Roller Coaster Physics

Roller Coaster Physics.

The principle that underlies the working of a roller coaster is simple. As you ascent to the top, your potential energy builds up. ( i.e the higher you go, longer the distance that the force of gravity can act upon)

This built up Potential energy gets released as kinetic energy downhill. ( Kinetic energy is the energy of motion- linear and rotational). 

Now what Roller Coaster Engineers do is abuse this principle to engineering perfection.

Waterball Ping Pong

"Astronaut Scott Kelly has spent more time in space than any other American. He has also played solo ping pong with a ball of water and two hydrophobic paddles."

Magnets and Marbles

Here we have an incredible marble track which incorporate different sized magnets used to repel and attract in order to further the marble track.

This is great for discussions/examples of magnets and force.
