 Chapter Objectives: Explain the idea that motion is relative. Define speed and distinguish between instantaneous speed and average speed. Distinguish between speed and velocity, and describe how to tell whether a velocity is changing. Define acceleration and give examples of its units. Describe the motion of an object in free fall. Describe the motion of an object thrown straight up and allowed to fall until it hits the ground. Determine the speed and the distance fallen at any time after an object is dropped from rest, when air resistance is negligible. Explain how graphs can be used to describe relationships among time, distance, and speed. Describe how air resistance affects the motion of falling objects. Explain why acceleration is a rate of a rate. back to top Chapter Terms: speed velocity acceleration free fall back to top Chapter Formulas: Speed = distance/time Average Speed = total distance covered/time interval Acceleration = change of velocity/time interval Acceleration (along a straight line) = change in speed/time interval Velocity acquired in free fall from rest: v = gt Distance fallen in free fall from rest: v = ½ gt2 Chapter Outline Framework: Motion is Relative Instantaneous Speed Average Speed Velocity Acceleration Accelerationon Galileo's Inclined Planes Free Fall How Fast How Far How Quickly How Fast Changes Hang Time back to top The Formulator
