Which chapter is work energy and power Class 11?
Chapter 6
Class 11 Physics Revision Notes for Chapter 6 – Work, Energy and Power.
What is work energy principle Class 11?
The work-energy principle states that an increase in the kinetic energy of a rigid body is caused by an equal amount of positive work done on the body by the resultant force acting on that body. Conversely, a decrease in kinetic energy is caused by an equal amount of negative work done by the resultant force.
What is class 11 physics work?
In Physics, work is defined as the product of force and displacement. If an object is acted upon by a force, work done is nothing but the product of the magnitude of this force and the displacement of the object caused by the force.
What is work power and energy?
Work, Energy and Power are fundamental concepts of Physics. Work is said to be done when a force (push or pull) applied to an object causes a displacement of the object. We define the capacity to do the work as energy. Power is the work done per unit of time.
What is Torque in physics class 11?
Torque is the measure of the force that can cause an object to rotate about an axis. Force is what causes an object to accelerate in linear kinematics. Similarly, torque is what causes an angular acceleration. Hence, torque can be defined as the rotational equivalent of linear force.
What is work and its SI unit?
Work is a mechanical manifestation of energy. The standard unit of work is the joule (J), equivalent to a newton – meter (N · m). This reduces to one kilogram-meter squared per second squared (kg · m 2 /s 2 or kg · m 2 · s -2 ) in base International System of Units (SI) units.
What is work-energy theorem formula?
The net work done on a particle equals the change in the particle’s kinetic energy: W net = K B − K A . W net = K B − K A .
What is the SI unit of power?
The S.I. unit of power is watt (W). When a body does work at the rate of 1 joule per second, its power is 1 watt.
What is the formula for work and power?
Work and Power Difference in Tabular Form
| Criteria | Work |
|---|---|
| Formula | Total Work Done (W) = Power (P) x Time (t) or Work = Displacement x Force |
| Measurement Unit (SI unit) | The standard unit of work is the Joule denoted as (J). Furthermore, you can measure work in electron volt (eV), kWh, GWh, and MWh |
What is the SI unit of work?
The SI unit of work is the joule (J). It is defined as the work done by a force of one newton through a distance of one metre.
What is work Class 11 notes physics?
Work, Energy and Power Class 11 Notes Physics Chapter 6. • Work is said to be done when a force applied on the body displaces the body through a certain distance in the direction of applied force. It is measured by the product of the force and the distance moved in the direction of the force, i.e., W = F-S.
What is work power and energy in physics?
Work, energy and power are the most used terms in Physics. They are probably the first thing you learn in your Physics class. Work and energy can be considered as two sides of the same coin. In this article, we will learn all about the concept of work, power and energy. Work done is generally referred in relation to the force applied
