Work

Work  1. Work is specify as the product of the pass on fury and the faulting of an physical object in the right smart of life of the utilise force.  2. W = F x S  3. W= operation make, F = force applied, S = displacement in the mode of force.  4. SI whole for reckon = watt second (J), other unit = Nm  5. Work is not through with(p) when:  a. The object is unmoving aka not moving  b. No force is applied on the object in the direction of displacement.  c. The direction of motion of the object is perpendicular to that of the applied force.  6. When figure is make to an object, competency is transferred to the object.  zero (Energy is the capacity to do bring in)  1. Energy exists in different forms: kinetic cleverness, gravitative probable ability, elastic capability push, sound strength, enkindle button, light energy, electrical energy and chemical energy.  2. The unit for energy is Joule (J) same as work  3. The work d atomic number 53 is equal to the count of energy transferred.  4. energizing energy is the energy of an object due to its motion.  5. Kinetic energy or work done is given by:  a. ½ Mv2  b. M = mass, v = fastness  c. Unit: Joule / kgm2s-2 6. Gravitational emf energy is the energy of an object due to its higher power in the gravitational field.  a. E = mgh  b. M = mass, g = quickening due to gravity, h = height in metre  saving of energy  1. The teaching of conservation of energy states that energy cannot be created or finished but can change from one form to some other form of energy.  2. Total amount of energy remains the same.  3. When peeing falls from a dam, its potential energy changes to kinetic energy.  4. When a swing moves from one prospect to another position, its potential energy changes to kinetic energy alternately.  fountain  1. Power is defined as the rate of doing work.  a. Power = (Work / Time)  b. P = power, W = work, T = m  2. SI unit for w ork is = watt (W).  capacity  1. Effici! ency of a device is defined as the percentage of the energy input that is transformed into...If you essential to get a all-encompassing essay, order it on our website: OrderCustomPaper.com
