According to the third law of motion when we push on an object, the object pushes back on us with an equal and opposite force.
If the object is a massive truck parked along the roadside, it will probably not move.
A student justifies this by answering that the two opposite and equal forces cancel each other.
Comment on this logic and explain why the truck does not move.

A student justifies this by answering that the two opposite and equal forces cancel each other.
Comment on this logic and explain why the truck does not move.
The static friction between the road and the truck is because the truck has a very high mass. When pushing the truck with a small force, the frictional force the applied force and the truck . This suggests that the two forces are in magnitude but in direction.
Therefore, the student’s logic is .
