What do you mean by 1 joule energy?

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. In electrical terms, the joule equals one watt-second—i.e., the energy released in one second by a current of one ampere through a resistance of one ohm.

How much work can 1 joule of energy do?

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 real life?

One joule is equal to the work done by a force of one newton to move an object one meter in the direction of the force. To use a real-life example, gravity exerts about 1 newton of force on the average apple. To raise an apple one meter in the air, you must use one joule of kinetic energy.

What is an example of 1 joule of energy?

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.

What are some examples of joules?

Everyday examples of the Joule. the energy required to lift a small apple one meter straight up. the energy released when that same apple falls one meter to the ground. the energy released as heat by a quiet person, every hundredth of a second.

What are kinetic energy and potential energy define 1 joule?

One joule is the amount of work done on an object when a force of 1 N displaces it by 1 m along the line of action of force. – KE = (1/2) m v^2. – 1 Joule = ( 1 kg ) ( 1 m/s)^2. – Joule is the kinetic energy possessed by a body whose mass is 1 kg and moving with a velocity of 1 m/s.

How is work related to energy define one joule of energy?

1 Joule is the amount of work done by a force of 1 Newton on an object that displaces it through a distance of 1 meter in the direction of the applied force. 1 J = 1 N x 1 m.

What is a joule example?

Everyday examples of the Joule. the energy required to lift a small apple one meter straight up. the energy released when that same apple falls one meter to the ground. the energy required to heat one gram of dry, cool air by 1 degree Celsius.

How much energy is 1kj?

It will not be uncommon to measure energies in thousands of joules, so the kilojoule (kJ) is a common unit of energy, with 1 kJ equal to 1,000 J. One area where the calorie is used is in nutrition. Energy contents of foods are often expressed in calories.
