Galileo Galilei lived in several small towns of Italy. His thoughts and experiments led to some general understandings about the way things move. Isaac Newton improved and organized those ideas into three “laws”. Albert Einstein added to Newton’s wisdom!

Day 3 (Tues Oct 20)

1. -First, we came up with a shorthand for some common forces: Fs (support force), Fg (force of gravity), Ft (force of tension), Fa (applied force), Ff (force of friction), Fa (applied force, like a push by a hand)
   

2. -Next, we drew force forces that apply on objects at rest (static), including:
   

3. -    1) A book on a table, 2) a hanging 100g mass, 3) a 3 kg pyramid on a 4 kg box, and 14 kg lawnmower being pushed at an angle of 35° from  horizontal.
