You would have the most quantity of gold if it weighed 1 N on the
1) Moon.
2) Earth.
3) planet Jupiter.
4) would be the same on each.
This is because
5) on the Moon a greater mass of gold is required for the gravitational force to equal 1 N.
6) weight and mass are directly proportional to each other.
7) gravitational force per mass is greatest on the most massive planet.
Question 2
A baseball is thrown straight upward. At the very top of its trajectory its instantaneous velocity is zero and its acceleration is
1) zero.
2) 10 m/s2.
3) between zero and 10 m/s2.
4) none of these.
We can better understand this by noting that when it is at its highest point
5) there momentarily is no motion.
6) its rate of change of motion is still 10 m/s2.
7) although its velocity is not changing, its direction is.
