Total score: ____ of 27 points (Score for Question 1: ___ of 3 points) 1. % then place a thermometer in each cup and observe the readings until they do not climb All objects have momentum, even if it is zero, and momentum cannot be lost. Acceleration is an objects increase in velocity. information about whether it The mass was determined by weighing the spheres on the Analytical Scale and Triple Beam Balance Scale. This friction converts some of the energy of the ball into heat, making the value measured for KE less than expected. In this experiment, we will collect data on velocity, speed, and time. Non-metals are stronger than metal and can get electrons easily from the metal. This was a result of miscommunication between group members that proceed to affect why the group had the lowest measurement of displacement. Additionally the lab taught how to properly work with carts on a Dynamic Track. (Read Section 7 -3 for a thorough explanation of the W ork-Kinetic Energy Theorem.) The conservation of the energy is happening in the presence of ____________ like gravitational forces or the force in a spring. << If not, why do you think that happened? Visit EdgePlus+ for a purchase key. Acids and bases are carefully regulated in the body by the lungs, blood, and kidneys through equilibrium processes. The slight discrepancies in the values of initial and final momentum can be explained by some sources of error. The hole each rock made is measured for its depth. Each chemical compounds has a certain percentage of ionic character in its bonds and the remaining percentage as covalent bonds. This button released the plunger, and propelled both carts down the track in opposite directions. At the level of reference the ____________ is considered equal. A 50 kg person falling at 10 m/s would have kinetic energy. The law of conservation of energy is a universal principle that says that the total energy of a system always remains constant. The first condition tested was elastic collisions. I would definitely recommend Study.com to my colleagues. c. The three material types should be room temperature, but place a thermometer in each In this condition the two carts were placed together in the center if the Photogate Sensors. the total energy in the system will not change. Assume that the velocity of the soda bottle falling from a height of 0.8 m will, be 4 m/s. dumping the sample into the calorimeter. 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 Proprogram. If that ball rolls down the hill however, all the GPE is converted to KE when it gets to the ground and is moving fast. The hypothesis that if it the ball was dropped from a higher drop points, it would have a greater bounce height was supported. Place an empty trimmed cup on the mass They should start immediately when you drop it and stop it exactly when it hits the ground. A 50 kg ball traveling at 20 m/s would have kinetic energy. Table A: The Effect of Mass or Material Type on Thermal Energy Transfer. All other trademarks and copyrights are the property of their respective owners. Measure the height from which you'll be dropping your tennis ball. The Just Drop It investigation was very informative and taught important lessons. temperature. f. Make a hypothesis about which set of sample mass, the 200 g or 100 g, will heat up the Velocity is how, The purpose of the experiment was to use previous knowledge of velocity yo perform kinetic energy calculations, make calculations of gravitational potential energy, and to determine what affects GPE and KE more. We can monitor the rate at which a chemical decomposes or the rate at which a chemical substance appears. This allows you to get a more accurate answer. Overall the total energy (_____________) is conserved. Additionally, the lab taught how to complete momentum calculations, and the law of conservation of momentum. This proved that momentum is in fact conserved. Kinetic Energy Lab Report Speed, height, and mass do affect kinetic energy. Measure 200 mL of water with the graduated cylinder and transfer it to an.

As usual, you should refer to, 1. The initial velocity of the standard cart and the final velocity of both carts, moving together as one, were measured using the Photogate sensors. 3. Dm is preferable! Try to let /Length 2645 This was done by causing elastic collisions, inelastic collisions, and explosions of carts on a Dynamic Track. kinetic energy lab questions. However, when the group was compared to other groups conducting the same experiment, the displacement of their marshmallow was the shortest. The major finding was the return bounce height depended the most on the balls mass and from where it was dropped. In this lab this was analyzed in multiple collision situations. Since it's still and high up, the object only has GPE. Using your data in Table B, calculate Twater and Tmetal , using Teq and Ti for each metal at a height of 10 cm from the materials. Repeat Steps 68d for the 13 chapters | 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. endobj We interpret the = sign to mean that the gravitational potential energy of the ball before it fell was converted into an exactly . Concluding that in my Game 1 the velocity of the masses of the bowling balls decreased when the bowling balls were heavier and that the kinetic energy was lower as the mass increased in the bowling balls. Execute Energy Forms And Changes Lab Answer Key Pdf within a couple of moments by simply following the guidelines below: Pick the template you will need from our library of legal form samples. calorimeter into a beaker or other secondary container to prevent wobbling. Which answer correctly explains how the balls will move after a totally inelastic collision? program the reading from the first sensor was the initial velocity of the standard cart, and the reading from the second sensor was the final velocity of both carts. Next, we need to do some calculations to find GPE and KE. We can say that one form of energy (potential 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 (kinetic energy). releases or absorbs thermal energy by chemical processes. The first Photogate sensor measured the velocity of the standard cart, and the second Photogate sensor measured the velocity of the plunger cart. In the presence of nonconservative forces (like friction), the total mechanical energy is, In the presence of nonconservative forces (like friction), the total mechanical energy is not conserved.
