Q: What does IP Combined Science Notes (Lower Sec, Year 1-2): 07) Forces, Motion & Simple Machines cover?
A: Resolve forces, calculate speed and acceleration, and evaluate moments plus mechanical advantage.
Physics of everyday motion hinges on clear diagrams and consistent units. Develop habits for vector addition, graph interpretation, and machine efficiency.
These notes align with MOE's Lower Secondary Science syllabus themes commonly taught in IP Sec 1–2, and act as a bridge into upper-secondary Physics, Chemistry, and Biology.
Status: MOE Lower Secondary Science syllabus (current release) checked 2025-11-30 - scope unchanged; remains the reference for these combined science notes.

| Read time | What to take away |
| 1 second | Forces explain changes in motion. |
| 10 seconds | Draw the forces first, find the resultant force, then decide whether the object stays still, moves at constant velocity, or accelerates. |
| 100 seconds | Example: a velocity-time graph gives acceleration from its gradient and displacement from the area under the graph. Do not mix those two readings. |
