The force of gravity acts on a 4.00 kg object as it moves from the origin (position O) to position C with coordinates x = 6.96 m and y = 8.70 m as shown in the figure. Determine the work done on the object by the force of gravity as the object moves from position O to C along the following paths. (Include the sign of the values in your answers.) path OAC How may we determine the work done by a constant force acting over some displacement? Is work a scalar or vector quantity? path OBC How may we determine the work done by a constant force acting over some displacement? Is work a scalar or vector quantity? path OC How may we determine the work done by a constant force acting over some displacement?
