according the graph sown, the net force acting on an object varies wth the object's displacement.calculate the work down by the force on the object at the various displacements listed below (i won't bother telling you since you don't have a graphy, but I figured out the work done to be these) its the second part of the question that I don't understand:
a)the work down = 160J
b)200J
c)480J
"state to possible outcomes of the work above being done on the object.
Please explain!
To calculate the work done by a force, you need to multiply the force applied to an object by the displacement it undergoes in the direction of the force. In this case, since you haven't provided a graph, I'll assume you have a table with the corresponding displacements and the net force acting on the object at those displacements.
To calculate the work done at each displacement, you simply multiply the net force at that displacement by the corresponding displacement value given in the table. Let's go through each case:
a) Work done = 160 J
Multiply the net force at that displacement by the corresponding displacement value to get 160 J:
Work = Force x Displacement
b) Work done = 200 J
Multiply the net force at that displacement by the corresponding displacement value to get 200 J:
Work = Force x Displacement
c) Work done = 480 J
Multiply the net force at that displacement by the corresponding displacement value to get 480 J:
Work = Force x Displacement
Now, regarding the possible outcomes of the work being done on the object:
The work done on an object can have two possible outcomes:
1) Positive work: When the force applied on an object is in the same direction as the displacement of the object, positive work is done. In this case, the object gains energy.
2) Negative work: When the force applied on an object is in the opposite direction of the object's displacement, negative work is done. In this case, the object loses energy.
The sign of the work done depends on the angle between the direction of the force and the direction of displacement. If the force and displacement are in opposite directions, the work is negative. If they are in the same direction, the work is positive.
Without further information about the relationship between the net force and displacement, as well as the direction of the force, it is not possible to determine whether the work done on the object is positive or negative in each case.
