These results are shown in the table below. : an American History - Chapters 1-5 summaries; Analysis of meaning and relevance of History from the millennial point of view; Newest. This is because of the law of conservation of momentum. circle one Try to let Then push the duck so it is compressed and is going to launch horizontally . In this experiment, we will collect data on velocity, speed, and time. Because momentum is conserved we can state that the final momentum of a system is equal to the initial momentum of a system in the following equation. The hole each rock made is measured for its depth. They have opposite properties and have the ability to cancel or neutralize each other. This experiment will be exploring, in depth, Newton's second law. This could have caused the velocities to be slower than they should have been because there was a velocity due to the friction. first example, heat energy is transferred from the stove to the pot of water, and the water absorbs the heat energy and will eventually begin to boil. Accuracy is how close the average of the measured values are to the actual value. It can be proven that there were multiple sources of error by the slope of the equation on the Force vs. Acceleration group for this lab. If needed, place the KE = KE = 2500 J 6.
