Worksheet E: 2D motion. 1-I . A particle moves along the trajectory shown below at constant speed in the clockwise direction. a. On the figure, draw vectors to represent the velocity of the particle at points 1 and 3. Draw them big! Copy these vectors in the top space at right (labeled “1-3”) and label them 1 v G and 3 v G . b. Draw the vector change in velocity v G and the vector average acceleration of the particle between points 1 and 3. c. Repeat steps a and b for points 1 and 2 using the space labeled “1-2”. d. Consider the angle between 1 v G and v G in each case. As the points considered get closer together, this angle approaches a certain limiting value. The limiting value is: > 90° = 90° <90° e. Generalize: What is the relation between the direction of the acceleration and direction of the velocity for an object that is moving in a curved trajectory at constant speed? They are perpendicular to each other.
