But when the object slides then the friction force is constant and equal to T = μ N and is is always opposite to the velocity of the body. So then W T = − T s where s is the total space traveled by the body. Share. how to set up a virtual visit https://v-harvey.com

Web1 de ago. de 2024 · Solution 1. In the elevator example, you are correct. 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.) Web17 de fev. de 2024 · Symbol of normal force: F. Unit of normal force: Newton or N. Dimensions of normal force: MLT -2.

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.
