) While an elevator traveling upward slows down to stop, the normal force on the feet of a passenger is her weight. While an elevator traveling downward slows down to stop, the normal force on the feet of a passenger is his weight.

1.FN = mg-ma

2.FN =mg+ma

Explanation:

when we are in elevator and its moving upward we feel heavier because of gravity as we are moving up and its is attracting us down. FN is normal force of a body, and FN=mg-ma is more than actual weight.

when we are moving down the normal force on passenger feet is mg+ma as  it is deacclerating and we will feel our normal weight and nothing is affecting us.
