- Getting the hang of identifying formulas that'll help you solve the problem at hand. - Successfully identified the correct units for values to substitute into formulas. - Got the hang of reading graphs of linear motion.

Formulas} - It can be helpful to think of formulas as ... -- Recipe analogy: A recipe showing you how to create the variable you want to find using the ingredients you already have. Each formula uses a particular set of ingredients and creates only the variables it has. -- Chemistry analogy: Chemical ingredients that react with each other to produce new chemical ingredients. For example, in F = ma, m and a react to produce F. Also, F and m react to produce a, a = F/m. -- Puzzle analogy: Pieces of a puzzle, where one piece is missing. The pieces you have guide you to find the missing piece and thus complete the puzzle. -- Team analogy: A team where one member is missing. The team members work together to find the missing member. - How do you then identify the ingredients, puzzle pieces, or team members you know? You extract them from the info given in the question. Once you know what you're given and what you want to find, you can use the analogies to help you find a formula that finds what you want to find. - How do you identify what you know from graphs? The axes will tell you two variables. You can then use the analogies to obtain other variables. - A problem may require you to use multiple formulas to get to the variable you're asked to find. It's like first building the wheel before using that wheel to build the car. It's also like you hunting for treasure with a compass, but the compass only points to a map that guides you to the treasure. You find the map (use a formula to find an intermediate variable), then use the map (the intermediate variable) to find the treasure (the specific variable you're asked to find). General - Keep practicing questions where you're presented with a graph and asked to analyse it or find a variable(s) from it. - Revise the idea of a spring constant. Force applied to extend/compress a spring (F) = Spring constant (k) x Extension (x). The spring constant is a measure the stiffness of the spring, i.e., of how rapidly the force needed to extend/compress a spring further grows as you extend/compress the spring. The greater the spring constant, the greater the stiffness.

- Successfully used physics to calculate stopping distance for a car. - Successfully calculated the amount of energy dissipated as heat by calculating a difference in kinetic energy. You thereby leveraged the fact that energy is converted from one form to another. - Getting the hang of net force. - Got the hang of the law of conversation of momentum. - Successfully analysed the motion physics of a bouncing ball.

- Be careful of whether a question asks for "acceleration" or "deceleration". Acceleration has a direction, so you'd write the direction. Deceleration means "slowing down", so a positive number for deceleration means slowing down. I.e., you wouldn't write the negative sign in this case. - Keep practicing solving questions involving multiple individual forces asking you to calculate the net force, like Q7.

- Successfully calculated the determinant of a matrix. - Got the hang of linearisation functions. - Got the hang of transforming the x-axis (or y-axis) from a linear scale to a logarithm scale, like in Q17. - Got the hang of how to correctly fit a least squares regression line using your CAS calculator. On your CAS calculator, you press Menu, 4 (Analyse), 6 (Regression), then 2 or 1. - Successfully applied linearisation functions to data using your CAS calculator. - Got the hang of transition matrices and state matrices (Q2 on p. 15).

- Remember that the matrix equation in Q1 has 4 separate equations. Equations in a matrix can be read element-by-element, as below, only if the matrices are added or subtracted. Multiplying matrices follows different rules, like in Q2 on p. 3. - When multiplying matrices, the order in which they're written matters, as explained for Q2. - Multiplying a matrix by a scalar (e.g., 2) merely multiplies each element of the matrix by that scalar, as explained for Q3 on p. 3.

- Remembered SOH-CAH-TOA, which is a way to remember which trigonometric ratios belong to which trigonometric function. - Getting the hang of deriving three-figure bearings from unit circle diagrams. - Getting the hang of calculating three-figure bearings from angles you've calculated using Trigonometry. - Getting the hang of using the sine rule.

- Keep practicing questions where you derive three-figure bearings. Remember that three-figure bearings start from north and go positive clockwise. - Remember that the angles you calculate using Trigonometry are usually not the three-figure bearings. You'd use those angles to calculate the bearings. - Keep practicing questions using the sine and cosine rules. Try looking for visual demos or videos about them as needed.
