Physics definition of work:
(force applied ) multiplied by (distance through which the force acts).
In the scientific definition of work, magnetic and electric fields can do work on charged particles that are moving through them. The work done is based on the force exerted by the field on the particle and the distance over which the particle is displaced.
Work is done when a force causes an object to move through a distance. The amount of work done is calculated by multiplying the force applied by the distance the object moves in the direction of the force. If the force and the displacement are perpendicular to each other, work done is zero.
In order for work to be accomplished according to the scientific definition, a force must be applied to an object, causing it to move in the direction of the force. Work is done when this force causes the object to be displaced.
Work can be calculated by multiplying power by time. The formula is: Work = power × time. This equation is derived from the definition of power, which is the rate at which work is done over time.
No, the work done in moving a body does not depend on how fast or slow the body is moving. The work done is determined by the force applied and the distance over which the force is applied, not the speed of the body.
work done
a piece of work to be done or undertaken.
A site where work is being done.
amount an employee receives for work done.
work assigned by a teacher that is to be completed at home The definition for homework is just simply work that is done at home. Its a review of what you did in school that day.
Work to be done "scientifically" the product of Force and Displacement (FD) must be other than zero.
If you mean "work" in the way it is used in physics, the basic definition of work is force x distance. In other words, if you apply a force over a certain distance, work is done.
This is the definition of power (measured in Watts). Power= Work/Time
The definition of evisceration is to remove the entrails or disembowel. This is done by an incision made across the abdomen. You can learn more about Evisceration at the Wikipedia.
Answer: It depends upon your definition of "work". Assuming the lifter put the barbell back exactly where and how it was at first, then there was no work done in the physics context. If you mean manual labor, then yes, some work was done.
In the scientific definition of work, magnetic and electric fields can do work on charged particles that are moving through them. The work done is based on the force exerted by the field on the particle and the distance over which the particle is displaced.
the efficiency of a heat engine measured by the ratio of the work done by it to the heat supplied to it.
