Blog Post #4

Hey, so today's blog post is still on kinematics.  So for those of you who have not gotten what kinematics is yet, its the study of motion.  Today, I will talk to you about acceleration.  Acceleration is the change of velocity per unit of time.  This means simply that the velocity changes when time increases.  The video I posted is of gravity or ag.  This is basically the acceleration of gravity.  Gravity accelerates at a rate of 9.8 m/(s^2).  The ball is used as a representation of gravity in which the ball accelerates as it bounces.  When it bounces, the gravity weighs down on it till it hits the ground and bounces till it stops.  Therefore, it demonstrates acceleration.
