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. Web31 de jan. de 2024 · But I don't at all understand how you will feel an upwards force of -0.5g when an elevator is accelerating downwards. Because when in an elevator, accelerating downwards at theoretically $4.9m/s^2$, the force normal will still be upwards (as it's preventing free fall), but will be less than if there was no acceleration (less weight).
