# Force with zero acceleration [duplicate]

If I apply a force on a body which is kept against a wall, then the body will not move. The body is not moving means that its velocity is zero, and hence its acceleration is also zero. According to Newton's second law of motion, $$\ F = ma$$ If the acceleration is $0$, then $F = 0\ \text N$. It means that I'm not applying any force on the body, but how can it be if I'm pushing my hands against the body?

Possibly, You don't need an object between you and the wall. But simply, the same thing happens if you push the wall. –  Waffle's Crazy Peanut Mar 25 '13 at 14:38
