What is GPE GCSE?
Ep = m × g × h Ep = gravitational potential energy, in Joules (J) m = mass, in kilograms (kg) g = gravitational field strength in Newtons per kilogram (N/kg)
What are the units of power?
WattPower / SI unit Units. The dimension of power is energy divided by time. In the International System of Units (SI), the unit of power is the watt (W), which is equal to one joule per second. Other common and traditional measures are horsepower (hp), comparing to the power of a horse; one mechanical horsepower equals about 745.7 watts.
How do you calculate energy in joules?
If you multiply the number of watts by the number of seconds, you'll end up with joules. To find out how much energy a 60W light bulb consumes in 120 seconds, simply multiply (60 watts) x (120 seconds) = 7200 Joules.

Is joules a unit of power?
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.
Is joule unit of energy?
1 Units. The SI unit for energy is the joule (J): 1 J=1 newton metre (N m). Another unit is the calorie (cal), which is defined as the heat required to raise the temperature of 1 g of pure water by 1°C at 1 atm pressure.
What are joules of energy?
One joule is defined as the amount of energy exerted when a force of one newton is applied over a displacement of one meter. One joule is the equivalent of one watt of power radiated or dissipated for one second. In some applications, the British thermal unit (Btu) is used to express energy.
What units are joules in?
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.
Is power a watt or joule?
Watts are the SI unit of power. Kilowatts are equivalent to 1,000 Watts and are the most frequently used unit of electrical power. Power in general is defined as energy over time. Watts are defined as 1 Watt = 1 Joule per second (1W = 1 J/s) which means that 1 kW = 1000 J/s.
What does unit J represent?
The joule (symbol J) is the SI unit of energy—a measure of the capacity to do work or generate heat. One joule equals the work done (or energy expended) by a force of one newton (N) acting over a distance of one meter (m).
What is the energy unit?
Joule (J). This is the basic energy unit of the metric system, or in a later more comprehensive formulation, the International System of Units (SI). It is ultimately defined in terms of the meter, kilogram, and second.
Is joules in kg or g?
