How do you know if the movement of the object is in the same direction of the force for work done?

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!

Which activity describes work being done on an object?
A person pushing a box across a floor:· Mass of box = 20 KG, Weight of Box = 196.2· Distance moved in the direction of the force = 2m· Work Done = Force X Distance ( in the direction of the force), 196.2 X 2= 392.4 Joules
How do we know if work is done?
In physics, work is done by a force acting on an object if the object moves in the direction of the force.
How much work is done by a force 10N IN moving an object through a distance 1m in direction of force?
Simply multiply force x distance. This assumes that the force is in the same direction as the movement.
What conditions must be met for work to be done?
1. A force is needed 2. The point of application of the force is to be displaced. 3. If the displacement is in the direction of the force then work is said to be done by the force and if the direction of displacement is opposite to the force then work is done against the force.
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.

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

What does an object need before it can perform work?
In order for work to be done on an object, the object must move some distance as a result of your force.
When can use say that work is done?
Work is done when a force is applied to an object which moves in the direction of the force.
When force and motion are going in the same direction is work being done?
When force is opposite to the direction of motion, no work is done. The object to which the force is applied must move in the direction of the force in order for work to be done.
What two things need to happen for there to be work done on an object?
If he object moves as a force is applied and the direction of the objects motion is the same as the direction of the same force.
How is work done by a force measured when force is in direction of displacement?
Work = (force on an object) times (displacement of the object during the time the force is applied to it).
What is difference between work motion and force?
motion is the movement of an object and force is the power or work done to move the object
