Kinetic friction happens when there is kinetic energy and it is coming into contact with another source. ex: a ball rolling.
When an element has a low specific heat, this means that it requires less energy to increase the temperature of this element. Specific heat is measure in Joules/GramDegreeCelcius because it measures the amount of joules required to raise one gram of the element by one degree Celcius.
Pitch is way to relate a sound to its frequency. High frequencies have high pitches (think of a flute), and low frequencies have low pitches (think of a bass). <span>
