The pendulum was pulled to about 15 cm from the motion detector. In case of the mass on a spring, the mass was pulled till just a few inches away from the motion detector.

The object furthest to the right is the motion detector that will measure the object's position and time and send it to the LabQuest. The object to the far left is the stopper that will stop the cart after it has completed its run. The materials we needed to complete this lab was a motion detector, a cart, ruler, cart track, and LabQuest. The motion detector measured the time as soon as the cart was set in motion and delivered the data to the LabQuest. The cart was used to measure the velocity for each run. The cart track was the medium we used to push the cart down and collect

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

A. Water boils at 100°C at sea level. If the water in this experiment did not boil at 100°C, what could be the reason?

This supports our hypothesis that the amplitude being adjusted doesn't effect the rate at which it swings. Now we move on to our question: Would mass be a factor? The first bob was replaced with something much smaller in weight. We returned the displacement back to 10 cms while keeping the length the same. We recorded the 10 periods and the average seems to be around the same approximate rate of 2.01. This debunks the theory of the pendulum being dependent on mass. Changing both the displacement and weight seems to not affect the rate in anyway.

-“The period of the wave is 4.0 m.” This sentence is wrong because period’s unit is second(s) or minute(s), etc. Period does not measure distance, it measures the time one particle takes to complete one vibration so it cannot be in meter.

Loosen the retaining screw and adjust the horizontal arm to the dimple that produce the 2nd largest radius between the spinning mass and the rotating shift. Allow the spinning mass to hang straight down, without being connected to the spring. Position the pointer directly below the tip of spinning mass and secure the pointer to the base. Use the scale located on the base to determine the radius, r, of the pointer from the rotating shaft. Record this value onto Data Sheet A. The experimental uncertainty in r is estimated to be the width of the spinning mass tip – approximately 0.2 cm.

In the clothespin lab, we shot a marshmallow placed on a clothespin by applying force to the longer end of the clothespin and calculated the distance the marshmallow was shot by measuring our pace, walking from the clothespin to the spot where the marshmallow first hit the ground, and then converting the amount of steps (paces) it took to walk to the marshmallow to

* The relevance of this experiment is similar to understanding a real airplane. Paper airplane models are derived from an actual plane these days. The design of an airplane has so much to do with distance, hang time, speed, and many other factors. Understanding the models I have chosen to make help me

Measure the length of the string from the ring stand to center of mass of the stopper. It should be around 10cm. Record this length in the data table.

As a result of trail and error method we find the angle for the third pulley and the mass that should had be suspended from it. This will balance the forces deployed on the strings due to the other two masses. While the third force is defined as the equilibrant (������⃗������) Since it is the force that establishes the equilibrium. It is also the negative of the resultant -������⃗������ = ������⃗������ = ������⃗ ������ + ������⃗������. We gathered and recorded the mass and the angle required for the third pulley to enable to put the system into the equilibrium in table 1.

In this experiment, we experimented finding the fundamental quantities of length, mass, and time using many laboratory tools. We used a Vernier caliper, stopwatch, rulerm meter stick, wooden block, metal block, Dial-o-gram, different masses, and circular objects. We took into consideration the uncertainties of many different tools and objects into our experiment. The inherent uncertainties of different measurements and ways to propagate those uncertainties were learned during this experiment.

Purpose: The purpose of this Physics Lab is to investigate what factors determine the amount of flexion of the cantilever. Hence, the objective is to establish a relationship between the length of a cantilever, which may give some insight into the physics of cantilevers.

Table 1 & 2: First, find the mass of the wooden block and record the data. Then place the wooden block on the inclined plane (at 0o) with the wide side down. The height of the pulley should be the same height as the screw location on the wooden block. Then hang a weight on the opposite side of the hanger and add weights until block starts to move with a constant velocity (push block to overcome fs¬). Then record the resulted weight of the hanger in Table 1 (as F). Add 500 g to the wooden block and repeat the process. Replace 500 g with 1 kg on the wooden block. Repeat the process described above.
