There is no air resistance on the moon, so when Neil Armstrong dropped a
hammer all of the potential energy turned into kinetic energy. If Neil was 12
feet tall instead of 6 feet, would the hammer be moving faster or slower
just before hitting the ground? Why?

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.
