Materials

Ramp:Cardboard, Glue, Wood

Rubber Band CarsPopsicle Sticks, Wooden Dowel Rods, Metal Rods, StrawsMilk Bottle Caps, Glue, Duct Tape

2. Calculations1. Elastic Potential Energy- Rubber Band stretched to 30 cm = PE = .9614 J

2. Mechanical Energy - Max speed calculated of Rubber Band Car = 1.1 m/sec- .0228 J

3. Velocity needed to complete loop- Velocity = 2.1 meters / second- =MUST FASTER THAN THE RUBBER BAND CARS

2. Calculations continued

4. Mechanical Energy of Rubber Band Car- .2783 J- Most of the Energy was not transferred to the forward velocity

5. Mechanical Energy of Regular Car- 3.08 m/sec = Greater than the necessary speed to complete loop- .511 J of Mechanical Energy

3. Trials-Ramp

-Very flimsy-We attempted to support it with wooden blocks

-Rubber Band Cars-Sturdy-Worked well except for wheels-With correct adjustments they were able to pick up a velocity

3. Trials continued

-Launching Pad-More consistent velocity-Met velocity requirement-Completed loop easily

4.Error Analysis

1. Rubber Band Carsa. Loss of traction on wheelsb. Inconsistent application of force from rubber bandc. Material / Size of wheels

2. Rampa. Needed to be more rigidb. Cardboard connection points should have been smoothed out

3. Launching platforma. Inconsistent application of force
