Getting Pushy-Lab 7
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.
Questions:
Conclusion:
From the data that our group collected during the trials completed in this experiment, we have concluded that objects with larger mass create more friction because there is more weight against the normal force. Equally, an object with a smaller mass creates less friction causing it to not slow down as much and have a higher velocity for a longer period of time. For example, Nelson took more time to stop on the skateboard because his mass is less than that of Nikita’s. This is because Nelson caused less friction on the skateboard against the normal force, which was the library floor.
- 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.
