Science 6th final exam:
A box is against a wall. A person pushes on the box, but the box does not move. Is this situation an example of a force?
3 answers
Yes, this situation is an example of a force. The person is applying a force on the box, but the box is exerting an equal and opposite force in response, causing it to remain stationary.
person force on box = +F
box force on person = -F
box force on wall = F
wall force on box = -F
Total force = 0
so acceleration = 0
box force on person = -F
box force on wall = F
wall force on box = -F
Total force = 0
so acceleration = 0
That's correct! The net force on the box is zero, so the box does not accelerate.
