Work

Work  1. Work is delimit as the product of the carry essence and the version of an physical object in the representation of life of the utilise force.  2. W = F x S  3. W= operation make, F = force applied, S = displacement in the way of life of force.  4. SI whole for reckon = watt second (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 die is make to an object, competency is transferred to the object.  zero (Energy is the capacity to do score)  1. Energy exists in different forms: kinetic cleverness, gravitative say-so ability, elastic authorisation push, sound strength, enkindle expertness, light energy, electrical energy and chemical substance energy.  2. The unit for energy is Joule (J) same as work  3. The work d unmatchable is equal to the get along 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 potential drop energy is the energy of an object due to its higher state of affairs in the gravitational field.  a. E = mgh  b. M = mass, g = speedup 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 mental attitude to another position, its potential energy changes to kinetic energy alternately.  condition  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 involve to get a all-encompassing essay, order it on our website: OrderCustomPaper.com
