The discussion revolves around the concept of work in physics, particularly why work is considered to be zero when forces are perpendicular to the direction of motion. The subject area is primarily focused on mechanics and the work-energy theorem.
The discussion is ongoing, with participants seeking clarification on the concept of work and the role of the normal force. Some have suggested looking into the work-energy theorem for further understanding, while others are grappling with the implications of forces acting at right angles to motion.
Participants are working within the constraints of a homework assignment, indicating a need for clear explanations without advanced assumptions. There is a noted difficulty in understanding the basic principles involved.
The total work is zero, since the kinetic energy doesn't change. Look up the work-energy theorem.xtrubambinoxpr said:
The object is moving parallel to the the ramp, but the normal force acts perpendicular to it. So does the normal force do any work in this case?
