What is the kinetic energy of an electron with a velocity of 3551 m/s ? (Answer in units of J) What is the difference between potential and kinetic energy? What are the units for momentum? What is the mass of an object with kinetic energy of 1000 Joules and velocity of 5 meters per...
It is also equal to one watt of power emitted or dissipated for one second, or watt second (Ws). In various applications, British thermal units (BTU) are used to express the unit for energy. One BTU is equal to approximately 1,055 joules. One joule is equal to: 1× 107 erg (...
The International System of Units is a global standard for expressing the magnitudes or quantities of important natural phenomena. Also referred to as the metric system, the System of Units is commonly abbreviated as SI, which comes from the original French name, Système international d'unités. ...
Heat is the energy transferred in a process due to a difference in temperature. Heat is usually expressed using specific units like Joules or calories. These units of measurement can be interconverted using specific conversion factors.Answer and Explanation: ...

Electric potential energy is measured in units of joules (J). Electric Potential Electric potential builds upon electric potential energy to help define how much energy is stored in electric fields. It's another concept which helps us model the behavior of electric fields. Electric potential is ...
Eis the energy in joules; mis the mass in kilograms;andcis the speed of light, which is approximately 2.99792 x 108meters per second in a vacuum. The transformation of mass into energy also occurs during nuclear fission, in which the nucleus of a heavy element -- e.g., uranium -- spli...
Voltage surge and spike protection: A UPS protects electronic equipment at times when the voltage on the line is greater than it should be. Voltage sags: Some UPS units can normalize under-voltages and over-voltages, which ensures optimal operation and preserves battery life for more serious powe...
When it falls, it has kinetic energy, because it is moving. Discussion Questions Energy is the ability to do work. Work means moving an object by some distance. For instance, moving your hand requires energy. Energy can be classified as either potential (stored) energy or kinetic energy,...
The erg is a unit of energy equal to 10−7 joules (100 nJ). It originated in the centimetre–gram–second (CGS) system of units. Joule The International System unit of electrical, mechanical, and thermal energy, equal to the work done when a force of one newton acts through a distanc...
