Newton's second law of motion
T=M(g+a)T = M(g + a)T=M(g+a)
N=m(g+a)N = m(g + a)N=m(g+a)
Normal force NNN exerted by lift floor
N=mgN = mgN=mg (equals actual weight)
N=m(g+a)N = m(g + a)N=m(g+a) (increases, feels heavier)
N=m(g−∣a∣)N = m(g - |a|)N=m(g−∣a∣) (decreases, feels lighter)
N=0N = 0N=0 (weightlessness)
