What is a joule equal to in units?
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 from a current of 1 Ampere flowing through 1 Volt. 1 kilowatt is a thousand Watts.
What unit is kg/m2 s2?
The joule (J) is the SI unit of energy and equals (kg×m2s2) ( kg × m 2 s 2 ) .
What is a joule equal 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.
Which unit is equivalent to a joule second?
In SI base units the joule-second becomes kilogram-meter squared-per second or kg⋅m 2 ⋅s − 1 . Dimensional Analysis of the joule-second yields M L 2 T − 1 .
What is the formula for 1 Joule?
Work (Joule)= F × D = [M 1 L 1 T – 2 ] × [L 1 ] = [M 1 L 2 T – 2 ]. Therefore, Joule is dimensionally represented as [M 1 L 2 T – 2 ] .
Is 1 Joule a lot?
In physical terms, lifting an apple one meter takes 1 joule of energy . ... This is due to the fact that a joule is an extremely small amount of energy. To put how small a joule is into perspective, a liter of gasoline has 31,536,000 joules of energy in it. A kilowatt-hour is equal to 3,600,000 joules.
Is kg/m s 2 a derived unit?
The SI has special names for 22 of these derived units (for example, hertz, the SI unit of measurement of frequency), but the rest merely reflect their derivation: for example, the square metre (m 2 ), the SI derived unit of area; and the kilogram per cubic metre (kg/m 3 or kg⋅m − 3 ), the SI derived unit of density.
What is kg/m s2 M stands for?
The kilogram-meter per second (kg · m/s or kg · m · s – 1 ) is the standard unit of momentum . Reduced to base units in the International System of Units ( SI ), a kilogram-meter per second is the equivalent of a newton-second (N · s), which is the SI unit of impulse . ... This is equal to 16 minutes and 40 seconds.
What type of unit is kg m3?
The kilogram per cubic metre (symbol: kg·m − 3 , or kg/m 3 ) is an SI derived unit of density , defined by mass in kilograms divided by volume in cubic metres.
How much force is a joule?
1 joule of work = 1 N of force x 1 m of distance
In the English system of units, where force is measured in pounds, work is measured in a unit called the foot-pound (usually abbreviated ft-lb).
How much is a joule in volts?
| How many Joules are: Equivalence in Volts: | 1 Joule Equivalent to 0.1 Volts | 2 Joule 0.2 Volts | 3 Joule 0.3 Volts | 4 Joule 0.4 Volts |

Is joule a derived unit?
The joule (/dʒaʊl, dʒuːl/ jowl, jool; symbol: J) is a derived unit of energy in the International System of Units.
Which of the following is smallest unit?
Answer: Option C – Fermi is the smallest unit of measurement.
Is J an SI unit?
The SI unit for energy is the joule (J): 1 J=1 newton metre (N m).
What is joule coulomb?
Joule is a unit for work done and coulomb is the unit for the charge. The potential is defined as the ratio of the work done to the charge and the unit of the potential difference is volt. Hence, one joule per coulomb is equal to the unit of the potential difference. Therefore it will be equal to one Volt .
