Please help me its our prelim exam today. Static friction acts when the surfaces are not in relative motion against each other. An elevator stopped on the third floor.

Normal force up and perpendicular to the incline. A when there is friction acting on something it makes it harder to move the object so it would require more tension force to move the box B M1 will not be accelerating as fast in case two than in case one because there is the extra force of friction acting against mass 1. Diego uses a pulley system and gives a big lift to the pianoThe piano moves upward then stops and then it starts to fall to the ground.
