Law of conservation of energy

The aim of the experiment is check the energy conversion law. You need speedometer, metal bar as load, strings and ruler. Metal bar hanging on string has potential energy. If you release the bar, its gravitational potential energy will convert into kinetic energy of moving bar. With the speedometer you can measure speed of the bar. You can now easily calculate kinetic energy. Compare the potential enery and kinetic energy of the bar and analyse the result.

Enter the mass of metal bar : $ g $

Final height
$$ h_2 \quad (cm) $$
Initial height
$$ h_1 \quad (cm) $$
Speed at final position
$$ \upsilon \quad (m/sec) $$
