Some common forms of energy include the kinetic energy, it is of a moving object. The potential energy is stored by an object’s position in a force field. It can be gravitational, electric or magnetic. The elastic energy is stored by stretching solid objects. The chemical energy that is ...
Work is the product of the component of the force in the direction of the displacement and the magnitude of this displacement. Learn the factors on which work depends along with its formula, unit, and definition.
What is the difference between electric potential and electric potential energy? How are potential energy and kinetic energy similar? How are they different? Differentiate between stress and strain. Calculate the gradient nabla f of the function f (y) = k y, where k is a constant. ...
Work energy theorem. Potential energy of a spring. Mechanical energy and its conservation. Collision and its types. What is Work? Work happens when a force makes something move. For example, when a person climbs a mountain, work is being done because they are going against gravity to go up...
Explain about work and potential energy. How much work can a 9.0-hp motor do in 3.0 h ?. Name the physical quantity which is measured in (a) kWh (b) kW (c) Wh How much work can a 500 W electric mixe...
In summary, the conversation discusses the calculation of potential and potential difference between two points due to an electric charge, as well as the change in electric potential energy and the work done by the electric field. The solutions provided involve using the formula VA=kq/r and ...
Types of Work-Energy Theorem Various types of energy are there like potential energy, kinetic energy, thermal energy, electrical energy, chemical energy, and nuclear energy. Kinetic energy is basically the type of energy that an object or particle has as an outcome of its movement and when the...
The energy in motion is known as Kinetic Energy, whereas Potential Energy is the energy stored in an object and is measured by the amount of work done. Types of Energy Some other types of energy are given below: Mechanical energy Mechanical wave energy Chemical energy Electric energy Magnetic ...
Electrical Energy --The generation or use of electric power over a period of time expressed in kilowatt-hours (kWh), megawatt-hours (NM) or gigawatt-hours (GWh). Chemical Energy --Chemical energy is a form of potential energy related to the breaking and forming of chemical bonds. It is ...
Tags Mechanics Physics Potential In summary, the question posed is to calculate the work done in a steel wire that is 2.0m long and has a cross-sectional area of 0.010cm², with a modulus of elasticity of 200GPa, when it extends by 2.5mm when loaded. The formula for work done is ...
