3.4.1.6 Momentum
| Content | Opportunities for skills development |
|---|---|
Conservation of linear momentum. Principle applied quantitatively to problems in one dimension. Force as the rate of change of momentum, |
Impulse = change in momentum
, where is constant.
Significance of the area under a force–time graph.
Quantitative questions may be set on forces that vary with time. Impact forces are related to contact times (eg kicking a football, crumple zones, packaging).
Elastic and inelastic collisions; explosions.
Appreciation of momentum conservation issues in the context of ethical transport design.
MS 2.2, 2.3 Students can apply conservation of momentum and rate of change of momentum to a range of examples. |
