🛝 Slide — Conservation of Energy

Slide down and watch the physics! As the rider descends, potential energy converts to kinetic energy. Change the slide height and surface friction to see how these factors affect speed at the bottom.

🔬 What It Demonstrates

Conservation of mechanical energy: at the top the rider has maximum potential energy (mgh) and zero kinetic energy. At the bottom, all energy converts to kinetic energy (½mv²). Friction bleeds some to heat, reducing final speed.

🎮 How to Use

Adjust slide height and surface friction. Press go and watch the energy meter shift from potential (blue) to kinetic (yellow) to heat (red). Can you reach maximum speed at the bottom?

💡 Did You Know?

This same energy conversion governs hydroelectric dams (water's potential energy → electricity), ski jumps, and even the Big Bang — where the universe's gravitational potential energy converted to the kinetic energy of expansion.

⚙ Under the hood

Draw a straight, arc or wave-shaped slide, launch a ball down it and compare run times against friction.
