Is work done by normal force always zero? - Quora

Web9 de out. de 2005 · I think I will answer the task by saying: " Friction can't do positive work, because: (1) In the case of kinetic friction: Kinetic friction always oppose motion so. W = F*d*cos (x>90 degrees) = - F*d. (2) In the case of static friction: Their is no displacement and therefore no work is done.

The normal force is the force that keeps us from falling to the center of the earth. Every surface or object we stand on exerts a force back on us. Otherwise, we would fall through the object/surface due to the force of gravity. The normal force is a reaction force, and as such has no formula specific to it. chinese food pacific mo

"WebThe general formula for work and for determining the amount of work that is done on an object is: W = F × D × cos (Θ) where W is the amount of work, F is the vector of force, D is the magnitude of displacement, and Θ is the angle between the vector of force and the vector of displacement.

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 …

WebThe 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. Apply less than no force → Do less than no work
