Exam 2 tomorrow will consist of 13 questions. To help you with a final checklist review, below is a list of topics that I will pick from to create the exam. I will hit 13 out of the 16 listed for tomorrow's exam. I will roughly follow the sequencing listed (the exam should unfold naturally with how we have moved through the course).

For each topic, if you are prepared, you should have a clear idea of what the topic is referring to on reading it, to the point where you could quickly construct a sample problem to work and then be able to solve it from scratch. Therefore, if you encounter any topic on this list for which you do not have this sense, give it some extra review time.

- State and carefully play out the definition of average velocity or average acceleration to solve for some unknown.
- State and carefully play out the definition of velocity or acceleration. This entails first differentiating and then evaluating the result.
- State and carefully play out the integral relationships that connect v to delta x, or a to delta v to solve for an unknown. The integral maybe via a given function or via a graph.
- Solve a single object 1D kinematics problems for the special case of constant acceleration. This is a matter of stating the equation from our triplet of equations that you need and carefully interpreting the given information to define the known quantities so that you can correctly solve for the unknown.
- Solve a 1D kinematics problem for two objects in motion. Same approach as for one, but you are now doing a breakdown of each object separately and then carefully working in the the aspect that connects the two.
- Be prepared to think conceptually / visually about a described scenario that challenges you to think carefully about kinematic variables in 1D especially with regard to the difference between velocity and acceleration.
- Solve a 2D projectile motion problem. This is also the first place where you must be on the lookout for speed (magnitude of v) calculations that require you to square components, add them, then take the square root.
- A conceptual (usually focused on the directions of velocity and acceleration) or calculational problem on the kinematics of uniform circular motion. The quantites involved could include v, a, T, and R (don't worry about omega yet).
- Work out an abstract treatment of N2L to solve for an unknown (either the acceleration or one of the forces, their components or maybe magnitude calculated from the components). Forces will be given explicity as F1, F2, ...., meaning this is focused on the structure of N2L and not yet on specific physical forces.
- Elevator problems give us a nice intro to physical forces and N2L. They are 1D, but they do require that we carefully think about now the description fixes the direction of acceleration and then how we systematically employ FBDs, choose a coordinate system, ...
- A single object 2D N2L problem and all that we systematically do to solve them. Here we use a limited aresenal of physical forces: weight mg, tension FT, normal force FN, and applied forces Fapp. FN in particular often doesn't work out to just be mg.
- A single object 2D N2L problem that additionally includes kinetic or static friction.
- A N3L problem either conceptual PeeWee Herman against the Incredible Hulk problem or any of its variants, or possibly a calculational problem that involves using N3L with multiple blocks in contact.
- A multiple object N2L problem that requires multiple FBDs. Sometimes N3L is required (block up against one another), other times not (ojects connected by ropes). These problems challenge you to really think about what it means to isolate an object. Interestingly, we can still apply our 'choose x along a' rule even if this means different axes for different objects.
- Investigate a model of drag to calculate terminal speed or possibly to use ratios or creative math to compare two scenarios where only one feature is different between the two.
- Apply the kinematics of uniform circular motion to handle the dynamics of uniform circular motion in the context of a full N2L analysis.
