Purpose: The purpose of this lab was to find out how the mass of someone relates to their velocity when pulled at a certain force.
Procedure: There are three people participating in this experiment each time that it is performed: the skater, the puller, and the holder.

Purpose: The purpose of this lab was to find out how the mass of someone relates to their velocity when pulled at a certain force.
Procedure: There are three people participating in this experiment each time that it is performed: the skater, the puller, and the holder.
- The skater sits on the skateboard.
- The holder, holds the board so that it is at a constant force when released.
- Mark off varying distances on the ground.
- Zero the spring scale while it is held by the skater at 0m mark.
- Determine the force to be applied to the skater.
- While the holder is holding the skater still, the puller should apply the determined force.
The person with bigger mass stops earlier, due to an increase in friction. The person with a smaller mass, will stop later because there is less friction in the wheels.
Questions:
Questions:
- An increased force would will increase the acceleration of the skater.
- As the mass of the skater increases, the acceleration decreases.
- An increased distance would increase the acceleration of the skater.
- When the force is constant, an increased distance would increase the final velocity.
- If a force is applied to the skater and there is no change in motion, there must be an opposing force countering the other force, causing the net force to be zero.
- Our observations reject the notion that a constant force is required to produce a constant speed.
As observed in the experiments conducted: on Earth, the more mass an item has, the easier for it to slow down and stop when moving. This is due to the fact that with ore mass, the gravity will pull on in so that a massive item will have more weight than that of a less massive object. Objects weighing more will have more friction act upon in it in motion and therefore if not supplied with applied force constantly (may not be in constant amounts) will stop; as was the case in the experiments, in which only one burst of applied force was given.
