Roller Coaster

We made roller coasters in class today to demonstrate Newtons Three Laws of Physics. Our roller coaster was built with paper towel tubes and tape. It had three hills, a roller coaster aspect, and used a marble as the cart. While building our roller coaster we had to factor in friction, force, acceleration, and velocity. we started the roller coaster with a tall tube so it would have more time to accelerate to a greater velocity. We also tried to minimize the upward movement of the marble because the friction would slow it down. We had the marble moving down a lot so it would be going fast enough to complete the hills. Our roller coaster worked well after we finished construction. We learned a lot and had fun building this project.

Deborah Gordon, age 54, pleaded guilty to stealing money from Middlesex County College. She was the treasurer of the school and admitted to writing about $6,300 to herself in checks. Investigations revealed she was cashing checks from union funds including one for about $4,000.
The investigation started when they found out there was problems with their finances. The County College Police Department started investigations then. Deborah Gorden also pleaded guilty to a separate theft charge, admitting she took $628.06 from the North Brunswick Township High School Soccer Parents Association. She was given 5 years of probation for these crimes.
