K1: Define and apply the concepts of
position, distance, and displacement.
Situation 1: You go to your f riends
house.

K2: Define and apply the concepts of average
and instantaneous speed and velocity.
You drive 4.00 mi at 30.0 mi/h and
then another 4.00 mi 50.0 mi/h. Is
your average speed f or the 8.00 mi
trip greater than, less than, or equal
to 40.0 mi/h?

K2: Define and apply the concepts of average
and instantaneous speed and velocity.
An athlete sprints 50.0 m in 8.00 s,
stops, and then walks slowly back to
the starting line in 40.0 s. If the sprint
direction is taken to be positive, what
are the average sprinting velocity,
average walking velocity, and average
velocity f or the trip?

Is the instantaneous velocity at
t=0.500s greater than, less than, or

Relation to Calculus
Instantaneous velocity is determined with the
derivative of position.
Average velocity is obtained with the « old »
method of xs and ys.
