2019-12-17Power is the work done in a unit of time. In other words, power is a measure of how quickly work can be done. The unit of power is the Watt 1 Joule 1 second. One common unit of energy is the kilowatt-hour kWh. If we are using one kW of power, a kWh of energy will last one hour. Calculating Work, Energy and Power.

Gravitational Energy - Stored energy in raised objects. Chemical Energy - Stored energy in fuel, foods and batteries. Sound Energy - released by vibrating objects. Electrical Energy - found in moving or static electric charges. Elastic Energy- Stored energy in stretched or squashed objects. Nuclear Energy - Stored in the nuclei of atoms.
2008-8-26Work, Energy, Power Chapter 7 in a nutshell Work is Force times Distance. The change in Kinetic Energy is equal to the work. Power is Work per unit time. New Concept Kinetic Energy Table 7-1 Typical Values of Work Work is force times distancebut Force in direction of motion is what matters
2020-5-9Work-Energy Theorem. Work done by a force in displacing a body is equal to change in its kinetic energy. where, K i initial kinetic energy. and K f final kinetic energy. Regarding the work-energy theorem it is worth noting that i If W net is positive, then K f K i positive, i.e., K f K i or kinetic energy will increase and vice-versa.
2020-5-22Work done by Constant Force In fact, work is the scalar product dot product of the force vector and the displacement vector. Thus , W FS cos . Where F and S are the magnitude of force and displacement vectors and is the angle between them. For cos positive, W positive. For 2 , W Zero. For 2 32, work is ...

2020-5-24Work, energy and power Lesson for 16-19 For this reason you may want to state the basic physics with clarity and brevity at the beginning of the topic to allow the students as much time as possible performing the experiment.
Work, energy, and power are three important concepts in the field of Physics. The work done by all the forces is equal to the change that takes place in kinetic energy. Work, for instance, relates to the total amount of energy that gets transferred to or from a system by a force.
