I have trouble perceiving torques. We can feel the linear force because when someone pushes us we tend to fall into that direction and then we yell at that person :). However I wanted to know if I were to feel a torque how would that compare? So far my perception of a torque is just numbers and symbols.

Note: Coal and oil are non-renewable re-
sources.
A friend says the energy of oil and coal is actually a form of solar energy. Is your friend correct, or mistaken?
1. Mistaken; the energy is actually nuclear.
2. Mistaken; the energy is actually geothermal.
3. Correct; these materials are the result of photosynthesis, a physical-chemical process that incorporates the sun's radiant energy into plant tissue
