The only time that you realize that something is going on is when that elevator is really just accelerating or when it's just decelerating. It's going to be 10 kilograms times the acceleration of this toddler, times 2 meters per second squared, which is equal to 20 kilogram meters per second squared, which is the same thing as 20 newtons upwards. The net force is going to be the mass of this toddler. This is because the normal force is generated to counter the downward forces pushing against the floor. If they have no acceleration in any direction, and we're only concerning ourselves with the vertical direction right here, that means that there must be no net force on them.

B) The normal force is smaller than the weight, because the rope supplies an upward force of 11 N that partially supports the box. The coefficient of kinetic friction between rubber and the pavement is about 0. Normal force in an elevator (video. Is there mistake in my logic or is there a mistake in video? However, in certain situations the force of gravity is equal to the net force: => Where.

I know that if the acceleration of the lift in downward direction is 9. Let me-- oh, this is 2 meters per second squared. Colonel John Paul Stapp of the US Air Force did several experiments, strapping himself to a rocket sled, and determined that 32 g was an acceleration someone could walk away from, which then became the acceleration used in the design of fighter jet seat. But if the acceleration is 10m/s^2 then we get the normal force to be -2N. From what I've learned, normal force on a horizontal surface must be equal and opposite to the applied force, so I don't think it is the normal force which is accelerating the toddler.
