Gravity aids in both hammering a nail in and pulling it out by providing an additional force through its downward pull.
Gravity makes it easier to hammer the nail into the board as it provides a downward force that assists in driving the nail deeper. When the hammer strikes the nail, gravity pulls the hammer down, increasing the force on the nail and aiding in its penetration into the wood.
In the scenario of pulling the nail out using a claw hammer, the same principle applies. Gravity assists in pulling the nail out of the wood when the hammer is used to apply force in the same direction. The force exerted in combination with gravity helps in leveraging the nail out more effectively.
Therefore, gravity plays a crucial role in both hammering a nail into a board and pulling it out, enhancing the efficiency of the process.
