What are some examples of work not done?
Work is said to be done where certain displacement is involved. Ex. Of work not done is Coolie carrying Load on his head..
Is work done if you push a car that has run out of gas?
Yes. The work is being done by whoever is pushing rather then the engine, but work is being done. Any time a force is applied through a distance, work is being done.
How do you calculate work done on an object .?
The equation to calculate the work done is: Work done (J) = force applied (n) x distance moved of force (m)
Is this true......Work output is the work done by a machine?
correct
Is work being done when you pick your pencil up from the floor?
Of corse,potential energy of pencil is increased.Therefor work done
What is transferred to an object when work is done?
Energy
What is the transferred to an object when work is done?
When work is done on an object, energy is transferred to the object. This can result in a change in the object's motion, position, or internal energy.
How much work is done with 200N of force in unsuccessful effort?
Work = force x distance. If the object doesn't budge, no energy is transferred (no work is done). Some energy may be wasted, but no work is transferred.Work = force x distance. If the object doesn't budge, no energy is transferred (no work is done). Some energy may be wasted, but no work is transferred.Work = force x distance. If the object doesn't budge, no energy is transferred (no work is done). Some energy may be wasted, but no work is transferred.Work = force x distance. If the object doesn't budge, no energy is transferred (no work is done). Some energy may be wasted, but no work is transferred.
How does doing work on an object change its energy?
When work is done on an object, energy is transferred to or from the object, changing its energy. If work is done on an object, its energy increases; if work is done by an object, its energy decreases. The change in energy of an object is equal to the work done on it.
Is power a measure of work?
No, power and work are related but not the same. Power is the rate at which work is done or energy is transferred, while work is the energy transferred when a force causes an object to move over a distance. Power is a measure of how quickly work is done.
How is energy and work related?
Energy is the ability to do work, and work is the transfer of energy. When work is done on an object, energy is transferred to that object, causing it to move or change. The amount of work done is directly related to the amount of energy transferred.
Why can't the work done by a machine be greater than the work done on the machine?
According to the law of conservation of energy, energy cannot be created or destroyed, only transferred. Therefore, the work done by a machine cannot be greater than the work done on it because the input work is what provides the energy for the output work. Any excess work would violate this principle.
Is it true that energy is transferred when work is done?
Yes, when work is done on an object, energy is transferred to that object in the form of mechanical energy. Work is the transfer of energy that results in a displacement of an object in the direction of the force applied.
What is measured in watts or kilowatts?
The rate at which work is done, or energy is transferred or dissipated.
What is work done on a machine called?
The work done on a machine is called input work or mechanical work. It refers to the energy transferred to the machine to operate it and perform tasks.
Power is work done over a distance?
Power is the rate at which work is done or energy is transferred. It is calculated as the work done divided by the time taken to do the work. Power is measured in watts (W) or joules per second (J/s).
Is work done a scalar or a vector quantity?
Work done is a scalar quantity, meaning it has magnitude but no specific direction. It is measured in joules, which represents the amount of energy transferred by a force acting over a distance.
