  2.1 MOTION IS RELATIVE  
    
        
        
        Relative Motion What does the phrase "motion is relative" mean? Find out in this 
        online tutorial from the Department of Physics at the University of 
        Illinois at Urbana-Champaign. Foucault's 
        Pendulum Most of the time, the relative motion of the earth does not affect 
        our perception of motion. However, in 1848, Leon Foucault discovered 
        that when a large pendulum swings, the earth appears to "move under it." 
        Learn more about Foucault's pendulum from Dr. Kruszelnicki's fact-filled 
        site.  2.2 SPEED

        Free Fall and the Acceleration of Gravity Free fall is defined as 
        "motion under the influence of gravitational force only." Find out more 
        about free fall in this interactive tutorial from
