Kinematics - Galileo

• According to the
Aristotelian theory (top)
heavier bodies fall faster
(Fig. 1).
• But this leads to a
contradiction (we said
that already!): If we tie a
heavy and a light body,
the two will fall faster
(Fig. 2) or slower (Fig. 3)
than the heavier?
• Galileo solved the
problem, by showing
experimentally that all
bodies fall with the same
acceleration (bottom).
