  3. Normal force - Wikipedia

    en.wikipedia.org/wiki/Normal_force

    Figure 2: Weight (W), the frictional force (F r), and the normal force (F n) acting on a block.Weight is the product of mass (m) and the acceleration of gravity (g).In the case of an object resting upon a flat table (unlike on an incline as in Figures 1 and 2), the normal force on the object is equal but in opposite direction to the gravitational force applied on the object (or the weight of ...

    A paternoster in Prague Paternoster elevator in The Hague, when it was still in operation. A paternoster (/ ˌ p eɪ t ər ˈ n ɒ s t ər /, / ˌ p ɑː-/, or / ˌ p æ-/) or paternoster lift is a passenger elevator which consists of a chain of open compartments (each usually designed for two people) that move slowly in a loop up and down inside a building without stopping.

  5. Apparent weight - Wikipedia

    en.wikipedia.org/wiki/Apparent_weight

    Another example is the weight of an object or person riding in an elevator. When the elevator begins rising, the object begins exerting a force in the downward direction. If a scale were used, it would be seen that the weight of the object is becoming heavier because of the downward force, changing the apparent weight. [3]
