.
What is the relation between dyne and erg?
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 is erg in energy?
erg, unit of energy or work in the centimetre-gram-second system of physical units used in physics; to lift a pound weight one foot requires 1.356 × 107 ergs. It equals the work done by a force of one dyne acting through a distance of one centimetre and is equal to 10-7 joule, the standard unit of work or energy.
