Free fall
Free fall under gravity (no air drag): v = gt and y = h₀ − ½gt².
Free fall under gravity; air resistance ignored.
Key formulas
v=gty=h_0-\tfrac12 gt^2
How to use
- Set drop height h₀ and g.
- Play the fall and watch the auto-reset after impact.
- Estimate impact time with √(2h₀/g).
Applications
- Free fall: Free fall under gravity; air resistance ignored.
- Classroom focus: watch height, speed, and impact time.
FAQ
Why do masses fall together?
In the ideal model g does not depend on mass.
What does MVP mean on this page?
An interactive sketch with formulas and parameters. Polished Ready labs are the full bench experience.
What does the “Free fall” lab practice?
Tune parameters and match readouts to the “Free fall” relations — useful for prep and demos.
Is force always along velocity?
No. Net force aligns with acceleration; velocity can point elsewhere.
