Teachers, save “TEKS Reflection/Force, Motion, and Energy” to assign it to your class.

Using the information provided from the 9 weeks assessments. Use and to record progress. Common note mistakes are: • Incorrectly solving for unknown variables in the mathematical formulas • Mistakenly combining forces, including friction, that are in opposite directions rather than subtracting • Misidentifying results of unbalanced forces • The misunderstanding that speed has no direction and velocity has direction • Thinking that acceleration is only an increase in speed • Misinterpreting constant speed on a speed/time graph as being at rest • Misinterpreting units for speed, velocity, and acceleration • Not recognizing constant speed as the result of balanced forces and no acceleration • Not identifying gravity as a force that moves the Earth’s tectonic plates • Confusing speed and acceleration • Not recognizing that acceleration includes the slowing down of an object and a change in direction
