Normal force in an elevator
WebExample - Force and Power to Lift an Elevator. An elevator with mass 2000 kg including passengers are moved from level 0 m to level 15 m. The force required to move the elevator at constant speed can be calculated as. F c = (2000 kg) (9.81 m/s 2) = 19820 N. The power required to move the elevator between the levels in 20 s can be calculated as WebEver wonder why you feel lighter or heavier in an elevator?

WebThe normal force is the push that a surface (or object) exerts back on an object that comes into contact with it. The normal force always acts perpendicular to, and away from, the surface. The name "normal" literally means perpendicular. This principle is very important to remember when solving problems that involve the normal force.
