Circular Motion & Centripetal Force
受众: High School类别: Physics
简介
A ball on a string orbits in a circle. The velocity vector (tangent) and centripetal force vector (inward) are shown continuously updating. When the string breaks, the ball flies off tangentially, illustrating why centripetal force is required.

Circular Motion & Centripetal Force
Description
A ball on a string orbits in a circle. The velocity vector (tangent) and centripetal force vector (inward) are shown continuously updating. When the string breaks, the ball flies off tangentially, illustrating why centripetal force is required.
Phases
| # | Phase Name | Duration | Description |
|---|---|---|---|
| 1 | Setup | 1.5s | Circle path and center point appear |
| 2 | Orbital Motion | 4s | Ball orbits with velocity and force vectors |
| 3 | String Breaks | 2s | Ball flies off tangentially |
| 4 | Formula | 2s | Fc = mv²/r displayed |
