Answers Highlighted in Green Rita Borland May 12, 2010 Quick Demonstration • After the applet loads, deselect the VELOCITY, ACCELERATION, and FORCE vectors, and the VELOCITY X, and VELOCITY Y graphs. • Reduce the VELOCITY of the mass to 0.5 m/s and the MASS to 1.5 kg. • Answer the following question: 1. In what direction does the force of the mass point? a) Always to the left. b) Always to the right. c) Always to upward. d) Always to downward. e) Always away from the center of the circular path. f) Always toward the center of the circular path. • Select PAUSE, and then check FORCE. Note its direction. Select PLAY to show that the force continues to point toward the center while in motion. • Answer the following question: 2. In what direction does the velocity of the mass point? a) Always to the left. b) Always to the right. c) Always to upward. d) Always to downward. e) Always away from the center of the circular path. f) Always toward the center of the circular path. g) Always perpendicular to the force.

Unformatted text preview: • Select PAUSE, and then check VELOCITY. Note its direction and the direction of its components. • Select PLAY. Notice and understand why the components are changing in size, while the full vector is not. • Note that the full velocity vector remains perpendicular to the force vector. • Answer the following question: 3. In what direction does the acceleration of the mass point? a) Always away from the center of the circular path. b) Always toward the center of the circular path. c) Always perpendicular to the force. d) Always in the opposite direction of the force. • Select PAUSE, and then check ACCELERATION. Note that the red arrow is in the same direction as the force, toward the center. Select PLAY. • Deselect VELOCITY and ACCELERATION. • Answer the following question: 4. What would happen to the force if I increase the velocity? a) It will get larger. b) It will get smaller. c) It will not be affected....
