# Lab Skate Park - Energy Conservation Laws

## Question

LAB SKATE PARK
The objective is to observe energy conservation laws.
PROCEDURE A
Start from 6 meters height and decrease the height by 1 meters each time. Observe velocity at the bottom. And calculate it using energy conservation law. Find % err

Height (m)    Velocity observed    Velocity measured    %err

E = ½ m v² + mgh             For this part Ef = Ei
PROCEDURE B
Do the experiment with friction. Start from 6 meters height and decrease the height by 1 meters each time. Observe velocity at the bottom. Calculate Wnc.
Height (m)       Velocity observed    Ei    Ef    Wnc

E = ½ m v² + mgh       For this part Ef – Ei = Wnc
