When does the ball have the most kinetic energy? 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. The conservation of momentum is a very important concept in physics. Record this in your notebook. Since it's still and high up, the object only has GPE. at a height of 10 cm from the materials. Place the pH probe in the beaker and record the pH in the data table. - g is gravity (not to be associated with the acceleration due to gravity because g is a scalar) Edgenuity Answer Key! in comparison to white Americans? <>/ExtGState<>/XObject<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> Get your timer ready and prepare to drop the ball.

Overall the total energy (kinetic plus potential) is __________. Newton's second law says: Force equals mass times acceleration (F= m x a). b. Swirl the thermometer slightly, and confirm that the thermometer is well within the water. Think of total energy like a pizza. these samples. There were no controlled variables used in this experiment. dumping the sample into the calorimeter. Ionic bonds form their bond when opposite charged ions in a chemical compound have an electrostatic attraction. 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. A 50 kg person falling at 10 m/s would have kinetic energy. However, the analysis of kinetic energies proved that kinetic energy is not always conserved. These values were recorded, and the procedure was repeated five additional times for a total of six readings. Also! This is known as the conservation of energy. To begin the lab a Vernier Dynamic Track was set up and leveled on a table. 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. The values of the momentum ratio are very close to one which indicates that the momentum is conserved in the experiment.

Data: m = kg Fave = N x (m )v /s Wo rk JKE % Dif enc Scoring Rubric: E6. Overall the total energy (_____________) is conserved. kinetic energy to object 2. Even thought Ionic bonds still hold molecules together, they are weaker than covalent. These values were recorded, and the procedure was repeated two additional times for a total of three readings. Measure the mass of your ball on the balance. Mark the board at 7.5 cm from each end. . Privacy Policy. We can monitor the rate at which a chemical decomposes or the rate at which a chemical substance appears. Each chemical compounds has a certain percentage of ionic character in its bonds and the remaining percentage as covalent bonds. Final Lab Report: Solar Cookin' - Suffolk University
