Steps. = This button released the plunger, and propelled both carts down the track in opposite directions. We'll use a ball to measure potential energy and kinetic energy and examine how the energy is converted from one form to another as the ball falls from a high place. What buret reading should you record when the liquid level is as shown in Figure 2? in Table A. dumping the sample into the calorimeter. In class we learned about the principles of acceleration, time, and velocity. Even thought Ionic bonds still hold molecules together, they are weaker than covalent. Measure out 500 mL of tap water in the 1 L beaker and bring it to a boil using a hot plate with 300 mL of room temperature, add water to the calorimeter until you read 300 g of Record the exact mass in Table B in the row for aluminum, as this will be the first Once you have created your file(s) and are, An aircraft weighing 18785 N returns to the aircraft carrier and lands. Later, one piece of rock is dropped from different heights and hole made measured. The raw data readings for the elastic collisions are shown below. The hole each rock made is measured for its depth. Amanda has taught high school science for over 10 years. Place the strainer and lead in the hot water bath. At the maximum height h, the object's GPE will be a _______. One atom borrows one or more electrons from another atom. Newton's second law says: Force equals mass times acceleration (F= m x a). 3 0 obj They are hints. You can set your soda bottle on the, balance, and carefully add or remove water as needed to adjust the total. D is a herbivore or a carnivore.

The values of the velocities were shown on the Logger. Trim off the bottom half of three foam cups. Make sure you record the mass in kilograms in your notebook. In physics momentum is always conserved. A mass of gas has a volume of 380cm3380 \mathrm{~cm}^3380cm3 at a pressure of 560mmHg560 \mathrm{~mm} \mathrm{Hg}560mmHg and a temperature of 7C7^{\circ} \mathrm{C}7C. When does the ball have the most kinetic energy? The cue ball strikes the billiards ball and loses velocity after the collision occurs and the billiards ball gains velocity after the collision. Organismic Lab Lab1- Dichotomous Key Introduction A dichotomous key is a series of paired statements or questions that are used to categorize organisms with their similarities in characteristics and or structure. PART I: Examining the Effect of Material and Mass on Thermal Energy Transfer Add water to the cup until the total mass reads 200 g. Repeat This was calculated using the following formula. When you are finished, submit this assignment to your teacher by the due date for full credit. If the mass of an object increases, then its kinetic energy will also increase because, mass and kinetic energy have a directly proportional relationship and have a linear, Independent: mass of the soda bottle (changing amounts of liquid), Measure the length of your wooden board, and divide that in half to mark at, its midpoint. Do this at least five times and take the average. 2 0 obj An object moving with a speed of 67 m/s and has a kinetic energy of 500 J, what is the mass of the object. On the Logger Pro 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. Place the lid on the calorimeter, and insert the thermometer. KE = mv2 2 KE = 500J m = ? Instead, it changes from one form of energy to another. To begin the lab a Vernier Dynamic Track was set up and leveled on a table. The conservation of the energy is happening in the presence of ____________ like gravitational forces or the force in a spring. Two carts, that had already been weighed, were placed in the track. If the compound possesses the qualification of an electrolyte, it can be identified as an ionic compound, seeing as ionic compounds are capable of conducting electricity when dissolved in water. These equations are as follows: The purpose of this lab was to test the relationship between velocity, position and time. On the other hand, the evidence shows that the 12 pound bowling ball in Ball- Mass 2 has the velocity (m/s) of 3.12, the kinetic energy of 23 (J), and the average bowling points of 4 . G. Establish an initial temperature of the metal samples. These sensors were attached to a computer, which was running the Logger Proprogram, through a Vernier computer interface. 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. PDF Half-Life Data-Teacher Answer Key - US EPA at a height of 10 cm from the materials. 6. SOLUTION: Kinetic Energy Student Guide Lab Report - Studypool I've been adding the answer key to my World History and Biology course. Heat Transfer - The movement of thermal energy from one object to another of a different temperature. These values were recorded, and the procedure was repeated five additional times for a total of six readings. You may continue with Part II until it is time to check This includes knowing the displacement, velocity, and acceleration of objects. The purpose of this lab is to test substances and to determine the physical and chemical properties of substances. stream There are four equations that can be used in both one-dimensional kinematics and two-dimensional kinematics. 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). After these values were calculated the ratio of the final kinetic energy to the initial kinetic energy was calculated in order to compare the values. All rights reserved. Additionally the lab taught how to properly work with carts on a Dynamic Track. These sensors were attached to a computer, which was running the Logger, program, through a Vernier computer interface. I'm remaking this, so it'll be more coherent. Typically an ionic bond occurs between one metal and one non-metal ion. Create your account. In elastic collisions the objects that collide do not stick together, and both continue on with new velocities after the collision. 2. The temperature of the metals should have reached the same Suggested Answers 1. The raw data for the explosions is shown below. After these values were calculated the ratio of the final kinetic energy to the initial kinetic energy was calculated in order to compare the values.
