Metacognition Problem Solving Question:
Can I establish upper and lower limits on the result of your
calculation?
Always attempt to estimate upper and lower limits on a variable in
order to evaluate whether it has been correctly calculated.
In real life there are no answer books. Determining
if a solution is right or wrong is up to you.
Relevance: Kinematics can be used to
analyze motions in everything from athletic activities to the motion of vehicles
.

acceleration
slope of x vs. t curve =

Solve constant acceleration problems in one
dimension. using the kinematic equations (
3x5
you must memorize these equations):
v_{f }= at + v_{o}
x = 1/2 at^{2} + v_{o}t +
x_{o}
Remember, the above 2 equations are
only good when acceleration is
CONSTANT !!!

Recognize that all objects fall at the same
rate of acceleration when they are in a uniform gravity field.

Can I still work the problems done in class, several hours
or days later?
Some amount of repetition on the exact same problems is necessary to lock in
learning. It is often better to thoroughly understand a single example of a
problem type than to work example after example understanding none of them
completely.
