Questions to Think About. In which direction should you apply a force in order to generate the most power? Why would a pole vaulter need to switch to a stiffer pole in order to vault higher? Mechanical Work. We rst introduce the ideas of work and power. The notion of work can be viewed as the bridge between Newtons second law, and energy (which we have yet to dene and discuss). Gallery of Mechanics Work Energy And Power Pdf. mechanics work energy and power pdf. springs know when mechanical energy is conserved. 6.0 Introduction. When you walk, run or cycle up a hill or go upstairs you know that it takes more effort than on the level.All these activities involve the ideas of work, energy and power developed in this chapter. Work, Energy and Power. Mechanical Energy: (units in joules, J, equal to 1 newton metre, similar to units of moments of force).

A positive value means the force did work on the body increasing its mechanical energy. AP Physics C Mechanics. Unit 4 - Work, Power, Conservation of Energy 4. Space Probes, Work, Kinematics Suppose a mechanical probe of mass 5 x 104 kg and initial velocity of 1.1 x 104 m/s is out in space. 02 Gravitational Potential Energy 7:50 Non-isolated systems work and energy 8:29 Isolated systems work and energy 9:02 Conservative vs. Nonconservative forces 10:10 Conservation of Mechanical Energy 10:45 Power 12:09 Every derivative can be an integral 13 WORK, POWER AND ENERGY All of us use words like work, power and energy.3 Energy the capacity to do work (scalar) Types of energy: mechanical, chemical, heat, sound, light, etc We are most interested in mechanical energy. Work of a constant force. W F Dx cosa. (Force is parallel to displacement).Elastic potential energy Mechanical (total) energy Mechanical energy conservation. Inelastic collision Elastic collision. Power Unit conversions. All of us use words like work, power and energy.

The source of part of the electric energy we consume comes from the energy stored in the reservoirs A powerful hoist needs energy (fuel) to keep on working. 3th Edition.

In this section of the Transport unit, we will look at the energy changes that take place when a force acts upon an object. Energy cant be created or destroyed, it can only be changed from one type into another type. Work, power and energy. Collisions.

Work If a force acts on a body and causes it to move, then the force is doing work. W Fs W work done (J) F force applied (N) s distance moved in the direction of the force (m). Chapter 7 Work and Energy. In principle, all problems in classical mechanics can be solved by using Netwons laws. In practice, we often have little information on the forces involved in a given situation. The terms work, energy and power are frequently used in everyday language. A farmer ploughing the field, a construction worker carrying bricks, a student studying for a competitive examination, an artist painting a beautiful landscape, all are said to be working.

We need some new maths: The scalar product.or: mechanical energy E is conserved Equivalent to Newton 2, but useful for many mechanics problems where integration is difficult. Energy is needed to do useful work. Energy can move things, heat things up, cool them down, join things, break things, cut things, make noise, make light, and power our electronics, etc. Energy can be changed from one form to another.
