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 ? Rotational Motion and the Law of Gravity This chapter deals with rotational kinematics ? the relationships between rotational position, velocity, acceleration and time. Rotational dynamics will be discussed in the next chapter. Dynamics deals with energy, momentum, and forces. Universal gravitation is also discussed in this chapter in part since satellite and planetary motion involves rotation. Angular displacement, velocity, and acceleration Angle (() can be defined in terms of radius (r) and arc length (s) on a circle as
