kinetic energy depends on.......................
500
because of conduction no matter is created nor destroyed
in a cup of hot coco why does the spoon get hot. Is any matter created or destroyed.
500
potential= energy due to its position kinetic= energy due to its motion
What is the difference between potential and kinetic energy
