We can say that one form of energy (potential energy) is converted in another form of energy (kinetic energy). The purpose of this lab is to test substances and to determine the physical and chemical properties of substances. 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. WorkKinetic Energy Lab Included, labeled and organized all parts of the lab report. When the standard cart reached the plunger cart they collided, but did not stick together, and the plunger cart moved down the track. 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. No items have been added yet! 1. The first condition tested was elastic collisions. On the Logger. b. I. 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. The energy of a moving object is called kinetic energy. In a car, the chemical energy stored in the gasoline is released when it is burned in the engine; that chemical energy is ultimately converted to kinetic energy and results in the motion of the car. The work-kinetic energy theorem states that the change in the kinetic energy of a particle during a displacement is equal to the work done by the resultant force on the particle during this displacement. Draw a circle, an X, or place a piece. One cart was a standard cart with a rod on top. The Logger Proprogram was set up so that it would collect the Gate Time from each Photogate sensor. An ionic bond is a type of chemical bond that occurs when one atom loses an electron to form a positive ion and the other atom gains an electron to form a negative ion, which then result in attraction. Fill close to the 0 mL line but not higher, or you will not be able to measure volume accurately.

If the slope was steeper on the graph, this meant that the cart had an increase in velocity. other two cups, filling one with 100 g of wet sand and one with 100 g of dry sand. and our Understanding of DG =G 2-G 1, the driving force A thermodynamically favorable reaction or process means DG < 0, that's to say, highly driven! This experiment will be exploring, in depth, Newton's second law. lab notebook. Before you start, make a prediction: Will the GPE at the top be the same as the KE at the bottom? b) Swirl the thermometer slightly, and confirm that the thermometer is well within the water. Open Edgenuity and enter the purchase key. The other cart was a plunger cart, which contained a spring activated plunger that could push the carts apart. These values were recorded, and the procedure was repeated five additional times for a total of six readings. KE = mv2 KE = ? Because the percent differences were relatively close to zero the momentum of the system was conserved. 4 0 obj These values were recorded, and the procedure was repeated two more times for a total of three readings. The ______________ is happening in the presence of conservative forces like gravitational forces or the force in a spring. 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. If you have access to a supervised laboratory, do Part A. I'm not able to just leave it out in the public since Reddit will take it down because of copyright, lol. A 50 kg ball traveling at 20 m/s would have kinetic energy. Create your account.

(c) The balls will move to the right because v1>v2v_1>v_2v1>v2 before the collision. As the height _________ the GPE will decrease while its kinetic energy increases. Newton's second law says: Force equals mass times acceleration (F= m x a). Double-click the bottle of NaHCO3 to move it to the Stockroom counter. I've been adding the answer key to my World History and Biology course. When the standard cart reached the plunger cart they collided, stuck together, and continued down the track with a new velocity. Then push the duck so it is compressed and is going to launch horizontally . these samples. In each calculation below the initial momentum is calculated using the following formula. In this experiment, we will collect data on velocity, speed, and time. I'm remaking this, so it'll be more coherent. - g is gravity (not to be associated with the acceleration due to gravity because g is a scalar) Write the goal of the lab or the question you tried to answer. In physics momentum is always conserved. The Great Depression and the New Deal How did the New Deal affect minorities in the United States (African Americans, Hispanics, etc.) She is also certified in secondary special education, biology, and physics in Massachusetts. Add water to the cup until the total mass reads 200 g. Repeat As the data is representative of a graphical parabola, a parabolic function was utilized to be the best fit trendline. Energy Skate Park: Basics - Conservation of Energy | Kinetic Energy They should start immediately when you drop it and stop it exactly when it hits the ground. The carts were placed on the track so that the magnet containing ends of the carts were facing each other.

In explosions the kinetic energy increased greatly after the explosion occurred. The cell membrane functions to protect a cell and to regulate the movement of molecules and ions into and out of cells. This friction converts some of the energy of the ball into heat, making the value measured for KE less than expected. If a person riding a bike has a mass of 200 kg and is moving at a velocity of 5 m/s, what is their kinetic energy?

She has a Master's Degree in Cellular and Molecular Physiology from Tufts Medical School and a Master's of Teaching from Simmons College. hd C. Measure the change in temperature for different materials and mass. To determine whether the height at which a marble is dropped affect the size of the crater. Did your experiment follow the law of conservation of energy? It can be proven that there were multiple sources of error by the slope of the equation on the Force vs. Acceleration group for this lab. a. Joule (J) 5. Kinetic energy is a property of a moving object or particle and depends not only on its motion but also on its mass. stated britannica editor Erik Gregerson. Place the lid on the calorimeter, and insert the thermometer. We wrote down our data to prove that speed, height, and mass affect kinetic energy. According to the data, on Ball- Mass 1 the 11 pound ball got an average velocity (m/s) of 3.14, the kinetic energy of 24 (J), and the average bowling points of 3.

Practice dropping the soda bottle so that the bean bag pops up straight and, can have its height measure with the meter sticks. This was done by causing elastic collisions, inelastic collisions, and explosions of carts on a Dynamic Track. If your time is greater than it's supposed to be, your results won't make sense. Step 1: Gather materials. These calculations illustrated the nature of momentum, and showed that momentum is always conserved. This rod would be used to break the photon beam in the Photogate sensor, and send a signal to the computer. You probably found that your values for KE were slightly less than that of GPE. These sensors were attached to a computer, which was running the Logger, program, through a Vernier computer interface. kinetic energy to object 2. Half-Life Data-Teacher Answer Key 1.Hypothesize what halflifeis: Halflife is the amount of time it takes for approximately half of the radioactive atoms in a sample to decay intoa more stable form. This would force the carts to stick together after collision. The values of the velocities were shown on the Logger. and the calorimeter water.
