Final answer:
Carpenters tighten the head of a hammer onto the handle to prevent it from detaching during use. This can be explained using Newton's first law of motion, which states that an object at rest will stay at rest, and an object in motion will stay in motion, unless acted upon by an external force. The force exerted by the carpenter's hand on the hammer's handle pushes against the head, preventing it from detaching.
Step-by-step explanation:
By tightening the head of a hammer onto the wooden handle, carpenters ensure that the hammer's head remains securely attached during use. This can be explained using Newton's first law of motion, also known as the law of inertia.
Newton's first law states that an object at rest will stay at rest, and an object in motion will stay in motion, unless acted upon by an external force. In the case of the hammer, the force exerted by the carpenter's hand while using the hammer causes the handle to push against the head, preventing it from detaching.
This action is similar to how a seatbelt in a car works. When a car suddenly stops, the seatbelt prevents the passengers from moving forward due to the force of inertia. Similarly, tightening the hammer's head onto the wooden handle applies a force that keeps the head from detaching.
