What is a joule in simple terms?
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 joule and example?
One joule is equal to the work it takes to make a watt of power for a second, or to move a body one meter with a one-Newton force. In physics, it’s common to talk about joules of energy — one example used to illustrate a joule is lifting an apple, which weighs about one Newton.
How many joules are in a apple?
4.5 joules
The potential energy of an apple is 4.5 joules.
How are watts and joules related?
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 joules for kids?
A joule ( or sometimes) is a unit in the SI system. It measures energy; usually in scientific or electrical appliances . It is named after James Prescott Joule. A joule refers to the amount of energy transferred to an object when a force of 1 newton is applied on it over a distance of 1 metre (1J = 1N × 1m).
How many Joules are in a lightning bolt?
one billion
With an average bolt of lightning striking from cloud to ground containing roughly one billion (1,000,000,000) joules of energy, that is a lot of power in every lightning bolt!
How many Joules is a punch?
A proffesional boxer’s punch can range between 700 and 1000 joules.
How many joules does it take to power a house?
A 400 megawatt (400,000 kilowatt) power station is said to be “enough to power 400,000 homes”. That’s because, nationwide, the average home consumer buys about 9800 kilowatt-hours ( 36 gigajoules (GJ).
How many KJ does it take to power a house?
There are 3,600 kilojoules in a kilowatt-hour, which is why we use this value in the formula above. Kilowatt-hours and kilojoules are both units used to measure energy. Keep reading to learn more about each unit of measure.
Are Joules and Boden the same company?
Back off, Boden: the go-to label for the rural set — Prince George included — is Joules. Here’s the power of the pink welly. Nope, it’s the “country lifestyle” brand Joules.
What are Joules on a surge protector?
The joule rating refers to how much energy your surge protector can absorb. In this case, a higher rating equals better protection. A surge protector with a rating or 1,000 joules will last longer than a surge protector with a rating of 500 joules.
What can you do with 1 billion joules of energy?
An average bolt of lightning, striking from cloud to ground, contains roughly one billion (1,000,000,000) joules of energy. This is no small amount, enough to power a 60-watt lightbulb for six months plus a forgotten open door refrigerator for a day.
What is the formula to calculate joules?
Formula for calculating the Volts (V) to Joules (J) E (J) = V (V) x Q (C), which means that the energy in Joules is calculated by multiplying the voltage in volts by the electrical charge in coulombs.
What units are equivalent to a Joule?
Watt second. A watt second (also watt-second, symbol W s or W·s) is a derived unit of energy equivalent to the joule. The watt-second is the energy equivalent to the power of one watt sustained for one second.
What is used to measure joules?
A unit used to measure energy or work. One joule is equal to the work done when a force of one newton acts over a distance of one meter.
What does the name joules mean?
