When you push against a wall with your fingers, they bend because they experience a force. Identify this force.
The force, when you push against a wall with your fingers, they bend.
Answer to Problem 1RCQ
Solution:
When we push against a wall with our fingers, they bend because as per Newton’s third law, every action has an equal and opposite reaction. When we exert some force on the wall, our fingers will also experience a force opposite to the force applied so it bends.
Explanation of Solution
As per Newton’s third law, when we push or pull any surface or any object, the reaction force of our push or pull will act upon us in the opposite direction. This opposite force is known as Reaction Force.
Here, in the above example, when we push against the wall with our fingers then the wall pushes back at us with the same force. Due to this reaction force, our fingers tend to bend.
Conclusion:
So as per the above explanations, we can conclude that all forces in nature exist in the form of an action-reaction pair. So if we push or pull any system or object with some force then that system or object will act against us with the same force in the opposite direction.
So here, in all the cases like when we jump out of the boat then we also push the boat with the same force in the opposite direction and hence the boat goes backward. In many other examples, we can observe the same that all forces exist in an action-reaction pair.
