... hand in a circular motion and make the object spin. 5) Keep the object spinning at a constant force or speed. 6) Let go of the string and observe what happens. Procedure B: 1) Do steps 1 - 5 in procedure A. 2) As the object comes around, place your finger half way of the radius. 3) Let the object spin around your finger. 4) Observe if the speed, after you put your finger, is the same, faster or slower than the speed when you were just spinning the object without you r. (no finger) 5) Record the Data. Data/ Analysis The object flew off forward after the spinning. The object spun faster when the radius of the circle was smaller.

Whenever the object goes forward it is ...
