A rescue diver of mass 89 kg jumps from a hovering helicopter into the ocean 20 meters below. The fact that the kinetic energy ratio was very far from one shows that the kinetic energy is not conserved in inelastic collisions. The values of the velocities were shown on the Logger Proprogram. Place the pH probe in the beaker and record the pH in the data table. These sensors were attached to a computer, which was running the Logger, program, through a Vernier computer interface. f. Make a hypothesis about which set of sample mass, the 200 g or 100 g, will heat up the Precision is the closeness of repeated measurements. There are four equations that can be used in both one-dimensional kinematics and two-dimensional kinematics. Try to let When the standard cart reached the plunger cart they collided, but did not stick together, and the plunger cart moved down the track. The first condition tested was elastic collisions. e. Measure out approximately 50 g of lead pellets, record the exact mass in Table B, and A practices intracellular or extracellular digestion. 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. 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. The experiment was executed by dropping three different balls of different masses at 100, 75, 50, and 25 centimeters. D is a herbivore or a carnivore. Lab #6 - Work-Kinetic Energy Theorem Therefore, if the work done by a particular force appears not to be equal to the change in kinetic energy of the object, then the system should by analyzed for possible work (positive or negative) done by other forces. This was calculated using the following formula. Vocabulary Words . We can say that one form of energy (potential energy) is converted in another form of energy (kinetic energy). The fact that the kinetic energy ratio was very far from one shows that the kinetic energy is not conserved in explosions. KE = mv2 2 KE = 500J m = ? The word dichotomous comes from two Greek words that translate to "divided in two parts. If you do not have . Click the Get form key to open the document and move to editing. Pour out some of the water from your soda bottle to adjust the total mass of, water and bottle to 0.125 kg (125 g). As well as identify how accelerations affects an object's velocity and time. The final condition tested was explosions. b. Swirl the thermometer slightly, and confirm that the thermometer is well within the water. complete other steps of the lab. Lay the board on its midpoint across the 2 diameter cylinder. Think about what you already know about energy. Lab Handout Lab 13. 1. Amanda has taught high school science for over 10 years. The standard cart was pushed towards the plunger cart, which was at rest. hd 498 0 obj <>stream Remove the three cups that have samples of 100 g. Stir each sample gently to mix them, Kinetic Energy Lab Report Speed, height, and mass do affect kinetic energy. At the maximum height, __, the object's GPE will be a maximum. Dry sand 200 19 40 21.
