When you place your ear on the desk and listen to the sound of pencil tapping, that sound becomes amplified because the desk acts as a resonating chamber. When you lift your ear off the desk and listen to the tapping in the air, the sound may seem quieter or different because there is less direct contact with the surface to amplify the vibrations.
Gravity pulls the pencil downward towards the desk, creating a force that helps keep it balanced when not being moved by an external force. Other factors, such as the friction between the desk and the pencil, also play a role in keeping it stable.
A pencil getting knocked off the desk is an unbalanced force. The force of the object hitting the pencil is greater than the force of gravity keeping it on the desk, causing it to fall.
The pencil resting on a desk has potential energy due to its position in the gravitational field.
The force needed to move a pencil across a desk would depend on the friction between the pencil and the desk surface. If there is low friction, only a small force would be needed. If there is high friction, a greater force would be required to overcome it.
The force required to lift a pencil off a desk is the gravitational force acting on the pencil. When you lift the pencil, you are exerting an upward force that overcomes the force of gravity pulling the pencil downward.
Tapping: you bouncing your pencil point or your finger on a desk. Taping: you using tape to wrap a present.
Why this is in the jokes and riddles section is beyond me. Anyhow, when a student taps his pencil on a desk, the impact causes the pencil and the desk to vibrate. This vibration also causes the air to vibrate, and vibrations in the air = sound!
It's a question asking: Is there a pencil on the desk. Usually means in the desk, so it would be: Is there a pencil in the desk.
Sound is a form of energy that travels in waves known as compression waves or waves that are compacted by pressure. Sound can travel in many mediums such as solids, gas, and water. Most importantly is the presence of molecules in our atmosphere for sound cannot be heard in the vacuum of space. So, when you tap your pencil on your desk, you are creating a vibration that can be heard. The harder you tap, the louder the sound will be.
I have a pencil in (meaning on) my desk. Tengo un lapiz en mi escritorio/pupitre/carpeta (alternatives for 'desk') I have a pencil in[side] my desk Tengo un lapiz dentro de mi escritorio.

It is called the mechanical pencil!
probably at his desk.
on the desk :-D
ht now, my teacher is annoyingly tapping on her baige, wooden desk
