The value of the force is negative in that region, thus it points opposite to the displacement.esha said:
Right. As long as the force and displacement are in opposite directions, the work done by the force will be negative.esha said:
Work is a measure of the energy transferred to an object by a force. It is related to a graph by representing the area under a force vs. displacement curve.
You can calculate work from a graph by finding the area under the curve using the trapezoidal rule or by using the formula W = F*d, where W is work, F is force, and d is displacement.
The SI unit for work is joule (J), but other commonly used units include foot-pound (ft-lbf) and calorie (cal).
Yes, work can be negative if the force and displacement are in opposite directions. This indicates that work is being done against the force.
Yes, calculating work from a graph assumes that the force is constant and that the graph is a straight line. If the force varies or the graph is not a straight line, a more precise method of calculation is needed.
