Is work a vector or a scalar? Why?

Is work a vector or a scalar? Why?


Work is scalar, but work has positive and negative. The two necessary factors to do work are force and displacement. Force is vector and displacement is vector, but their product is scalar



Is power scalar or vector? Is power positive or negative? Is work scalar or vector?


Power is scalar, power has positive and negative, work is scalar, positive and negative



Vector or scalar
Is the work vector or scalar? If a small ball is thrown from a point and falls to the origin when it reaches a certain height, the work done by the air to it? (the distance from the origin to the highest point is h, and the air resistance is f)


Work is scalar, only magnitude, no direction, but positive and negative
