Term

Landing Normal-Velocity Component

The component of velocity perpendicular to the landing surface, used in an educational model of jump landings and absorption.

HOW TO DO IT

Landing Normal-Velocity Component

The landing-normal component is the part of velocity directed perpendicular to the local contact surface. It helps explain why flight height alone cannot describe the landing event.

Preparation and setting

Basic vector understanding and an identified landing surface; conceptual use only.

How to understand / apply it

  1. Identify incoming velocity direction.
  2. Identify the surface normal.
  3. Separate normal and tangential components.
  4. Explain how changing geometry alters that decomposition.
  5. State the assumptions before interpreting a model.

How to learn / practise

Use diagrams or numerical examples in a later tool if needed. No riding experiment is required to understand this concept.

Errors and corrections

Treating the model as a personal safe-height calculator ignores body, snow and contact complexity. Estimating speed from appearance is not measurement.

Observable checks

The learner distinguishes total speed from its normal component and states model limits.

editorial review notes

The PICUP model also explores launch speed, landing slope and model limits; it explains why height alone cannot characterize a landing. No model-derived safe drop height, minimum speed or injury threshold is approved; force estimates are not a personal clearance calculator.
