Again, these concepts we discussed in class, but I still do not get them. Can anyone explain why they are true? 1) Will the acceleration of a car be the same when the car travels around a sharp curve at a constant 60 km/hr as when it travels around a gentle curve at the same speed? Explain. 2) Which pulls harder gravitationally, the earth on the moon, or the moon on the Earth? Which accelerates more? 3) When will your apparent weight be greatest, as measured by a a scale in a moving elevator; when the elevators: (a) accel. downward (b) accel. upward (c) is in free fall (d) moves upward at a constant speed? In what case would you weight be the least? When would it bethe same as when you are on the ground? My instinct for question three is that it is least on the way down, b/c your force, pushing on the scale is less. And it is greatest on the way up, since your force of push is stronger. And I would say in free fall it is the same as ground state?
