Is force perform works?
Only if there is also a movement. Work done by a force can be calculated as force x distance. This is assuming the force and the movement are in the same direction.Only if there is also a movement.

When you apply force at an angle to the direction of movement of the force does work?
When you apply force at an angle to the direction of movement, two components result; F.D + FxD. F.D = -FDcos(angle) called work and FXD = FDsin(angle) called torque.
How do we know if work is done?
Work is done when a force is applied to an object and it causes the object to move in the direction of the force. The work done is equal to the force applied multiplied by the distance the object moves in the direction of the force. If there is no movement or the force is not in the direction of movement, then no work is done.
Why are you doing work when you lift something but not when you carry it?
Its just due to the "physical" definition of work. In order for a force to do work on an object it must move (at least some component of it) parallel to the force. So when lifting, the force is up and the movement is up and the force does work. In carrying, the force is up but the movement is horizontal. They are perpendicular and the force does no work. False
What determines whether or not work is being done?
Work is done when a force is applied to an object and it causes the object to move in the direction of the force. Mathematically, work is calculated as the force applied multiplied by the distance the object moved in the direction of the force. If there is no movement or if the force is not in the same direction as the movement, then no work is being done.
Does centripetal force do work on the particle on which it acts?
No, because the force is perpendicular to the movement.
What is the combination of force and movement?
Simple!! Its work done. W = F x D where, D is displacement. F is Force applied. W is Work done.
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.
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.
Why isn't work done as you hold a book motionless over your head?
Work is the product of force and displacement in the direction of the force. When holding a book motionless over your head, the force applied is vertical while the displacement is zero. Therefore, no work is being done as there is no movement in the direction of the force.
How is it possible to apply force to something but do no work?
Work is calculated as force multiplied by the distance the force is applied over. If the force is applied but the object does not move, no work is done because there is no displacement. So, it is possible to apply force without doing work if there is no movement of the object.
Work is done when only what is applied?
Work is done when a force is applied to an object and the object moves in the direction of the force. It is calculated by multiplying the force applied by the distance the object moves in the direction of the force. If there is no movement, then no work is done.
