Chapter 2 Objectives:

When you have completed Chapter 2, you should be able to:

... recognize that a rate is a quantity divided by a time interval.
... distinguish between average speed and instantaneous speed.
... perform units conversions given appropriate conversion factors.
... calculate the average speed of an object (given displacement and time interval) and recognize appropriate speed units.
... distinguish between speed and velocity.
... discuss what is meant by the statement "motion is relative".
... tell when an object's velocity is changing.
... tell what acceleration is, and recognize when an acceleration occurs.
... recognize that acceleration is not a relative quantity.
... distinguish between velocity and acceleration.
... calculate the acceleration of an object (given change in velocity and time interval) and recognize appropriate acceleration units.
... solve numerical problems involving objects having constant velocity.
... solve numerical problems involving objects having constant acceleration.
... state the acceleration of an object in free fall near the earth's surface in metric and "customary" units.
... recognize that the acceleration of an object in free fall is constant.
... solve kinematics problems involving free fall.
... discuss the effect of air resistance on falling objects in terms of distance traveled and velocity.

Possible Preconceptions to Correct:

Do you believe that any of the following statements are true? They AREN'T! When you finish Chapter 2, you should understand that each of these statements is FALSE, and WHY.

WRONG: It is possible to determine the "true" velocity of an object.
WRONG: It is possible to detect your "true" velocity.
WRONG: Speed and velocity are the same thing.
WRONG: Acceleration is the rate that speed changes.
WRONG: Acceleration is change in velocity.
WRONG: You can only accelerate by speeding up.
WRONG: Acceleration and deceleration are different things.
WRONG: If your velocity is zero, your acceleration must be zero, too.
