Name ____________________ Date ___________?Mr. Carcich Physics 2D Motion Short Answers 1) Distinguish between rotation and revolution. Using the earth, provide an example of each. 2) Distinguish between rotational and tangential speed. What is their relationship? 3) If you are on the center of a merry-go-round, and you walk toward the outer edge, how does your rotational speed change? Your tangential speed? 4) When you whirl a can at the end of a string in a circular path, what is the direction of the force that acts on the can? 5) Does an object undergoing uniform circular motion accelerate? Why? 6) When a car makes a turn, do seat belts provide you with a centripetal force or centrifugal force?

1 Position(x, y or z) Displacement (?x, ?y or ?z) Change in position. Depends only on initial and final positions, not on path. Includes direction. ?x = ?vdt Velocity (v) Displacement per unit time Average velocity vave = ?x/?t Instantaneous velocity v = dx/dt ?v = ?adt Acceleration (a) A change in velocity: speeding up, slowing down, or turning. Average acceleration aave = ?v/?t Instantaneous acceleration a = dv/dt Problem: Acceleration (B-1993) 1. In which of the following situations would an object be accelerated? I. It moves in a straight line at constant speed. II. It moves with uniform circular motion. III. It travels as a projectile in a gravitational field with negligible air resistance. (A) I only (B) III only (C) I and II only

Chapter 7 Problems 1, 2, 3 = straightforward, intermediate, challenging = full solution available in Student Solutions Manual/Study Guide = co ached solution with hints available at www.cp7e.com = biomedical application Section 7.1 Angular Speed and Angular Acceleration 1. The tires on a new compact car have a diameter of 2.0 ft and are warranted for 60 000 miles. (a) Determine the angle (in radians) through which one of these tires will rotate during the warranty period. (b) How many revolutions of the tire are equivalent to your answer in (a)? 2. A wheel has a radius of 4.1 m. How far (path length) does a point on the circumference travel if the wheel is rotated through angles of 30?, 30 rad, and 30 rev, respectively?
