When the standard cart reached the plunger cart they collided, stuck together, and continued down the track with a new velocity. The standard cart was pushed towards the plunger cart, which was at rest. (Read Section 7 -3 for a thorough explanation of the W ork-Kinetic Energy Theorem.) I'm not able to just leave it out in the public since Reddit will take it down because of copyright, lol. (a) The balls will not move because K1=K2K_1=K_2K1=K2 before the collision. 1001 LAB 3: CONSERVATION OF ENERGY 1001 Lab 3 2 which is called the kinetic energy of the ball just before it hits the ground. endobj Even thought Ionic bonds still hold molecules together, they are weaker than covalent. Overall the __________ (kinetic plus potential) is conserved. The equation for GPE is mass multiplied by acceleration due to gravity, multiplied by height: Acceleration due to gravity is always 9.8m/s2; however, it is acceptable to round this to 10m/s2 for easier calculating. This was a result of miscommunication between group members that proceed to affect why the group had the lowest measurement of displacement. If students have difficulties differentiating the characteristics associated with covalent and ionic bonding, they will suffer with future topics and other branches of chemistry. KE lab.docx - Kinetic Energy Lab BY: PAYTON LANE Physics Ionic bonds form their bond when opposite charged ions in a chemical compound have an electrostatic attraction. In the lab, the aim was to get as close as possible with both accuracy and precision when determining the mass and volume of the spheres.

In this lab this was analyzed in multiple collision situations. You are never to simply list answers to considerations. In other words, energy cannot be created or destroyed but it can be converted from one form into another. 2. endstream endobj 499 0 obj <>stream Other researches had similar data but were never exactly the same. 3. An example of an elastic collision is a cue ball striking a billiards ball initially at rest. Discussion: The Work/Energy Equation says "The work done on an object by the net force on it equals the object's change in kinetic energy." or, in symbols: Whenever an object moves, some energy is converted to heat through friction. Upon graphing the data, the best fit line was identified in order to find the formula of the function. The values of the momentum ratio are very close to one which indicates that the momentum is conserved in the experiment. Then remove the .75m desk and place it on the ground. Energy Skate Park: Basics - Conservation of Energy | Kinetic Energy Allow the temperature to stabilize, and record this initial temperature to the nearest 0C The major finding was the return bounce height depended the most on the balls mass and from where it was dropped. Ionic bonding is a type of chemical bond formed between two ions with opposite charges. The Photogate sensors were used to measure the velocity of each cart as it moved from the explosion site. If a ball is sitting still at the top of a hill, will it have GPE or KE?

All objects have momentum, even if it is zero, and momentum cannot be lost. stream L. C. Measure the change in temperature for different materials and mass. This would force the carts to stick together after collision. a. We used the equation Y=mx+b, in order to compare the velocity of each trial by comparing the slope and the y-intercept. C is a nutritional symbiont. To begin the lab a Vernier Dynamic Track was set up and leveled on a table. - h is the maximum height of the object relative to the level of reference chosen. temperature. The initial velocity of the standard cart and the final velocity of the plunger cart were the readings from the first and second Photogate sensors, respectively, on the Logger. The nonconservative work is the _________________________, Conservation of change in kinetic energy formula, Lab 9: Centripetal Force & Rotational Dynamics, Mathematical Methods in the Physical Sciences. Hold the test tube with a test tube holder and heat the outside of the test tube with an aim and flame lighter until the wax melts. The balls have equal kinetic energies (k1=k2)(k_1=k_2)(k1=k2), but ball 1, which is coming from the left, is moving faster than ball 2 (v1>v2)(v_1>v_2)(v1>v2). Covalent bonding is a root within Organic and Biochemistry that needs to be understood in order to fully understand the theories and concepts discussed in both forms of chemistry. any higher. Fill close to the 0 mL line but not higher, or you will not be able to measure volume accurately. The equation for KE is 0.5 multiplied by mass, multiplied by velocity squared: If you're struggling getting the time exact, try doing the experiment with two people. You probably found that your values for KE were slightly less than that of GPE. As well as identify how accelerations affects an object's velocity and time. Measure out approximately 50 g of aluminum wire using a mass balance. This was done by causing elastic collisions, inelastic collisions, and explosions of carts on a Dynamic Track. Key points: When you leave the EdgyBot to do work by itself, you need to stay on the same tab. Place the calorimeter (no lid) on the balance and tare the balance. This button released the plunger, and propelled both carts down the track in opposite directions. Kinetic energy (KE), the energy of movement, and gravitational potential energy (GPE), or stored energy due to height. As the height decreases the GPE will ________ while its kinetic energy increases. I made this because I was having to do all the research and I would've loved it, if someone had already done this. Kinetic Energy Practice Problems 1. Data are reasonably accurate. Acceleration is an objects increase in velocity. mL cylinder to the beaker on the stir plate and empty it into the beaker. If the cart maintains at a constant speed, then the cart will have an increase in acceleration. b. If needed, place the calorimeter into a beaker or other secondary container to prevent wobbling. The first Photogate sensor measured the velocity of the standard cart, and the second Photogate sensor measured the velocity of the plunger cart. b) Load the HCl and NaOH burets with HCl and NaOH solutions, respectively. This taught the very important concept of the conservation of momentum. It goes from 414.2 kilometers per hour (kph) to 0 kph in 2.8 seconds. 4. You'll be measuring the GPE of a ball 4 meters off of the ground and comparing it to the measured KE right before it hits the ground. then place a thermometer in each cup and observe the readings until they do not climb Where: In inelastic collisions the objects stick together after they collide. at a height of 10 cm from the materials. There were no controlled variables used in this experiment. When collisions occur, two properties of the colliding bodies are changed or transferred: their Energy and Momentum. PDF Energy Lab Key - Southeast Missouri State University There are four equations that can be used in both one-dimensional kinematics and two-dimensional kinematics. 100 g (least massive) Measure the height from which you'll be dropping your tennis ball. a. Joule (J) 5. What is its volume at s.t.p.? Additionally it showed that kinetic energy is only conserved in elastic collisions. This is based on the equation .5mv^2=.5kx^2, where m is the mass of the duck, v is the velocity of the duck in the air, k is the spring constant of the spring in the base of the duck, and x is the displacement that the spring is compressed. Describe the three different types of bonds, providing examples of molecules formed through each type of bond. Read through the scenarios below and calculate the predicted change in kinetic energy of the object compared to a 50 kg ball traveling at 10 m/s.
