Sections 2.6 - 2.7
Applying the equations
Doing a sample problem is probably the best way to see how you would use the kinematics
equations. Let's say you're driving in your car, approaching a red light on Commonwealth
Avenue. A blac

Sections 2.8 - 3.4
Graphs
Drawing good pictures can be the secret to solving physics problems. It's amazing how much
information you can get from a diagram. We also usually need equations to find numerical
solutions. Graphs
Motion in two dimensions
Sections 3.5 - 3.7
Extending things from 1 dimension
In 1 dimension, we wrote down some general equations relating velocity to displacement, and
relating acceleration to the change in velocity. We also wrote down the four equation
Motion in one dimension
Sections 2.1 - 2.5
Motion in 1 dimension
We live in a 3-dimensional world, so why bother analyzing 1-dimensional situations? Basically,
because any translational (straight-line, as opposed to rotational) motion problem can be
separ

Sections 4.1 - 4.5
Force
We've introduced the concept of projectile motion, and talked about throwing a ball off a cliff,
analyzing the motion as it traveled through the air. But, how did the ball get its initial velocity in
