Defying Gravity In physics, a force is that which can cause an object with mass to change its velocity. In this picture the subject puts a downward force on the skimboard in order to make it pop out of the water and spin. Gravitation is a natural phenomenon that gives weight to objects. He is defying gravity by making this board come out of the water and spin.
