F = m A
when at rest.
Force down on floor =weight = m g
Force up from floor on shoes = m g
Force up - Force down = 0 so A = 0
when accelerating upward the force up from floor on shoes must be greater thsn the force down, m g
Fup - m g = m A
so
Fup = m g + m A
when at rest.
Force down on floor =weight = m g
Force up from floor on shoes = m g
Force up - Force down = 0 so A = 0
when accelerating upward the force up from floor on shoes must be greater thsn the force down, m g
Fup - m g = m A
so
Fup = m g + m A
