Acceleration Lab

The explanation for the variation in data and inconsistencies in the data is because the string that is propelled by the mousetrap was wound up by different group members(REFER TO GRAPH AND TEXT BELOW)

In this experiment, the signal generator was set so that the frequency meter showed a reading of 1,803 Hz. The microphone was moved to a distance from the speaker so that the oscilloscope displayed a straight diagonal line. This position was of the microphone was recorded as the initial position, or beginning of a wavelength. The microphone was then moved farther in the same direction until the oscilloscope displays the same horizontal line. This position was recorded as final position, or the end of the wavelength. The distance between the two positions represents one wavelength for this frequency. This was repeated for frequencies of 2,402 Hz, 3,002, Hz, 3,602 Hz, and 4,201 Hz.

Moving along, to the second experiment, “How does force affect your game?” concludes that using a 10 pound ball applying strong force provides a velocity (m/s) of 3.2, a result of 25 (J) for the kinetic energy, and 5 bowling points

This was due to the formulas used to calculate the actual velocity and acceleration: 2πr/t for speed and v2/r for acceleration. As for the other forces identified within the lab, the force of air resistance equaled the net force and allowed the flying cow to travel at a constant velocity.

Conclusion: The results of this lab were found through seemingly simple equations, basing all of your work off of data such as time and distance can become frustrating due to human inaccuracy, but the results show the height and initial velocity of the marble. The results are all reasonable compared with the beginning values that we collected during the lab, and even without calculations fit into the equation. The concept of projectile motion was the basis of this lab, focusing on using kinematic variables and equations to find the

In this lab, we applied the concepts of velocity,force, acceleration, time, and distance in order to calculate which trial had a higher velocity. We also learned the relationship between each of the factors and how altering one plays a role in the other factors. For example, if we were to apply more force the velocity of the cart would increase, as well as the amount of time it took for the cart to go down the

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

Kinetic Energy is the energy of movement, whether it is horizontal or vertical, it’s kinetic. There is many different types of kinetic energy. There is; vibrational, rotational and translational (the movement from one location to another. IN our experiment we also have kinetic energy. The particles that move around need kinetic energy to bond because if the particles wouldn’t have kinetic energy, they wouldn’t move, then they wouldn’t be able to collide and at last there would be no chemical reaction taking place. But for a reaction to take place there has to be enough kinetic energy to overcome the bonding forces of the reactants. The minimum amount of kinetic energy need to cause a chemical reaction is called activation energy (symbol: Ea

In this lab I was able to correctly identify all of the given objects by measuring their masses and volume to correctly get their density. I was able to properly identify the

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 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

On the graph there are some minor anomalous results such as trial 3 of mass 200 gram, where the acceleration is 0.2m/s^2 closer to the 500 gram average then the average of the two other trials for 200 g force. Outlier could be caused by multiple factors such as incorrect or inconsistent method of dropping the weight or the miss positioning of the trolley creating an awkward starting angle and direction.

Theory states that T and d are related by the equation: T2 = kd3+ (4π2 l)/g where g is the acceleration of free fall and k is a constant.

With the use of this experiment some conclusions have been drawn. For instance the main result is that the friction increases if one of the following variables increases: the weight of the box, the size of the box and the weight that is being pulled.

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.
