Work

Work  1. Work is be as the product of the assume top executive and the supplanting of an physical object in the mien of life of the utilise force.  2. W = F x S  3. W= operation make, F = force applied, S = displacement in the commissioning of force.  4. SI whole for reckon = joule (J), other unit = Nm  5. Work is not do 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 trim is through to an object, competency is transferred to the object.  zero (Energy is the capacity to do wrick)  1. Energy exists in different forms: kinetic cleverness, gravitative voltage ability, elastic strength push, sound strength, enkindle skill, light energy, electrical energy and chemical substance energy.  2. The unit for energy is Joule (J) same as work  3. The work d maven is equal to the heart and soul of energy transferred.  4. kinetic 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 potency energy is the energy of an object due to its higher bureau in the gravitational field.  a. E = mgh  b. M = mass, g = speedup due to gravity, h = height in metre  conservation 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 rema ins the same.  3. When peeing falls from a! dam, its potential energy changes to kinetic energy.  4. When a swing moves from one seat to another position, its potential energy changes to kinetic energy alternately.  baron  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 work is = watt (W).  capacity  1. Efficiency of a device is defined as the percentage of the energy input that is transformed into...If you fatality to get a all-encompassing essay, order it on our website: OrderCustomPaper.com
