Terminal Velocity Lab
Introduction:
This lab is an experiment in terminal velocity, the speed an object cannot surpass due to frictional forces.
To begin, it is important to note that the objects in this lab are not in a free-fall scenario. A free-fall scenario is a situation where an object is dropped in a frictionless environment, and the only force that is acting upon it is the force of gravity. In a free fall environment, terminal velocity would not occur, because no frictional forces would act on the object to stop it from continuing to accelerate. It this lab situation, the force of friction (air resistance) has an effect on the falling object.
The air resistance (force of friction) that causes terminal velocity is caused by a few things. The mass, the density of the air, and the surface area all have an impact on how much air resistance there is. In this lab, because the density of the air in the school is relatively constant and should not change during the experiment, we can ignore that value (it is constant). The surface are should not change either (the cupcake liners are stacked), so we can also ignore that value. We choose to measure the mass of the cupcake liners because that is the only factor in air resistance that will change throughout this experiment.
In conclusion, terminal velocity is caused by air resistance, which is caused by mass.
Purpose:
The purpose of this lab is to investigate the causes of terminal velocity, specifically the relationship between terminal velocity, mass, and air resistance.
Materials:
-20 “Giant Cupcake Liners” -3 timers -String -metre stick Procedure: See assignment sheet

Results: See assignment sheet for table of values Discussion: 1. Using your graphical analysis techniques, straighten out the graph of velocity vs. mass and determine the relationship between terminal velocity and mass. Write this relationship as a variation statement. ∴ v ∝ √m 2. Determine the constant of

    Our plan was to drop an object from a reasonable height and use a ticker tape timer to measure the amount of time and distance travelled between each time. The weight of the object used would have to be heavy enough that it would not be affected by air resistance. For example, you shouldn’t use a piece of paper because due to the surface area and weight of the paper, the fall would be slower which would affect further calculations. However, if you used a weight which was heavy enough, the effect of air resistance would be minimal. For our experiment, we would use several things which would help us gather data so that our calculations would be nearest to the true value of g (acceleration due to gravity). One object which we used was a pulley system. We put a string through the pulley and attached the weight to the string. This supported the object by providing stability so it would fall straight down and not at an angle. If we were to drop it using our hands rather than a pulley, this could increase human error because we would not be able to drop it straight down.…

    This experiment was to use kinetics of projectile motion and free falling bodies to determine the distance a ball will travel after it hits a bounce plate. To determine this we had to use the equations x=(1/2)at2 and v=v0+at and derive an equation that will determine the distance the ball will travel based on the height of the bounce plate and the height of where the ball will be dropped above the bounce plate. The equation made was g*(sqrt(2)/sqrt(g))*(sqrt(H)*sqrt(h)). From here we can make an estimate of how far the ball will travel after it hits the bounce plate.…
