Question

The force exerted by the floor of an elevator on the foot of a person is _______ the weight of the person if the elevator is going up and speeding up.

Answer 1

Hint: Given that the elevator is going up and speeding up and so this shows the situation of the positive acceleration of an object. So, applying the fundamental will fill in the given bracket.

Complete answer:
The positive acceleration can be defined as the increase in velocity with time. The velocity is expressed in the same direction with the acceleration when an object is speeding up. And so, the object is supposed to have the positive acceleration.Since, the elevator is speeding up the force exerted is more than the weight of the person creating the acceleration to be in the upward direction and positive.For example: A satellite accelerated up towards space, Escalators moving upward.

Hence, the force exerted by the floor of an elevator on the foot of a person is more than the weight of the person if the elevator is going up and speeding up.

Note: The above example suggests that the normal force exerted by the floor of the elevator on the person is greater than the weight of the person. It is expressed as the \[N > mg\].
