Centripetal Acceleration Lab Report

An object was placed or hanged on the proper area, where it could sit at rest. That is to say an inclined track for the cart, and a ring stand for both the pendulum and a mass attached at the end of a spring. Hereafter, a motion detector was connected to a computer via a lab quest and was brought in close proximity with the object. After that, the motion detector sensitivity switch was set to ball/walk or track depending on the object’s motion which is being studied. From here, the appropriate file for plotting an object’s graphs was opened on the desktop. Then, from here, everything was in place for data collection. (Photos below).

The independent variable of this experiment are the environmental factors that you are testing on the rate of transpiration, so our independent variables would be bright light, fan, dark, and misted. The dependent variable is the rate of transportation because this depends on whatever environmental factor the plant is placed. The constants were things like the type of plant we used, the room temperature, the type of scale we used and how far the fan/light was placed from the plant.

The purpose of this lab was to test the relationship between velocity, position and time. As well as identify how accelerations affects an object's velocity and time. In this experiment, we will collect data on velocity, speed, and time. We used the equation Y=mx+b, in order to compare the velocity of each trial by comparing the slope and the y-intercept. If the slope was steeper on the graph, this meant that the cart had an increase in velocity. If the cart maintains at a constant speed, then the cart will have an increase in acceleration. In class we learned about the principles of acceleration, time, and velocity. Acceleration is an object’s increase in velocity. Velocity is how

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

Set the radius to 2.0 m, the mass to 1.0 kg, and the velocity to 10.0 m/s.

where kv is the velocity constant determined by the flux density of the permanent magnets, the reluctance of the iron core of the armature, and the number of turns of the armature winding. w a is the rotational velocity of the armature.

The art of Fidget Spinners. As it becomes a massive hit, this spinning fidget toy grows into something more than only a fidget toy. It becomes some sort of art, and quite number of people are into it. At first, we start with some boring-designed-fidget spinners. They were mostly plastic, and they are molded in one colour. But as the trend invades, there are tons of design modifications. Today, fidget spinners come in a ton of different colours, shapes, and material. They used to only have 3 “wings”, but now, some of them have 2, and some even have more. You could even get a gold plated fidget spinner if you wanted

10. How does varying the frequency effect contraction force? Which interval caused the greatest contraction?

The main objective of this lab was to measure the friction force it takes to start moving a weighted block across a table, and as it continued to move. This force was tested experimentally in three separate ways. The force was then solved graphically and mathematically through six different runs per method. TALK ABOUT RESULTS HERE.

The objective of this practical is to determine acceleration due to gravity ‘g’ using the simple pendulum model. This is shown when a period of oscillation is seen to be independent of the mass of the mass ‘m’.

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.

* Dependent Variable: The deflection/flexion of the cantilever in metres. This will be measured indirectly by measuring the initial height of the bottom of the cantilever with no mass added (which is equal to the height of the table) and the new height of the bottom of the cantilever after each trial, which will be measured with mass added. Hence, the difference between these heights is equal to the deflection/flexion of the cantilever. The material and other physical properties of the cantilever will be controlled by using the same yardstick as a cantilever for each trial.

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.
