Acceleration and Velocity
This week in physics, we learned more about Kinematics and motion.  We touched more upon acceleration and velocity.   Velocity, measured in meters per seconds squared (m/s^2), is found by taking the slope of a position vs. time graph.  Acceleration, measured in meters per second (m/s), is found by taking the slope of a velocity vs. time graph.  The picture below represents both acceleration and velocity because as the skater pushes off the ground he increases his acceleration.  When he coasts down a hill or maintains a certain speed while skating the streets, his velocity is constant.  When doing speed checks (as shown below) a skater is able to manipulate his velocity.  Physics never fails to explain everyday occurrences.
