When we punched on a wall we get hurt? Why

Expert Answer:

Newton’s third law of motion states that if an object exerts force on another object then the second object exerts an equal and opposite force on the first object.
The wall is stronger and rigid. So, when we punch a wall, it applies an equal and opposite force. Hence, we get hurt.
