Where mass 1 is the mass of the cart and the weights it contains, while mass 2 is the hook and the weights it holds. Thus the goal is to record data that follows this equation; as more masses are added to the hook,

The mathematical relationship between the initial heights and distances proved to be y=17x. In Table 1, the initial heights and distances were converted from inches to centimeters (the values were multiplied by 2.54) to showcase the data through a graph. Figure 2 displays the heights and

with the accepted value of 9.8m/s^2. In the second experiment, acceleration of a cart traveling down a slight incline was measured with a two photogate method. Gravity was calculated and yielded a value of 8.7429, a bit lower than the accepted value of 9.8 m/s^2. The third experiment was

The aim of this experiment was to establish whether speed affects braking distance of a car travelling down a ramp at different heights.

The purpose of this lab is to find the mathematical relationship between the height from which a round object is dropped, and the speed at which it travels when it reaches the ground. This experiment will achieve the goal by measuring the height at which a sphere will be released on a ramp, and recording the time and distance the sphere will travel when it reaches the ground. By analyzing and projecting the quantitative data on a graph, and finding the best fit line will indicate the existing relationship between the two variables, height and speed.

chains with each composed of hundreds of amino acids. Catalase is used to prevent the toxicity of hydrogen peroxide formed by byproducts. The primary reaction for this lab will be the decomposition of H2O2 into oxygen and water. We will add in catalase because it is very slow to react. One of our main objective for this lab is to calculate reaction rate due to the catalase. Although we cannot fully determine how much water and oxygen is produced in this experiment, we can definitely determine

On one side of the meter were acting two masses and in the other just one mass. These masses were located at different distance from the pivot point. The two masses on one side were: 0.268kg (m1) at 0.1m (d1), and 0.218kg (m2) at 0.3m (d2), in addition, the 3rd mass needs to be at 0.3m (d3). Therefore, we made the equation: (m3) (g) (d3) = [(m2) (g) (d2)] + [(m1) (g) (d1)] and then, m3=( [(m2) (g) (d2)] + [(m1) (g) (d1)])/((g) (d3) ). The resulting m3 was 0.307kg. After placing the obtained mass at the stated distance (d3), the meter stick was

Hydrogen Peroxide is a by product of many biological and chemical functions of organism. Although it is toxic, it still remains in our cells. To counter the hydrogen peroxide we produce something called a catalase. This means that with a catalase, it can cause the chemical reaction to speed up the reaction of the Hydrogen Peroxide so that it does not come in contact with our cells.

As the first lab of the Physics 2 curriculum, our class completed a lab experiment that introduced us students to a new concept that would be a foundation to the future topics that we learn in this class. In this lab activity, we used a lab cart on a flat track to compare the collision of the cart with a force sensor with and without the plunger during different trials. The materials that we would need for this activity are a lab cart on a flat track, a timer, a force sensor, and a Ti-Nspire Calculator. The Ti-Nspire Calculator was connected to the force sensor in order to track and create data that would be shown in graphs on the calculator. Because we had to compare the collision of the cart with

Measure the mass of the trolley and measure the mass of the mass piece used.
