The change in Kinetic Energy is equal to the work. d Work can be done by you, as well as on you Are you the pusher or the pushee Work is a measure of expended energy Work makes you tired Machines make work easy (ramps, levers, etc.) However, in the science of dynamics, __ (44) __ and energy are important factors that can affect the motion of bodies. Ability to do work in a system. III. elastic energy energy stored when an object is stretched or compressed Power is Work per unit time. Force … Kinetic Energy, Work, Power, and Potential Energy - Kinetic Energy, Work, Power, and Potential Energy 8.01 W05D1 Work: Path Dependent Line Integral Work done by force along path from A to B In order to calculate the ... | PowerPoint PPT presentation | free to view New Concept: Kinetic Energy Table 7-1 Typical Values of Work Work is force times distance…but! Energy is always associated to strength and strong forces doing work. (iv) Energy in food indirectly comes from the Sun. The energy in a system may take on various forms such as thermal, light, electric, etc… but the energy may neither be created nor destroyed. Work = Force × Displacement W = F × S → Work is a scalar quantity. It is related to activities like the sport of weight lifting, waves crashing against the shores and many others. Force is the push or __ (45) __ of an object that tends to produce acceleration of the body's motion in the direction of the force. Therefore the sum of all energies in the system is a constant. View Chapter7_1-4_FA05.ppt from STEM 101 at Far Eastern University Manila. (v) Energy of wind can be used to generate electricity. There are many types of energy: kinetic energy energy of an object due to its speed. Energy is the measure of the ability of an object or a system to perform work. Improving Building Performance Achieving the maximum potential operational performance of the nation’s offices, schools, hospitals, and other commercial buildings offers significant energy savings. workforce credentials for four key energy-efficiency related jobs. → When a force of 1 Newton moves a body through a distance of 1 metre in its own direction, then the work done is 1 Joule. 1 Joule = 1 Newton × 1 metre 1 J = 1 Nm Force -- Work -- Energy The following activities target a middle school population although activities are approachable by more advanced elementary school students. Work = change in KE Units again… Work done by gravity Gravitational Potential Energy If gravity is the only force doing work… Work and Energy Physics 100 Chapt 5 Physicist’s definition of “work” Atlas holds up the Earth Garcon does work when he picks up the tray Why this definition? It also requires highly Complete the following sentence by inserting suitable words from the box: force, movement, energy, source, work, does, petrol (i) Energy is needed to perform _____. In Physics, energy is defined as the ability or capacity to do work. The activities are also ideal for high school students to review basic concepts. Mechanical Energy. Work, Energy, Power Chapter 7 in a nutshell Work is Force times Distance. Apply less force … Work, Energy, Power Chapter 7 in a nutshell Work is Force times Distance.
