Projectile on an Incline Calculator
(Downward Launch)
Calculate the parameters of a projectile launched from an elevated point above an inclined plane with a downward initial direction.
The projectile is launched with an initial velocity \( v_0 \) at an angle \( \theta \) relative to the horizontal, the incline is at an angle \( \beta \), and the launch point is \( h \) meters above the plane.
* Ensure that \( v_0\bigl(\sin\theta-\cos\theta\,\tan\beta\bigr) < 0 \) so that the projectile moves downward relative to the incline.
Step 1: Enter Parameters
Example: 20 m/s
Angle relative to horizontal (should be small for downward launch)
Angle of the incline relative to horizontal
Height of the launch point above the plane
Default: 9.81 m/s²
