Linear, Circular and Verticle Motion!

Build A Straightaway Track

Straightaway tracks challenge us to make sure the track rails are running perfectly straight in linear motion. Make sure the rails are level with each other and parallel to each other. 

Build A Track with a U-Turn

In today's lesson we will build a track that carries a marble in circular motion around a U-turn. The tighter the radius of the turn, the higher the bank will nee to be to keep the marble on the track.

A Complete Circle

In this lesson we will build a track that launch a marble in trajectory motion off the end of the track into a container.  The record is 17.5 inches in flight.

Friction Loss

Friction causes object to slow down. The marble encounters "friction lost" when the track is not flat or the track rails are uneven with each other.

Circle Around

The marble stays on the track in circular motion because of the outside track rail is slightly highe

Raising the outside rail provides centripetal force, which is constantly push the marble towards the center of the center of the circle, keeping it on the track. 

A Parabolic Curve

As the marble takes flight in projectile motion, velocity and momentum compete against the downward gravitational force on the marble, causing it go in an arching parabolic 

curve path.
