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.

Learning targets

Differentiate scalar and vector quantities with examples.
Use $\pu{m.s-1}$ and $\pu{m.s-2}$

Quantity	Definition	Formula
Speed (scalar)	Rate of change of distance.	$v = \frac{d}{t}$
Velocity (vector)	Rate of change of displacement.	Includes direction.
Acceleration	Rate of change of velocity.	$a = \frac{\Delta v}{\Delta t}$
