Down, Down and Away!

September 22, 2007

Hi there, Miles here.  Sir Isaac Miles, to be precise!  Get it?  Anyway, today we’re going to be talking about the one famous guy who discovered gravity: Sir Isaac Newton!  Here is a portrait:

 

Sir Isaac Newton was born on January 4, 1643.  Here’s a boost on gravity, his famous discovery.  First of all, you might want to know that gravity affects light objects and heavy objects the same.  Types of lighter objects, such as pieces of paper, go slower if there is a good amount of air resistence.  That’s because the air is like a cushion that is sort of holding the paper up.  Make sense or not?

Here is a picture of a gravity meter — remember a meter is about three feet.  This picture shows a girl dropping a ball.  It shows the meters per second that the ball is falling.  It gains ten meters per second that it is falling.

Here’s an extra boost of knowledge.  You’ll see a lot of these in my upcoming entries.   

Physics in Space

Why don’t the planets bump into each other?  Because every planet has its own gravitational pull that keeps it in exact order in the Solar System.  The gravitational pull comes from the sun.   The inner and outer planets are surrounded by an invisible force field of gravity.  But that’s the part I don’t know if it’s true — one of those space mysteries. 

It’s about time I should be leaving.  Oh, one last thing.  The apple on the head legend about Sir Isaac Newton?  Never happened.  See, sometimes fiction can give you facts.
