WebIt 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). It is related to the watt (a unit of power): one watt equals one joule per second. WebOct 13, 2024 · Definition of Joule. Joule is defined as the SI unit for measuring the amount of work done or energy. However, one joule can be stated as the net amount of energy that is exerted at the time of application of one-Newton force over a displacement that occurs through 1 meter (Electronics-tutorials.ws, 2024).
Joule - Wikipedia
WebEnergy is measured in joules (J) or kilojoules (kJ). An older unit for measuring food energy is the kilocalorie, often just called calories. One calorie is 4.2 J. WebJul 22, 2024 · Using the relationship 1 Cal = 1,000 cal, we can answer the first question with a one-step conversion: 70.0 C a l × 1, 000 c a l 1 C a l = 70, 000 c a l. Then we convert calories into joules. 70, 000 c a l × 4.184 J 1 c a l = 293, 000 J. and then kilojoules. 293, 000 J × 1 k J 1, 000 J = 293 k J.

Examples of Energy of 1 Joule - Nuclear Power
WebAug 14, 2016 · One volt is defined as the voltage at which one ampere current has the power of one watt. Equivalently (because of the multiplication by t explained in the first paragraph), one volt is defined as the voltage at which one coulomb of charge gains the energy of one joule. So. 1 V = 1 J 1 C = 1 J / s 1 C / s = 1 W 1 A. WebExamples of Energy of 1 Joule. One joule in everyday life and science corresponds to approximately:. The kinetic energy of an object with mass 1 kg moving at √2 ≈ 1.4 m/s.; The kinetic energy of a 50 kg object (e.g.,, human) moving very slowly – approximately 0.72 km/h.; The energy required to lift a medium-size apple (100 g) 1 meter vertically from the … WebDec 13, 2024 · Explanation: Joule is a unit of energy, kinetic, potential, electric etc. When a force of 1N (Newton),moves a body of mass 1kg, it will produce an acceleration of 1m/s² in the body of mass 1 kg. In case under the action of the force of 1N, the body moves a distance of 1m, in the direction of the force, the work done by force on the body is 1Joule. shoprite george contact details
