... we modify our definition of distance. We measure the distances differently depending on the position. For example, if the lifeguard runs twice as fast as he swims, one meter in the water will count for 2 meters on the beach. By using this way of measuring distance (in mathematics, we say that we use ...

... • In 1673, Christian Huygens was able to determine the following relationship between ac, v and R. • Changing velocity is acceleration. The acceleration of the object is directed toward the center of the circle, and is of constant magnitude a=v2/r, where r is the radius of the circle and v is the sp ...
