What are the units for a 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. Named in honour of the English physicist James Prescott Joule, it equals 107 ergs, or approximately 0.7377 foot-pounds.
What is a kgm 2 S 2?
The amount of work is 1 kg*m^2/s^2 means that it is equivalent to 1 * N * m or 1 newton * meter. 1 newton is equivalent to the product of 1 kg and 1 m/s^2. Multiplying 1 N by 1 m gives 1 Nm of work or 1 joule of energy.
Why is energy kg/m2 s 2?
The amount of work is 1 kg*m^2/s^2 means that it is equivalent to 1 * N * m or 1 newton * meter. 1 newton is equivalent to the product of 1 kg and 1 m/s^2. Multiplying 1 N by 1 m gives 1 Nm of work or 1 joule of energy. Its equivalent symbols is 1 kg * 1 m/s^2 * 1 m.
What unit is KGM S 2?
newton
A newton is defined as 1 kg⋅m/s2, which is the force which gives a mass of 1 kilogram an acceleration of 1 metre per second, per second.

Is N Ma unit of energy?
The newton-metre (also newton metre or newton meter; symbol N⋅m or N m) is a unit of torque (also called moment) in the SI system. One newton-metre is equal to the torque resulting from a force of one newton applied perpendicularly to the end of a moment arm that is one metre long.
What is the unit of measurement for energy in joules?
Units defined exactly in terms of the joule include: 1 1 thermochemical calorie = 4.184 J 2 1 International Table calorie = 4.1868 J 3 1 W⋅h = 3600 J (or 3.6 kJ) 4 1 kW⋅h = 3.6 × 106 J (or 3.6 MJ) 5 1 W⋅s = 1 J 6 1 ton TNT = 4.184 GJ
What is the SI base unit for energy?
A joule is the SI base unit for energy. It is equal to [math]1 \\frac{kgm^2}{s^2}[/math].
What is the difference between a Joule and a kW/hr?
While the joule is the SI base unit for energy, when speaking in real-world terms, we often use the kilowatt-hour (kW/hr) instead. 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.
What is the formula for energy in physics?
Energy. Definition. In physics, we can define energy as the capacity to do work. Formula. For the potential energy the formula is. P.E. = mgh. Unit. The SI unit of energy is joules (J), which is named in honour of James Prescott Joule.
