Number the procedural steps in order from which was conducted in the experiment.
1. Place a dot where the front wheels stopped Measure the distance from the starting line to the dot.
2. Place the front wheels on the starting line. Release the car.
3. Make a starting line. Place the blocks onto the three vehicles in their appropriate places.
4.Take vehicle 1 and wind the rubber band 10 times around the rear axle.

A detailed plan for building an object
blue print
The amount of material in an object
mass
The horse you are riding stops quickly and you continue to move forward.
Law #1
What are two ways you can get an object to move slower or a short distance.
Add more mass, use less force, increase friction, or decrease potential energy
What are two ways you can get an object to go faster or farther?
decrease mass, decrease friction, increase force, increase potential energy
A design that reduced air resistance
aerodynamic
The resistance that is produced when two objects are rubbed together
friction
You run into your friend while in-line skating, and both of you fall in opposite directions.
Law #3
What effect should air resistance have on an object's distance and speed?
A. The object will go slower and a shorter distance
B. The object will go faster and a longer distance
C. There will be no change in speed or distance
A. The object will go slower and a shorter distance
Continue: Number the procedural steps in order from which was conducted in the experiment.
5. Repeat the procedure 4 more times so there is a total of 5 trials for vehicle 1
6. Repeat the process with vehicle two and three.
7. Record measurement onto data sheet.

The force that pulls objects toward the center of the earth
gravity
A force that puts air on an object and slows it down
air resistance
