Marble Investigation

Step 4. now grab the end that you just tied. Put the tied end on the stick, and hold it there with your thumb. Then pull the

o Start with the small marble and drop it from 10cm, do not apply any force to the marble and make sure it lands somewhere in the middle of the tub.

First, the meter stick did not have perfect ends. This caused uncertainty because the measurements were not accurate. The meter stick was not compared with others to see if it was reasonably close.

2. Using the protractor, measure the angle of the ramp making sure the angle of the ramp is 10˚.

· I set up the apparatus as shown in the diagram. I then placed a

Step 4: Then grasping both points bring your left hand up through the middle to the left of your neck making sure the right end hang stays in the middle.

In our graph of the average times it took the marbles to go down the roller coaster, it is shown that there is an optimal or best amount of mass for the marble to be in order to have the fastest time. Marble four, or the second largest marble, had the fastest average time. As the mass of the marbles increased, their time increased as well, making marble five slower than marble four because its mass was greater than the optimum mass. Marble one, two, and three were also slower than marble four because its mass was less than the optimum mass.

If the Roller Coaster base was more stable and didn’t move as much that would help it go faster. If the tracks had more sharper edges and properly made, it wouldn’t get stuck so many times and go faster. All these reasons play role for our marble getting stuck in certain places, not going fast enough, and it having it bad design. This put a lot forces and friction on the marble, making it not reach full potential. This means that marble needed more force to get more tricks, If the track at beginning had a bigger downward slope.

Which mass of marble would travel down a roller coaster the fastest? Well It starts with Newton´s laws of motion. The first law of motion states that a force has to be applied to an object to make it accelerate. The second is a formula that calculates how much force is needed to accelerate an object and how it changes according to the mass. Also third states that there´s a equal and opposite reaction for every action. That means that in every interaction, there are acting forces on the two interacting objects(Jeff, Zeilinski)

The purpose of this experiment is to research the physics related to roller coasters and inversions. And the main question that I intend on answering is “how easily does energy dissipate?” I plan to find whether or not a single marble, after dropping from a small height, can complete a single vertical loop constructed from foam tubing. To elaborate, I will be building a shuttle-style coaster with foam tubing as track with tape as supports. This will be connected to a tall tower with several terraces that I will drop marbles from. This will be followed by a vertical loop, and then a switchback tower that will lead to the marble traveling backwards and eventually losing its energy. For data, I intend on measuring three things. First, the height

The question that was asked and answered from this experiment was if the size of the wheel affects the distance traveled. The hypothesis was that if the spool size is larger, then the spool will travel farther. The independent variable is the spool, while the dependent variable is the distance traveled. The control variables were the ramp height, the place the experiment took place, and the material of the ramp. The procedures for this experiment were to: Get 3 spools- a large, medium, and small. Get a ramp and elevate it 5 centimeters off of the ground. The spools shall roll down the ramp three times each, in roughly the same spot.

The equation h = d (h/L) was used to calculate the height of the cart on the ramp

On the circle of the grey rectangle, attach the small gray square with the hook.

To determine the speed and rate of acceleration of a toy truck rolling downhill on a ramp at varying angles.

In rolling down the ramp, part of the ball's initial potential energy was converted to heat energy due to friction. Because the loss of energy due to friction was not accounted for in the derived equation, an average acceleration of 7.21 m/s2 differs slightly from the actual acceleration due to gravity that the ball experienced. Additionally, conservation of energy principals do not account for the effects of air resistance on the metal ball. Therefore the actual acceleration of the ball due to gravity would have differed slightly from 7.21m/s2. The accepted value for
