Gravity in Space

Astronauts experience the sense of weightlessness in space because they are orbiting planets which is like constantly falling through space. Imagine being in a elevator in the twin towers and somebody cut the cables, for a small period of time you would feel weightless because you are falling at a faster acceleration than gravity. In space there is gravity its just that when you are orbiting a planet your acceleration is faster than that of gravity which is trying to pull you down, which gives the feeling of weightlessness. Here is a video to show astronauts feeling weightlessness. http://www.youtube.com/watch?v=coX1u2_KBsQ

what is acceleration?

Acceleration is the measure of an object that speeds up or slows down. In other words it measures the rate of increase and decrease of speed. The formula for calculating the acceleration of an object is a=v/t and F=ma. The acceleration is when there is a change in the velocity there is a change in the acceleration. When you have an increase of velocity the acceleration changes and like wise for a decrease in velocity.

The Distance from Parish to my House

D                          E                    S                        A
X=21.5 mi          V=X/T           V=21.5/0.5       V= 43mph
T=30min
V=?
From my house in Frisco it takes 30 minutes to get to parish without traffic. This car ride is 21.5 miles.  find the average speed?  The formula for this equation is V=X/T, V being the velocity, X being the distance traveled and T being the time. From my house to Parish we drive an average of 43mph.

Pendulum Lab

Pendulum Lab

When a Pendulum is swinging, the length of this pendulum has a certain time attributed to each swing. When the length of a pendulum is shortened,  the time it takes to complete a full swing is shortened.

When the length is increased,  the time it takes to complete a full swing of the pendulum increases. 

I began the experiment of the pendulum with a length of 225cm and timed it with a stopwatch.  I progressively shortened the pendulum's length and timed it at each length to test the theory that the swing time would shorten as the pendulum shortened.  I swung the pendulum 7 times at 7different lengths and timed each one.

The pendulum's starting length of 225cm gave the pendulum a full swing of 3.034 seconds.
I then shortened the pendulum to 202cm and the time it took to make a full swing was 2.982 seconds, which was 0.052 seconds shorter. For each following swing as the the pendulum was shortened the full swing time was shortened.

The length of the pendulum directly influences the time in which it takes for the pendulum to make a full swing.
