How can energy be consumed when no work is done?
This energy comes from the chemical energy in your body and most of them are converted into heat and lost to the surrounding.
In this situation, no energy is transferred to the book, so no work is done.
You can feel the different energy consumption when your arm is stretched in different angle..
What is the formula for work done?
One can calculate the work done by an airplane by using the equation: W = F x D For instance, if a model airplane exerts 0.25 Newtons over a distance of 10 meters, the plane will expend 2.5 Joules.Work= F x D= 0.25 * 10= 2.5 Joules1 more row
What is transferred when work is done?
Work is the measure of energy transfer when a force ‘F’ moves an object through a distance ‘d’. So when work is done, energy has been transferred from one energy store to another, and so: energy transferred = work done. Energy transferred and work done are both measured in joules (J).
How does angle affect force?
As the angle that a force makes with the horizontal increases, the component of force in the horizontal direction (Fx) decreases.
What two factors affect the amount of work done on an object?
The amount of work done on an object depends on the amount of force exerted on the object and the amount of distance the object moves. According to Newton’s Second Law of Motion, the net force on an object is dependent on the mass of the object, and its acceleration during the movement.
How does angle affect work done?
If you apply force at an angle instead of parallel to the direction of motion, you have to supply more force to perform the same amount of work. … If you pull at an angle, the component of the force you apply that’s directed along the floor — in the direction of the displacement — does the work.
What are the 5 main factors that affect productivity?
The eight main factors that affect productivity are:Technical factors,Production factors,Organizational factor,Personnel factors,Finance factors,Management factors,Government factors, and.Location factors.
What are the factors that affects cooking?

What are the factors that affect work in physics?
The acting force on the body : Work is directly proportional to the acting force at constant displacement and constant angle between force and displacement . The displacement of the body : Work is directly proportional to the displacement at constant force and constant angle between force and displacement .
What are the factors that affect the performance?

How do you calculate work angle?
The angle theta in the equation is the angle between F and d. If the F is parallel to the incline and the d is parallel to the incline, then the angle theta in the work equation is 0 degrees. For this reason, W=F*d*cosine 0 degrees. In each case, the work is approximately 1.18 x106 Joules.
What is mean by work in science?
Work, in physics, measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement.
What is difference between work and energy?
There is a significant difference between work and energy. Work is the transferring of an amount of energy with the help of a force covering a particular distance through a direction. Energy is also referred to as the force which works at a certain distance. These both can be termed as scalar units.
How many types of energy are there?
6 FormsThe 6 Forms of Energy. There are many forms of energy: like solar, wind, wave and thermal to name a few, but the 6 Forms of Energy we study in Needham are: Sound, Chemical, Radiant, Electric, Atomic and Mechanical. Sound Energy- is produced when an object is made to vibrate.
What factors may affect how fast the work is done?
18 Factors Affecting Working PerformanceMenu items.Use of convenience foods.Type of service.Quantity of meals and number of meal periods.Facility layout and design and production equipment.Work environment and number of hours worked.
