Mechanical pencils themselves do not need any energy in the forms of battery or electricity. However, mechanical pencils do need human energy to work. We need to add lead and push lead out; they do not do this on their own.
Mechanical pencils, like the regular kind of pencils, use graphite.
Clocks, watches, cars, bicycles, guns, toilets, chainsaws, your body, locks, clicky pens, mechanical pencils, trains, most multicelular organisms use mechanical energy for movement and things like that, what doesn't have mechanical energy in it?
A pencil sharpener itself is not considered mechanical energy. Mechanical energy refers to the energy associated with the motion and position of an object, while a pencil sharpener is a tool that uses mechanical components to sharpen pencils by grinding the pencil tip against a blade or abrasive material.
Pencils do not use energy in the same way that electronic devices do. Pencils are simply tools for writing or drawing, and they utilize the manual energy of a person's hand to create marks on paper or other surfaces.
Conrad Gessner, a Swiss naturalist and physician, is credited with inventing the lead for mechanical pencils in the 16th century. However, the "lead" in mechanical pencils is actually made of a mixture of graphite and clay, not actual lead.
Mechanical pencils, like the regular kind of pencils, use graphite.
Yes, there is no rules written that you can't use mechanical pencils for school. However, it's better to get number 2 HB pencils because it's easier to erase.

Yes, mechanical pencils are allowed on AP exams as long as they meet the College Board's guidelines for acceptable writing instruments.
they are mechanical pencils
Mechanical pencils are not allowed on the ACT because they can be easily manipulated to change answers, which could give an unfair advantage to test-takers. The ACT requires the use of traditional wooden pencils to ensure the integrity of the exam.
yes mechanical pencils are very distracting

Yes. All pencils use lead - not the element, but a graphite and clay mixture molded into a long narrow strip.
That question is false. Americans use bot. Actually most Americans prefer mechanical.

All people use mechanical energy.
