PhySP18SS6.5.24 The work the normal force from the chair does on me as I stand up on the chair at a constant rate. Overall there was NO work done on the system. The normal Force did positive work, but while I am rising with no acceleration, there was no overall work being done. The normal force does positive work and gravity (mg) does negative work. ∑W = 0 Nm.
