Most students memorize F=ma and think they're done. That's not enough.
Here's the process that actually works:
Step 1 β Identify every object in the problem.
Step 2 β Draw a free body diagram for each one.
Step 3 β Choose a coordinate system and stick to it.
Step 4 β Write F=ma for each direction separately.
Skip any of these steps and your answer will be wrong, even if your math is perfect.
