Were you able to fix that problem?
Answer: a force is simply a push or pull.
The SI unit for force is Newton(N) or kgm/s2
When the net force on an object is not zero the forces are said to be unbalanced since they do not cancel out each other .
When two forces act in opposite directions we substract the forces in order to get the resultant force acting on the object.
Explanation:
It will most likely expand when hot and contract when cold.
