2. LINEAR MOTION
2.1 Units
- Define the SI units of measurement 
- Use common metric prefixes
- Practice of unit conversion.
2.3 Speed
2.4 Velocity
2.5 Acceleration
2.6 Velocity and Acceleration
- Understand the difference between distance and
displacement and between speed and velocity.
- Distinguish between average speed and average velocity.
- Define acceleration.
- Interpret graphs of position versus time to determine the
velocity of an object.
- Determine from a graph of velocity versus time, the velocity
of an object at a given time and the time at which an object
has a specific velocity.
- Calculate the displacement of an object from the area under a
v-t curve.
2.7 Displacement, Time and Acceleration
2.8 Displacement, Velocity and Acceleration
- Use the kinematics equations to solve problems for an object
moving with a constant acceleration along a straight line.
2.9 Acceleration due to Gravity
- Recognize the meaning of the acceleration due to gravity.
- Determine the sign of the acceleration relative to the chosen
coordinate system.
2.10 Free Fall
- Use the motion equations to solve problems involving freely
falling objects.
