Unformatted text preview: Worksheet for Interactive Lab3 : Circular Motion Name _Rita Borland Physics 216 Grade 37/42 Date May 12, 2010__ Circular motion is one of the fundamental building blocks for understanding the physical world because it is so common. This interactive lets you examine the basic ideas of kinematics and forces for objects moving in circular motion. 1. (6 points) Use the controls under Show Vectors to draw arrows for several different quantities. The velocity vector is drawn in a special way: a big, bold arrow showing its direction and magnitude, plus smaller arrows for its horizontal and vertical components. How are the directions of the acceleration and force vectors related? They both point in the same direction. What about the directions of the velocity and force vectors? They are not related. The force points towards the center of the circular path and the velocity is pointing in the direction of the motion of the ball. And how are they influenced by the increase in mass and velocity slide bars? Both grow larger in size and speed. Excellent work! +6 of 6 points DH 2. (6 points) The large slider on the left changes the angle at which you view the spinning system. Try watching the motion from above (the default) and from the spinning system....
