Newton's third law plays an important role in connection with the normal force. In Figure 4.13, for instance, the block exerts a force on the table by pressing down on it. Consistent with the third law, the table exerts an oppositely directed force ...

Web1 de ago. de 2024 · This requires an increased normal force. When the elevator is accelerating downwards, it does not need to oppose gravity as much and so the normal force decreases to provide a net downward force from gravity. No changing mass is needed.

The person in an elevator isn't touching anything but the floor (which provides the normal force) and there is only one distance force (gravity). There can be no "external force" without contact with some other external object or another distance force.

Web27 de dez. de 2024 · Assume the block is in static equilibrium, i.e. Σ F → = 0 →. If you apply a force on the block that is less than the wight, i.e. F a p p < m g, then the block will not move. Since Σ F y = 0, then F a p p + N = m g N = m g − F a p p. Once F a p p > m g, then the normal force N = 0 and the block will begin to accelerate.
