WebIf the trashcan's velocity is constant, that means it has no net acceleration. If it has no acceleration, there is no net force on the object, since F=ma=4kg (0)=0. If there is no net force, then no net work is being done on the object, since W=fd=0 (2m). WebOne important phenomenon related to the relative strength of cohesive and adhesive forces is capillary action —the tendency of a fluid to be raised or suppressed in a narrow tube, or capillary tube. This action causes blood to be drawn into a small-diameter tube when the tube touches a drop. Capillary Action
