In this cell you see the guy say that he is going to carry the larger box.
I'll take this one!
This...this ain't it chief
I'll take this one.
In this cell you see the guy struggling to push the box because it has a high mass and he is not using enough force to move it. The box does not have a high acceleration.
BOY IF YOU DON'T-
In this cell, the guy asks for help from the girl so that the amount of force used can be increased creating an unbalanced force. Before the force was balanced which is the reason the box remained in its spot.
I'm trying! The box is just really heavy. Can you help?
YOU NEED TO PUSH IT HARDER! HURRY UP I NEED TO LEAVE SOON AND YOU NEED TO DROP ME HOME!
In this cell, both the characters are using force to increase the acceleration of the box. They do this by pushing the box, creating an unbalanced force.
why did I agree to this
This cell has nothing to do with Newton's law.
Took you long enough.
Newton's second law claims that the acceleration of an object relies on the objects mass and the force used to move it.
