5/5 What did Galileo discover in his legendary experiment at the
Leaning Tower? Galileo found that, except for variations in air
resistance, all objects fall at the same acceleration (change in
velocity over time). This refuted thinking attributed to
Aristotle that said that heavier (more massive) objects would
fall faster. Specifically, Galileo found that objects with
different masses, when dropped side-by-side at the same time,
would both hit the ground at the same time. 11/11 Why do we say
that force is a vector quantity? Vectors have both a magnitude
(strength) and direction. Force has both. Applying a force in a
particular direction causes changes in motion (accelerations)
only in that direction. The amount of change in motion scales as
the magnitude of the force. 18/18 When you stand at rest on a
bathroom scale, how does your weight compare with the support
force by the scale. Your weight, which is the force of gravity
pulling you towards the center of the Earth, is equal in
magnitude to the support for
