Forces That Accelerate
This week, we learned more about Newton's Laws of motion.  More specifically, acceleration and Newton's second law.  Newton's second law states, 'the acceleration of an object is directly proportional to a net force on an object and the acceleration of an object is inversely proportional to the object's mass.  From this law, we learn that acceleration is directly proportional to the Fnet (sum of all forces), and that acceleration goes down as the mass of an object goes up (vice versa).  This is represented by the equation a=Fnet/mass.
Fnet can be found by the equation Fnet=m•a.  (m = mass, a = acceleration)

A force that accelerates is a skater.  While cruising around my neighborhood, I noticed that I was accelerating with every push I took. I realized that as i pushed on the ground, the ground pushed me back and accelerated me forward.


And Fight Club was a very good movie.
