One you have found this distance, focus more carefully on this position so that you can take a measurement from the edge of the table to the position where the duck initially contacted the ground. An ionic bond is a type of chemical bond that occurs when one atom loses an electron to form a positive ion and the other atom gains an electron to form a negative ion, which then result in attraction. When these ion separate, its called dissociation. We know that the law of conservation of energy says that energy can never be created or destroyed, so what happened? 2. This would force the carts to stick together after collision. As the height _________ the GPE will decrease while its kinetic energy increases. The purpose of this lab is to test substances and to determine the physical and chemical properties of substances. The Just Drop It investigation was very informative and taught important lessons.

I made this because I was having to do all the research and I would've loved it, if someone had already done this. The raw data readings for the elastic collisions are shown below. 3. m 1 < m 2 If m 1 < m 2, then v 1f < 0, which is to say that object 1 reverses direction. complete other steps of the lab. Acceleration is an objects increase in velocity. The volume is determined by measuring with a ruler and by water displacement. The Photogate sensors were used to measure the velocity of each cart as it moved from the explosion site. This will serve as a backstop for launching the duck. A 50 kg ball traveling at 20 m/s would have kinetic energy. In this condition the two carts were placed together in the center if the Photogate Sensors. In the presence of nonconservative forces (like __________), the total mechanical energy is not conserved. 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. For observation 2 add. Place an empty trimmed cup on the mass 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.
