The main purpose of this experiment was to verify the relationship between the mass of an object (among three objects) and the lever arm of one of the other objects on a seesaw according to their torques. Due to the theoretical equation that we found we hypothesize that there will be a linear relationship between the third mass and the first mass’ distance from the fulcrum, which is called lever arm. Also, because a graph with that equation was reached, and since it perfectly matches the equation for linear lines, y = mx + b, we have proven our hypothesis. This relationship means that if we double the third mass (m3), the lever arm of the first object (l1) will be doubled as

rate of fall of an object was determined by its weight held that matter was constructed out

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

Seven various household objects were chosen to measure using a digital gram scale. Each object’s mass was estimated by lab students and recorded in data table 4. A quarter, ball point pen, rubber bulb, large paper clip, green crayon, house key and a copper penny masses were estimated and recorded in data table 4. Each object was placed on the scale individually and its actual measurement was recorded in data table 4. As we started estimating the household objects we were often not correct in our estimations. As we measured more and more objects, we got better in our estimations by comparing objects with known masses and comparing them with the unknown

An experiment was set up with the goal to prove a hypothesis created, which stated that the mass of a marble would not have any effect in the acceleration of that specific marble as it moves down a ramp. During the testing of the hypothesis, the data collected demonstrated that the acceleration of three different marbles with different masses were nearly identical, which reinforced and proved the hypothesis. Acceleration is the rate at which the velocity of an object changes, and velocity is the speed of an object in a specific direction. To test the hypothesis, a marble had to be released right behind a photogate on a ramp, which was placed on the tenth hold. As a consequence, it was impossible for the marble’s time to be recorded with an

The hypothesis is that the hooked mass used on the pulley to keep the cart stationary on the ramp is equal to the mass of the cart. The hypothesis is invalid, it is not supported by the data. Mass is a the amount of matter in an object so it always remain the same. As shown on the table, the hooked masses vary depending on the degree of the incline so it cannot be the mass of the cart. In addition, the correct calculation of the mass of the cart proves that the hypothesis is wrong. For the 15 degree incline, the mass of the cart is 19.3kg while the hooked mass is .050kg. This clearly shows that the hooked mass used on the pulley to to keep the cart stationary is not equal to the mass of the cart. For the 20 degree incline, the mass of the

The goal of the experiment was to identify the gravitational acceleration from the recorded distance(cm) vs time(sec) data of a fallen object. The first step was to graph the distance-time graph from the data collected. Upon graphing the data, the best fit line was identified in order to find the formula of the function. As the data is representative of a graphical parabola, a parabolic function was utilized to be the best fit trendline. The function Positon=404.289cm/s^2(t^s) + 44.450cm/s(t) +4.876cm was identified. In the equation, 404.289cm/s^2(t) represents the slope of the parabolic curve pertaining to the distance(cm) over time(sec) as the 4.876cm displays the y-intercept in which the function crosses the axis leading to the resulting curve. From identifying the distance-time graph equation, the next step is to find the velocity of the set data.

The kinetic energy lost in each experiment was 68.9%, which tells us that when

J.B van Helmont’s Willow experiment taught the world a whole lot, not just with the scientific method but it also taught us about trees and where the mass comes from. Helmont wanted to find out about the mass of a tree, so he chose to do an experiment. Van Helmont had a hypothesis, his hypothesis states that the mass of tree comes from the soil, which is what majority of college students today say. But he had to prove that first.

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.

Step 9: Because we measured the lengths in centimeters rather than meters, we need to calculate are ‘g’ value into m/s2 so we can compare it to the SI unit for acceleration due to gravity. (Eg. 981.4/100 = 9.81 m/s2)

In the first part of the experiment, the fundamental quantities-length, mass and time were estimated simply by guessing. Even though it can be helpful sometimes to test a hypothesis, huge percentage errors in the measurements showed that human errors can be significant and therefore, we need more sophisticated techniques for more accurate measurement. For instance, using Vernier calipers is more precise than guessing the length or more accurate than the ruler.
