Question

Find at least one example of each case from everyday experiences (a) a situation where normal force on a person is equal to the person's weight, (b) a situation where normal force on a person is greater than the person's weight, and (c) a situation where normal force on a person is less than the person's weight. Also, can you find an example which covers each of all three cases, depending on changing

Answer 1

a) for the normal force to be greater than person's weight

while walking on the horizontal road or standing

the normal force is equal to person's weight

b)

for normal force on a person is greater than the person's weight

while in a car , moving in a valley , at the bottom of valley

the normal force is greater than the person's weight

c) while in a rollercoaster , at the top of loop

the normal force acting is less than the weight of the person

==========================

for one example that covers all three

while traveling in a lift

while accelerating upwards (Normal force is more than weight)

while moving with constant velocity (normal force is equal to weight)

while decelerating while moving upwards (normal force is less than weight of person )
