Visit EdgePlus+ for a purchase key. Understanding of DG =G 2-G 1, the driving force A thermodynamically favorable reaction or process means DG < 0, that's to say, highly driven! 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. The word dichotomous comes from two Greek words that translate to "divided in two parts. Typically an ionic bond occurs between one metal and one non-metal ion. Now find KE. Total score: ____ of 27 points (Score for Question 1: ___ of 3 points) 1. They were joined together by the Velcro, and the plunger was pushed into the plunger cart. 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). These sources of error include human error such as not keeping the acceleration constant, changing the force placed on the van, and by starting or stopping the timer late. Kinetic factor refers to DGa, activation energy; while the thermodynamic factor refers to DG =G 2-G 1, the driving force. So, multiply your value for height, the mass of the ball, and 10m/s2 to get GPE. Think of total energy like a pizza. an object in motion Kinetic object We traded experiments and materials with another group, so each group got a chance to watch an unbiased group perform their experiment. If your time is greater than it's supposed to be, your results won't make sense. or other heating source. A 50 kg ball traveling at 20 m/s would have kinetic energy. Place the lid on the calorimeter, and insert the thermometer. I'm not able to just leave it out in the public since Reddit will take it down because of copyright, lol. 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. This button released the plunger, and propelled both carts down the track in opposite directions. This is based on the equation .5mv^2=.5kx^2, where m is the mass of the duck, v is the velocity of the duck in the air, k is the spring constant of the spring in the base of the duck, and x is the displacement that the spring is compressed. Why or why not? - Facts, Addiction & Withdrawal Symptoms, What Is Zinc? The cue ball strikes the billiards ball and loses velocity after the collision occurs and the billiards ball gains velocity after the collision. This would give the velocity of each cart. Steps. Practice dropping the soda bottle so that the bean bag pops up straight and, can have its height measure with the meter sticks. c.
