we know that work done

W = F . d . cosA

where A is the angle between Force and Displacement(d)...

If A=0 that means F & d are in same direction.. W=positive...!

If A=1800, that implies that F & d are in opposite directions... W=negative!

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.


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.


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.


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.


In order for work to be done on an object the object has to move and?

force has to be applied to it. Work is calculated by multiplying the force applied to the object by the distance the object moves in the direction of the force. Without both force and movement, no work can be done on an object.


When a force is exerted on an object work is done only if the objec?

moves in the direction of the force. If the object does not move in the direction of the force, then no work is done on the object.


Where do you say that work is done an object?

Work is done on an object when a force is applied to the object and the object moves in the direction of the force. The work done is calculated as the product of the force applied and the distance the object moves in the direction of the force.


Distinguish cases when work is done and when it is not?

The cases when work is done and when it is not are quite distinct. Where work is done, the task is completed to satisfaction but where it is not, it means it has either not been started or it has been done below standard.


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 a force is applied that moves an object in the direction of the applied force what is done?

When a force is applied to an object in the direction of the force, work is done on the object. Work is defined as the product of the force applied and the distance over which the force acts in the direction of the force. Therefore, when an object is moved in the direction of the applied force, work is performed on the object.


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.


What conditions must be met in order for work to be done?

1 there must be movement 2. there must be force 3. the force and satnce the object travels must be in the same direction
