Define energy and briefly discuss each of the following forms of energy: Potential energy Kinetic energy Heat energy Electrical energy Chemical energy 2. Formulate the law of conservation of energy 3. Differentiate between Radiation, Convectionand Conduction 4. Indicate the transformation of energy between the above-mentioned forms of energy by means of the law of conservation of energy (no fom1ulae). 5. Define the terms 'work' and 'power'. 6. Plot force/distance graphs according to scale of the work done to lift a load by means of a constant force. 7. Determine from the graph the work done, and then calculate the power required. 8. Calculate the work done and the power required on a horizontal and vertical plane by application and manipulation of the formulae: W=Fxs ;P=w/t; P= Fxv 9. Restricted to motion at constant velocity and applied forces parallel to the plane only Special Needs Addressed (please include activities for trainees with different learning abilities) - Teaching Aids/Resources (please indicate all external aids to be used in the lesson) 1. Smart board/White board 2. Engineering Science textbook N1 10 Minute s Introduction and Testing of Prior Knowledge 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. This article discusses work, energy and power in detail 90 Minute s Lesson Development/ Lesson Presentation (please do not list the content here, only note down activities and key words) Trainer Activities Trainees Activities Ask trainee what do they know about energy, work and power 10 Minute s Conclusion and Summary Work Definition-The work done by a force is defined to be the product of component of the force in the direction of the displacement and the magnitude of this displacement. Formula Work can be calculated by multiplying Force and Distance in the direction of force as follows W = F × d Unit The SI unit of work is the Joule (J) Energy Definition-Energy is defined as the capacity to do work. Formula The energy stored in an object due to its position and height is known as potential energy and is given by the formula: P.E. = mgh Unit The SI unit of energy is Joules (J). Power Definition-Power is defined as the rate at which work is done. Formula The formula for power is P = W/t, Unit The SI unit of power is Watt (W). Assessment Activities (Oral question) 1. What is the relationship between work, energy and power? 2. What happens to the energy as work is done? 3. What is the difference between work, energy and power? 4. Is energy transferred the same as work done? 5. How does work affect an object’s energy? 6. How are work, energy and power related to each other? 7. How are force, energy and work related? 8. What is the formula of work, energy and power? 9. How do you calculate energy from power? 10. Can force be converted into energy? Reflection
