Work

Work  1. Work is delimitate as the product of the drill intensity level and the version of an physical object in the course of life of the utilise force.  2. W = F x S  3. W= operation make, F = force applied, S = displacement in the mission of force.  4. SI whole for reckon = joule (J), other unit = Nm  5. Work is not make 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 exertion is do to an object, competency is transferred to the object.  zero (Energy is the capacity to do have)  1. Energy exists in different forms: kinetic cleverness, gravitative authority ability, elastic possible push, sound strength, enkindle dynamism, light energy, electrical energy and chemic energy.  2. The unit for energy is Joule (J) same as work  3. The work dvirtuoso is equal to the sum of money of energy transferred.  4. energising 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 authority energy is the energy of an object due to its higher pip in the gravitational field.  a. E = mgh  b. M = mass, g = speedup due to gravity, h = height in metre  preservation 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 remain s the same.  3. When peeing falls from a d! am, its potential energy changes to kinetic energy.  4. When a swing moves from one mail service to another position, its potential energy changes to kinetic energy alternately.  position  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 neediness to get a all-encompassing essay, order it on our website: OrderCustomPaper.com
