Final Velocity of a Block on a Fixed Wedge Calculator

Final Velocity of a Block on a Fixed Wedge Calculator

When a block slides down a frictionless, fixed wedge, the gravitational potential energy lost from a vertical height \( h \) is completely converted into kinetic energy. This gives:
\[ v = \sqrt{2gh} \]

* Enter the vertical drop (h in m) and gravitational acceleration (g in m/s²) in SI units.

Step 1: Enter Parameters

Example: 5 m

Example: 9.81 m/s²

Formula: \( v = \sqrt{2gh} \)


Practical Example:
For a vertical drop of 5 m and \( g = 9.81 \) m/s², the final velocity is:
\[ v = \sqrt{2 \times 9.81 \times 5} \approx \sqrt{98.1} \approx 9.90\, \text{m/s} \]
