An archer pulls back a bowstring, bending the limbs of the bow, and then shoots an arrow vertically upwards into the air.
Which form of energy is stored in the bow because its limbs are bent?
Which form of energy of the arrow increases as it is accelerated immediately after being released?
Which form of energy of the arrow increases as it rises higher into the air?
Which two quantities need to be known in order to calculate the work done against gravity in lifting the arrow from its launch point to its maximum height?
