Physics Lab - Work & Kinetic Energy (uses Science Workshop TM Interface) Purpose: The purpose of this lab is to compare the work done on an object with the object's change in kinetic energy. The goal of the experiment was to identify the gravitational acceleration from the recorded distance(cm) vs time(sec) data of a fallen object. When the standard cart reached the plunger cart they collided, but did not stick together, and the plunger cart moved down the track. The Just Drop It investigation was very informative and taught important lessons. In this lab this was analyzed in multiple collision situations. Simply put, his law describes the relationship between the mass of an object, the acceleration of an object, and the force needed to move it. Each chemical compounds has a certain percentage of ionic character in its bonds and the remaining percentage as covalent bonds. Explain your answers. The mass was determined by weighing the spheres on the Analytical Scale and Triple Beam Balance Scale. We know that the law of conservation of energy says that energy can never be created or destroyed, so what happened? As well as identify how accelerations affects an object's velocity and time. Make sure you record the mass in kilograms in your notebook. Click the Get form key to open the document and move to editing. However, when the group was compared to other groups conducting the same experiment, the displacement of their marshmallow was the shortest.

You probably found that your values for KE were slightly less than that of GPE. We wrote down our data to prove that speed, height, and mass affect kinetic energy. 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. a. Joule (J) 4. These calculations illustrated the nature of momentum, and showed that momentum is always conserved. Momentum cannot be lost in a collision. We can say that one form of energy (________) is converted in another form of energy (kinetic energy), We can say that one form of energy (potential energy) is converted in another form of energy (_________). These sensors were attached to a computer, which was running the Logger, program, through a Vernier computer interface. Draw a circle, an X, or place a piece. Record the exact mass in Table B. In this lab this was analyzed in multiple collision situations. in the water. Inquiry Lab Kinetic Energy and Motion Read the entire activity on pages 180 and 181 of the textbook. However, the analysis of kinetic energies proved that kinetic energy is not always conserved. Find the values of (a) I2I_2I2, (b) I3I_3I3, and (c) R3R_3R3. The values of the velocities were shown on the Logger Proprogram. Place the strainer and lead in the hot water bath. e. Turn on your heat lamp(s). a. Repeat Step 3a for the 200 g samples. in Table B. You'll need to measure the time from when the ball leaves your hand to exactly when it hits the ground. This would force the carts to stick together after collision. : an American History - Chapters 1-5 summaries; Analysis of meaning and relevance of History from the millennial point of view; Newest. . rate of fall of an object was determined by its weight held that matter was constructed out. The analysis of these values showed that momentum is conserved in all collisions. information about whether it This button released the plunger, and propelled both carts down the track in opposite directions. We used the equation Y=mx+b, in order to compare the velocity of each trial by comparing the slope and the y-intercept. Explore the relationship between mass, speed, and kinetic energy using a laboratory Hypothesis #1 If the mass of an object increases, then its kinetic . Energy can be converted from one form to another (potential energy can be converted to kinetic energy) but the total energy within the domain remains fixed. Record this in your notebook. Introduction When law enforcement officials investigate car crashes (see Figure L13.1), it can sometimes be difficult to determine who is at fault and what laws were broken, especially when there is no footage of the crash. Kinetic Energy Lab Report Edgenuity Answers. This would give the velocity of each cart. E. PART II: Examining the Effect of Material Type on Thermal Energy Transfer and Specific Heat PDF Lab Activity: Heat, Temperature and Conduction To determine whether the height at which a marble is dropped affect the size of the crater. You are never to simply list answers to considerations. The analysis of the results of this experiment shows that momentum was conserved in all types of collisions. If the cart maintains at a constant speed, then the cart will have an increase in acceleration. Once you have created your file (s) and are Q&A A rescue diver of mass 89 kg jumps from a hovering helicopter into the ocean 20 meters below. Lab: Physical and Chemical Changes Assignment: Lab Report Active HELP When the standard cart reached the plunger cart they collided, stuck together, and continued down the track with a new velocity.

Collisions occur when two or more objects collide, and can be either elastic, or inelastic. Record your time in your data table in seconds. You wouldn't be wrong, but every object, moving or stationary, has energy. 5. We can say that one form of energy (potential energy) is converted in another form of energy (kinetic energy). a Potential energy d Chemical energy e Electrical energy energy stored in a bicycle at the top of a hill the heat released by a steaming bag of popcorn the bonds between the protons of a. endobj 6. c. Observe the increase in temperature every 20 seconds for 3 minutes, or until the bundle calorimeter into a beaker or other secondary container to prevent wobbling. In this lab two carts will undergo elastic collisions, inelastic collisions, and explosions on a Vernier Dynamic Track. energy that spontaneously passes between a system and its surroundings in some way other than through work or the transfer of matter. 124 lessons. These values were recorded, and the procedure was repeated two more times for a total of three readings. (a) The balls will not move because K1=K2K_1=K_2K1=K2 before the collision. I have a template, that is simple and clear to understand. ANSWER KEY . 2 0 obj ***Repeat steps 2-4 for each of the following: 5 mL of oil and 2 g each of cornstarch, sodium chloride, and sodium bicarbonate. Considerations: These are not questions to be answered as a separate part of the lab report. The sums of the multiples of each balls mass and velocity before and after the collision should be equal as is shown in the above equation for the conservation of momentum. Assume that the velocity of the soda bottle falling from a height of 0.8 m will, be 4 m/s. At the level of reference the ____________ is considered equal. What was determined to be true was that the structure that contained the right configuration in producing a high amount of force proved to have the greater amount of displacement of the marshmallow. So, now that it's made, I hope it helps a lot of people to get work done especially if they're really behind! In inelastic collisions kinetic energy was not conserved because the value of the ratio of initial and final kinetic energy was not close to one. Because momentum is conserved we can state that the final momentum of a system is equal to the initial momentum of a system in the following equation. If there is a difference, distinguish between what happens . Using your data in Table B, calculate Twater and Tmetal , using Teq and Ti for each metal Open Edgenuity and enter the purchase key. This friction converts some of the energy of the ball into heat, making the value measured for KE less than expected. 1. This button released the plunger, and propelled both carts down the track in opposite directions. This proves that momentum is conserved in collisions.
