These list of physic formula of class 11 chapter Work Energy Power is.
Work power and energy formulas. Kinetic Energy ½ m v 2 where m is the mass of the body and v is its velocity. Power is defined as the rate of doing work. η is the efficiency in percent.
Energy is a key principle in physics as it allows work to be done. In Physics power is associated with energy and has a precise meaning. Download the free Pdf sheet of list of physics formulas class 11 for IIT JEE NEET For chapter-Work Energy Power.
Work done on the particle is the sum of the individual work done by all the forces acting on the particles. Academic team of Entrancei prepared short notes and all important Physics formulas and bullet points of chapter Work Energy Power class-11 Physics. Ep12kx² k is the spring constant and x is the amount of compression or streching.
PEmgh m is the mass g is the gravitational acceleration and h is the distance. 6 Finish Newtons laws and circular motion Energy Work definition Examples of work Work and Kinetic Energy Conservative and non-conservative forces Work and Potential Energy Conservation of Energy. Power efficiency is defined as the ratio of the output power divided by the input power.
Unit of work is joule CGS unit is erg and its dimensions are ML2T2. It is represented by the letter W. Power is measured in joules per second Js r o watts W and is worked out using the formula.
Electric power is usually sold by electric companies as the kilowatt hour 36 MJ which is the product of power in kilowatts multiplied by running time in hours. In Todays NEET Physics lecture we will know practice physics formula based questions on the Work Power and Energy Physics Class 11 chapter 6 in a new series. In our study of mechanical work power and energy we learned that power is the time rate of doing work or consuming energy.
