How to use the rolling down a ramp calculator
Find the speed of a rolling object at the bottom of a ramp. Enter ramp height, shape in the fields above; the speed at bottom, speed if sliding (no friction) are computed instantly and plotted on the chart so you can see how the answer changes.
Formula
Variables
- h — Ramp height (m)
- k — Shape (—)
Worked example
With ramp height = 1 m, shape = Solid sphere, the calculator gives speed at bottom ≈ 3.742927 m/s; speed if sliding (no friction) ≈ 4.428691 m/s.
Frequently asked questions
What is the formula for the rolling down a ramp calculation?
Speed at bottom (m/s) = √(2 × GRAV × h / (1+k)). Speed if sliding (no friction) (m/s) = √(2 × GRAV × h). Here h is ramp height (m), k is shape (—).
What inputs do I need for the rolling down a ramp calculator?
You need ramp height in m, shape in —. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use this calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
