Worksheet for Interactive Lab3: Circular Motion Name _____________ Physics 216 Grade ___/42 Date ______ 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? Force has a magnitude and a direction, and it is a vector.…show more content…
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. Question 2 (3 points) 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. Question 3 (3 points) 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. Question 4 (3 points) 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. Question 5 (3 points) Angular velocity is not described by …? A) Revolutions per minute B) Meters per second C) Radians per minute D) Angular displacement Question 6 (3 points) An object is in uniform circular motion. Identify the correct statements. 1. Its acceleration is constant (acceleration is a vector quantity). 2. Its radial acceleration component is constant in magnitude. 3. Its
