The elevator floor does work on you as you stand in a rising elevator. In the jumping example, the floor is not doing work. After all, it is just a floor, it has nowhere to get the energy from to do work on you. (The floor of the elevator gets it from the motor running the elevator.)

For an object moving horizontally on a surface, the normal force is perpendicular to the direction of the displacement, so that the work done by it is zero. Web4 de ago. de 2024 · If the ball is inside a box, and the box is accelerating, of course something has to accelerate the ball, doing work. On the second example, normal force does not do work! Because on that logic gravity will do work, and it will exactly be in the opposite direction, counteracting the work by the normal force.

Nonetheless, Newton's laws still apply--that's where the so-called "work"-energy theorem comes from. In order for the man to accelerate, there must be an external force on him, which is friction. But that friction does no real work, thus does not …
WebNormal forces are not, as your elevator example illustrates, "perpendicular to the direction of motion", in general. They are perpendicular, but the perpendicularity in question - which is what the word "normal" refers to - is to the surface on which the object is in contact with. … in and out burger stickersWebThe farther the two vectors get from parallel, the less work is done. Expand the angle beyond 90°. Force and displacement are starting to point in opposite directions. At 90°, no work was done. Beyond 90°, less than no work must be done. This is negative work.
