Ideas about Weight and Falling Speed

Aristotle's interest in the structure of living things was encouraged by his father. That intrest helped Aristotle develop strong observation skills. He went on to apply his observation skills to a wide range of topics. 
Those topics included politics,nature,ethics,astronomy,and physics.

In time, Many of Aristotle's teachings in physics would be proved wrong. His errors included thinging that

• All motion on Earth occurs in a strainght line(called linear motion)
• an object continues in motion only as long as someting acts on it to keep it moving.
• a heavy object falls faster than a light object.
• Earth is at the center of the Universe.

Remember that these beliefs were based on observation and thought.
