What is Gravity?
This video relates the three main ideas about gravity. They are all right. This video starts
out with the most elementary ideas (ideas one and two) and then ends with Newton’s
Law of Universal Gravitation – which states that all objects are attracted to all other
objects.
Misconceptions about Falling objects.
This video addresses why objects of similar size, but not mass, will hit the ground at the
same time. Remember, that although they do hit the ground at the same time, the heavier object
(the one with more mass) has a greater force than the lighter object. They hit the ground at the
same time because of inertia. The heavier object has more inertia (resistance to change in
motion) and so it take more force to accelerate that object at the same rate as the lighter object.
This results in both objects hitting the ground at the same time.
