Purpose: the purpose of this lab was to see how long it takes for the skater to roll along the chosen distance with a specific force that we selected.
Materials: Skateboard, spring scaler, timer, and a video camera
Procedure: Step 1- Have your 3 people: Skater, Holder, puller Step 2- Decide on a distance (15 squares) Step 3- Decide on a force for this first set of trials Step 4- Have the skater sit down Step 5- Have the holder put one foot on the front of the skateboard Step 6- Have the puller start pulling, keeping the force constant until the skater finishes up the distance Step 7- Record the data Step 8- Switch people Step 9- Repeat this process with 3 different forces

Part B
Purpose: The purpose of this lab was to see how long it would take for the skater to stop after the puller stops pulling at a certain distance and see how much the skater travels to the stop.
Procedure: Step 1- Have your 3 people: Skater, Holder, Puller Step 2- Decide on a distance (7 squares) Step 3- Decide on a force for this first set of trials Step 4- Have the skater sit down Step 5- Have the holder put one foot on the front of the skateboard Step 6- Have the puller start pulling keeping the force constant until they reach the distance and stop pulling and see how far and how long it takes them to come to a complete stop. Step 7- Record Data. Step 8- Switch people. Step 9- Repeat this process with 3 different forces .

Conclusion: During this lab, we traveled a certain distance with a set force to compare speeds and distances between people in our group. We concluded that the larger the force, the faster the person will go and the distance will be greater after being let go. When the force was greater, the person on the skateboard would go farther from the point of being let go. Mass was another factor in this lab. When the mass of the person on the skateboard was greater, the skater would not travel as far.
