Unit 2

Today in class we learned about Kinematics which is the study of motion and how all motion is relative.  In this picture the motorcycle is stationary and is relative to the beach and the ground.  Even though it is stationary it is actually moving very fast if we look at it relative to space.  We also learned about scalar quantity and vector quantity.  Scalar quality is the measurement that has magnitude or in simpler language muchness.  Scalar quality is the distance or speed.  Vector quantity is a value that has both direction and magnitude (muchness).  Vector quantity is displacement and velocity and is how far you are from your starting point.  The difference between Scalar and Vector is that one is just about muchness (speed) (Scalar) and one is about both muchness (speed) and direction (Vector).
