We have studied four different laws authored by Sir Isaac Newton. For each of the following, indicate which law is best for the task described.
(a) Calculating the force exerted on a satellite by the Earth.
(b) Showing the mathematical relationship between mass and weight.
(c) Explaining the direction that a rubber stopper takes after the string that was keeping it moving in a circle overhead is cut.
(d) Explaining why a gun recoils when it is fired.
(e) Explaining why a wing on an airplane is lifted upward as it moves through the air.
