The major finding was the return bounce height depended the most on the balls mass and from where it was dropped. The Great Depression and the New Deal How did the New Deal affect minorities in the United States (African Americans, Hispanics, etc.) Step 2: Note State and Appearance. These sensors were attached to a computer, which was running the Logger, program, through a Vernier computer interface. Overall the __________ (kinetic plus potential) is conserved. As the data is representative of a graphical parabola, a parabolic function was utilized to be the best fit trendline. e. Turn on your heat lamp(s). 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 (_________). 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. 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. Textbook questions 4 and 5 of "Practice Problems," p. 179 Record an initial temperature for each type of material A 50 kg person falling at 10 m/s would have kinetic energy. @W program.

Close the lid snugly and make sure the thermometer is immersed in Table A. Not because your TA says to do so, but because it adds depth to your discussion. Record this velocity for each mass in Table A, and use it to calculate, the predicted kinetic energy of the soda bottle for the masses using the, Review the following relationship for mass and volume of water: 1mL = 0.001. kg; this means that 200mL of water has a mass of .2kg. What are the units for potential energy? for the other two cups, filling one with 200 g of wet sand and one with 200 g of dry sand. When these ion separate, its called dissociation. A rod was used to push down the button on top of the plunger cart. Assume that the velocity of the soda bottle falling from a height of 0.8 m will, be 4 m/s. In physics momentum is always conserved. Mark the board at 7.5 cm from each end. At the ___________ h, the object's GPE will be a maximum. If you have access to a supervised laboratory, do Part A. The carts were placed on the track so that the Velcro side of each cart was facing the other. PDF Lab Handout Lab 17. Rate of Energy Transfer - NSTA e. Remove the steel wire sample and empty the calorimeter. Two carts, that had already been weighed, were placed in the track. e. Measure out approximately 50 g of lead pellets, record the exact mass in Table B, and At the level of reference the ____________ is considered equal. In this condition the two carts were placed together in the center if the Photogate Sensors. 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. Place an empty trimmed cup on the mass L. Additionally, the lab taught how to complete momentum calculations, and the law of conservation of momentum.

PDF Kinetic Energy Practice Problems - MS BOURBONNAIS TEACHING Practice dropping the soda bottle so that the bean bag pops up straight and, can have its height measure with the meter sticks. If this was added in to the momentum equation the ration of the final over the initial momentum would likely be much closer to one. You'll be measuring the GPE of a ball 4 meters off of the ground and comparing it to the measured KE right before it hits the ground. Whenever an object moves, some energy is converted to heat through friction. 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. 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.
