Objectives: (those in Times font are from the AP Board)
1. Students should understand the general relationships among position, velocity, and
acceleration for the motion of a particle along a straight line, so that:
a. Given a graph of one of the kinematic quantities, position, velocity, or
acceleration, as a function of time, they can recognize in what time intervals
the other two are positive, negative, or zero, and can identify or sketch a graph
of each as a function of time.
b. Given an expression for one of the kinematic quantities, position, velocity, or
acceleration, as a function of time, they can determine the other two as a
function of time, and find when these quantities are zero or achieve their
maximum and minimum values.
2. Students should understand the special case of motion with constant acceleration, so
they can:

Unit 2 Objectives
a. Write down expressions for velocity and position as functions of time, and
identify or sketch graphs of these quantities.
b. Use the equations,
v = v 0 + at
1
x = x 0 + v 0 t + at 2

2
v = v 0 + 2a(x − x 0 )
to solve problems involving one-dimensional motion with constant acceleration.
3. Students should know how to deal with situations in which acceleration is a specified
€time so they can write an appropriate differential equation
function of velocity and
and solve it for v(t) by separation of variables, incorporating correctly a given initial
value of v.
4. Specify the position and velocity of an object, recognizing the importance
of a frame of reference.
5. Identify typical speeds for running, walking, driving and other common
activities.
6. Distinguish scalar from vector quantities, giving examples of each.
7. Distinguish distance from displacement and speed from velocity.
8. Define and give examples of instantaneous speed and instantaneous
velocity, distinguishing them from average speed and average velocity.
9. Define acceleration and explain what is meant by a meter/second2.
10. Know the value for the acceleration due to gravity at the surface of the
Earth and use this value when solving falling body and projectile
problems.
11. Describe how the vector nature of acceleration is related to the
acceleration of freely falling objects.
