Collision Physics Lab Report

Students in an AP Physics lab perform an electrostatics experiment involving two charged spheres suspended

To begin the experiment, we measured the masses of the two stoppers and the eye bolt used to secure the stoppers that we were using in our apparatus. The mass of the first stopper was 18.8 grams and the mass of the second stopper was 50.5 grams. The mass of the eye bolt was 11.6 grams. The mass of the screw and bolt that secured our hanging mass was given to us as 25 grams. After, we chose six different hanging masses based on stopper mass. We made sure that the hanging mass was always larger than the stopper mass or else we would not be able to get the stopper to spin at a constant velocity. The first three mass ratios we chose was using the stopper with the mass of 18.8 grams and then we used a hanging mass (the mass of the screw and bolt is included) of 65 grams, 85 grams, and 105 grams. This gave the three mass

First, The procedures of were take an energy car and roll it down a track with a without a sail and record the data from photogate A to B and the time to took to get there make sure the photogate are 555 cm away from each other. Do the same one energy car wit just wheels and one with one 3 times each.

In the first experiment, “ How does mass affect your game?” it shows that the data on “Ball- Mass 3” that the 10 pound bowling ball had the highest kinetic energy of 27(J), the greatest velocity (m/s) of 3.42, and in average it produced 4 bowling points. According to the data, on “ Ball- Mass 1” the 11 pound ball got an average velocity (m/s) of 3.14, the kinetic energy of 24 (J), and the average bowling points of 3. On the other hand, the evidence shows that the 12 pound bowling ball in “ Ball- Mass 2” has the velocity (m/s) of 3.12, the kinetic energy of 23 (J), and the average bowling points of 4 . Concluding that in my Game 1 the velocity of the masses of the bowling balls decreased when the bowling balls were heavier and that the kinetic energy was lower as the mass increased in the bowling balls.

This science fair project will test which antacids are most potent in neutralizing lemon juice. When an acid and a base combine the base will neutralizing the acid in a chemical reaction; this is how antacids work as well. Antacids are substances that will neutralize stomach acidity which in return relieves heartburn, indigestion, or stomach pain.

From the first test, which had the dummies sitting upright, and the data was: 41ft/sec, 54 milisec collision time, and 21g-force exerted on the

The problem of the experiment is: which metal out of galvanized iron, copper, stainless steel, and steel will rust the least in acetic acid? The hypothesis is: If Copper is placed in the acetic acid then it will be the material that loses the least mass when mass lost is related to material submerged. The independent variable is what type of metal is being used. The dependent variable is the percent of mass lost while submerged in the vinegar. The controls include the amount of vinegar per sample, the same person pouring the vinegar, the same scale taking measurements, and the same amount of time submerged in the vinegar. The standard of comparison is how much the mild steel corrodes because that is the metal currently used to make the gas tanks at gas stations. The experiment designed to test this starts with cleaning of five different samples of copper, iron, mild steel, and stainless steel. After that, the mass of each sample is measured using an electronic balance. Then, each sample is put in a cup, and submerged in 200 mL of vinegar. They are then left in the vinegar for about 24 hours. Next, after the 24 hour period, each sample is then taken out, cleaned, and measured again. This process is repeated one more time. After the experiment is done, you calculate the percent of each sample lost by day, and find the average of those. Then, the metals are compared by percent of mass lost to find the most corrosion resistant.

The significant data shows a difference in the time needed for the various positions in a Dodgeball court. Given the size of the court and the various combinations of distance achievable, the experiment has shown that the four horizontal paths (1, 2, 5, 6) are generally shorter than the four diagonal paths (3, 4, 7, 8) with a direct reflection of their given times of flight. In this case, an individual along path 2 would not have sufficient time to recognize and react to the ball given the variability of the reaction time and velocity of the ball. Therefore, the data as specified proves that the distance, reaction time and velocity all play an important aspect in the game of dodgeball, when the results are analyzed, it will show the correlation

Friction Lab Formal Report Tayado Langley 12/10/14 Period 1 Abstract This experiment was created in order to enhance our understanding about the causes of friction. This was achieved by testing the friction on various surfaces. The first thing I did was gather the materials ( a bottle , some blocks of wood , string and surface materials.) Then I attached the string to the block of wood and the bottle.

The total momentum and total kinetic energy before and after do not match up because the final momentum and kinetic energy is smaller in the straight on collision and larger in the nearly straight on and glancing blow. For kinetic energy to be lost like in the straight on collision means that the kinetic energy was transformed into another type of energy like sound because in real life when the balls collide, a sound can be heard during the collision. However for kinetic energy to be gained does not make sense, meaning something was wrong with the apparatus or calculations. Part of the results do reflect the theory since for the straight on collision, the most of the velocity from the blue ball is transferred to the red ball. And in the nearly straight collision and glancing blow both balls have

Purpose: The purpose of the practical is to find how mass affects acceleration and how it affects also the force of the accelerating body. To do this we are going to do the ticker tape experiment where an accelerating body pulls a tape through a consistent 50 dot per second ticker timer. The acceleration body in this experiment will be a small trolley pulled by a string that is pulled by the downfall of different masses which will then tell how mass affects acceleration.

The forces that are involve with the experiments are basically focused on the concurrent forces. The experiment also allows us to develop the condition of balancing or arranging the angles both sides on a force table. This laboratory experiment allows us to take the mathematical abstraction of a vector to make it tangible as possible. This experiment will look into two ways of

HYPOTHESIS: Without the effects of friction the momentum will be conserved in the isolated system. In all three experiments the momentum before the interaction will equal the momentum after the interaction.
