Explanation:
When a drill bores a hole in a piece of wood, it demonstrates both translator and rotatory motion.

Translator Motion:
Translator motion is the motion in which an object moves in a straight line. When a drill bores a hole in a piece of wood, it moves in a straight line along the axis of rotation. The drill moves forward in a straight line to penetrate the wood and create a hole. This is an example of translator motion.

Rotatory Motion:
Rotatory motion is the motion in which an object moves around an axis. When a drill bores a hole, it rotates around its own axis. The drill bit spins rapidly, creating a circular motion. The rotation of the drill bit allows it to cut into the wood and create the hole. This is an example of rotatory motion.

Combination of Translator and Rotatory Motion:
In the case of a drill boring a hole in a piece of wood, both translator and rotatory motion are involved. The drill moves forward in a straight line (translator motion) while also rotating around its axis (rotatory motion). The combination of these two motions allows the drill to penetrate the wood and create a hole.

Importance of Translator and Rotatory Motion:
The combination of translator and rotatory motion is essential for drilling holes in various materials. Translator motion allows the drill to move forward and penetrate the material, while rotatory motion enables the drill bit to cut into the material effectively. Without these two motions, it would be challenging to create holes using a drill.

In conclusion, when a drill bores a hole in a piece of wood, it demonstrates both translator and rotatory motion. The translator motion allows the drill to move forward in a straight line, while the rotatory motion enables the drill bit to rotate and cut into the wood. This combination of motions is crucial for drilling holes efficiently.
