Understanding the Physics of it All

Students will be able to (SWBAT):
1. Explain who Galileo was
2. State the reasons as to whether or not heavier objects fall faster and harder than lighter objects
We have watched October Sky and have taken a deeper look at the history of rockets and their structure. It's now time to take a look at what causes all of the forces that launch a Rocket. In order to do that, we need to go WAY back.....back to over 2,300 years ago!

Humans have always attempted to understand the physical world.The Ancient Greeks, over 2,300 years ago, arrived at insights which continue to shape the way we understand things. But, it has been the discovery of physics in the last 400 years that has truly revolutionized the way we understand our physical universe. Perhaps the most remarkable thing about physics is that some of the greatest understandings have come from our test to undertsand the simplest and most common everyday events. Who would have believed that our understanding of the solar system, stars, galaxies, and much more would come out of an attempt to understand why things fall??? Within your groups take a moment to watch the video below.

Galileo Galilei - commonly known as Galileo, Astronomer
Galileo is considered to be the father of science. He correctly figured out the rate of acceleration in falling objects. Do you think heavier items reach the ground faster and harder than softer things? Take a bowling ball and a feather, for instance, which one will fall first? Which one will fall the hardest?

Take a look at this brief video on Galileo and his findings.

Although Galileo was a brilliant astronomer and mathematician, he still was unable to explain the force that caused objects to fall. What do you propose it could be? In the discussion board, post your response as to what you think or perceive the force to be. Once you have posted your response, respond to AT LEAST ONE other peers response.

Mathematics is a major analytical tool of physics. Although Galileo began the major thought processes as to why things fall, there are many more scientsits who contributed to the understanding of motion and force. One scientist, in particular, Sir Isaac Newton, is one gentleman who should be given recognition.arrow-next-right.jpg
