II. If you ever watched "Sherman and Mr. Peabody" you became aquainted with Galileo Galilei. He invented some pretty amazing stuff that turned out to work once technology caught up with his mind. But that's not all he did.
In Classroom you will find a brief biography about Galileo. Use the biography to answer the provided questions/prompts. (Due Friday, 8am.)
III. There's a famous "scientific urban legend" that Galileo studied gravity by dropping cannon balls out of the Leaning Tower of Pisa. While probably not true, the idea does set the stage for us to do a similar experiment.
Gravity - when an object is dropped it undergoes free fall. This thing called gravity is a force that accelerates that object faster and faster and faster. Today we will try to determine what that acceleration is. In other words, WHAT IS THE ACCELERATION DUE TO GRAVITY???
To help us we need to know that acceleration is a calculation, and therefore has a formula.
a = 2*d / t^2
Let's decode what all of this means?
What measurements do we need to take?
Once we have them how do we do the calculation?
Example) A car at a stop sign hits the gas and after 10s it has gone 75m. What was its acceleration?
I. Before we go outside and test Galileo's idea, we need to create a Sheet that will allow us to record data and calculate the acceleration of the ball we drop.
Also, we need to write our Title and Purpose.
