### If work is a scalar measurement, why do we sometimes represent it as the product of force (a vector) and distance (scalar)?

Work is the dot product of a vector force and a vector displacement, hence a scalar. Knowing just the scalar distance isn’t enough to calculate work. That distance might be in the same direction as ...

### Why doesn't constant acceleration give me total displacement?

The (signed) area under the velocity-time graph, shaded in red, is the displacement. What you think is happening: What actually happens: So the reason is that the velocity is changing continuously ...

### If application of force does not result in spatial movement, has work been done?

No. No work would be done in this case, at least not at the macroscopic level. Work is the product of force and displacement in the direction of the force and in this case there is no displacement. ...

### Can distance traveled by a body be zero?

Distance traveled refers to the total length of the path taken by an object, regardless of direction. Scenarios: If an object remains stationary (doesn't move), the distance traveled is zero. If an ...
