Kinematics

      Kinematics is the branch of mechanics associated with motion.  All motion is relative.  Two cars going 40mph are moving, relative to the road.  However, the two cars are not moving relative to each other.  Below is an example of motion.


    The fan above is completely still.  It is not moving relative to the room.  However, when I turn the fan on, 


suddenly, the fan blades, relative to the room, is in rapid motion.  The neat thing about motion is that it is always relative.  While the fan blades are spinning around in circles, they are not moving relative to each other.  Since they are moving at the same speed, relative to each other, there is no motion involved.

    Nice post! If you are laying in your bed are you moving relative to the spinning fan blades?

    I like how you gave the example at the top about the cars, and then you explained your example of your picture with the fan.

    This is a creative way of explaining kinematics. If the fan is off and were moving around the room, are we moving relative to the fan?

    The fan is a good way to explain relative motion! It was good how you used other examples to help your explanation. I like your pictures and how you can see the change!
