How does a book work?
work can only be done by a living being
What is the only condition that work is done?
Work is done when a force is applied to an object and the object moves in the direction of the force. If there is no movement, no work is done, even if a force is applied.
Is holding a pencil work or not?
No, work is only done when an object is moved.
How much work is done by a force of 500N on a stationary brick wall?
No work is done on the brick wall by the force of 500N because the wall does not move in the direction of the force. Work is only done when a force causes a displacement in the direction of the force.
Do all forces of an object cause work to be done?
No, work is only done by a force when there is displacement in the direction of the force. Forces that do not cause any displacement, such as static friction or normal force, do not do work on an object.
Is any work done by pushing wall?
No, pushing against a wall does not result in any work being done. Work is only done when a force causes an object to move in the direction of the force, so if the wall does not move, no work is done.
If you push a box forward and the box moves forward you have done how much work?
You have only done as much external work on the box as the distance it moves: work = force x distance. If it does not budge no work is done on the object. You have done "internal" work on your muscles which converts to heat energy, but technically speaking, no external work is done on the object
What is the work- energy theorem?
The work done by the net force acting on a body results change only in its kinetic energy.The work done by the net force acting on a body results change only in its kinetic energy.
If an object is being pushed but does not move is there any work being done on the object?
No, work is only done on an object when there is displacement in the direction of the force applied. If the object does not move, then no work is being done on it.
Is work done when a force is a applied to a mass but the mass does not move?
No, work is not done if the force is applied to a mass but the mass does not move. Work is only done when a force causes a displacement in the direction of the force being applied.
Is work done every time forces are exerted on an object?
No, work is only done if the force causes the object to move in the direction of the force. If the force is exerted but the object does not move, no work is done. Work is calculated as force multiplied by the distance the object moves in the direction of the force.
Is work is always done when force is applied?
Work is only done when a force causes a displacement in the direction of the force. If the force is applied but there is no movement or displacement, then no work is done. Work is calculated as force multiplied by the distance moved in the direction of the force.
