Answer:
3rd law
Explanation:
First law of Newtons :
Newton's First Law states that, unless an external force acts on it, an object will remain in a straight line in rest or uniform motion.
The second law of Newtons :
The second law states that an object's acceleration depends on two variables-the net force that acts on the object and the object's mass.
The change in the linear momentum of the object is equal to the force.
Third law of Newtons :
This law states that every action has its reaction with the same magnitude but in the opposite direction.
When we push the wall , then the wall does not move because the wall is fixed but we skid opposite to the direction of applied force because wall offers an opposite force on our body.
Therefore the answer is "third law".
