Three connected investigations
- 01Net Force and Newton's First LawCombine forces acting on an object and use Newton's first law to decide when motion changes and when it doesn't.Open
- 02Newton's Second Law: a = F/mCompute acceleration, force, or mass with F = ma, reason about how doubling force or mass changes acceleration, and separate mass from weight.Open
- 03Net Force, Friction, and Newton's Third LawApply net force and F = ma to a sled opposed by friction, then reason about Newton's third law action-reaction pairs acting on different objects.Open
What this path asks you to reason about
- Combine forces into a net force and predict when motion changes.
- Compute acceleration, force, or mass with a = F/m and reason proportionally.
- Apply net force and friction together and explain Newton's third-law pairs.
