Question: What Is The Value Of 1 J?

How much is 1 Joule in Watts?

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..

Which Joule is 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. Named in honour of the English physicist James Prescott Joule, it equals 107 ergs, or approximately 0.7377 foot-pounds.

How much force is in a Joule?

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 value of 1 Joule in CGS unit?

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 the relationship between joule and erg?Related Questions & AnswersMatter In Any Form Is Made Up Of Fill In The BlankWhat Is Esterification4 more rows•Aug 12, 2020

What is the formula for 1 Joule?

Joule is the SI unit of work done. Therefore, the dimensional formula of Joule is the same as that of the work done. On substituting equation (2) and (3) in equation (1) we get, Work (Joule)= F × D = [M1 L1 T-2] × [L1] = [M1 L2 T-2].

Can you convert joules to Watts?

How to convert energy in joules (J) to electric power in watts (W). You can calculate watts from joules and seconds, but you can’t convert joules to watts, since joule and watt units represent different quantities.

What is PE and Ke?

Summary. Energy is the ability to do work. Potential Energy (PE) is stored energy due to position or state. PE due to gravity = m g h. Kinetic Energy (KE) is energy of motion.

What is the magnitude of 1 kWh in joules?

3600000 joules1 Kilowatt hour (kWh) is equal to 3600000 joules (J).

What is Ke formula?

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

How many joules is a lightning strike?

1 million joulesThe average lightning strike contains about 1 million joules, enough energy to fry the founding father in his boots. “The typical house in the U.S. has 100 amp service or about 28 horsepower,” says Kirtley.

How do you calculate ke?

In classical mechanics, kinetic energy (KE) is equal to half of an object’s mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.

How do you calculate work?

Work can be calculated with the equation: Work = Force × Distance. The SI unit for work is the joule (J), or Newton • meter (N • m). One joule equals the amount of work that is done when 1 N of force moves an object over a distance of 1 m.

What do you mean by 1 Joule?

One joule is equal to the energy used to accelerate a body with a mass of one kilogram using one newton of force over a distance of one meter. One joule is also equivalent to one watt-second.

What is difference between Joule and Watt?

A watt equals a joule per second. If a smart phone uses five joules of energy every second, then the power of the phone is five joules per second, or five watts. The animation above demonstrates the difference between energy and power.
