This will teach how to do momentum calculations for a variety of different situations where momentum is conserved - calculations that will illustrate the nature of momentum, and the fact that momentum is in fact conserved. Whenever an object moves, some energy is converted to heat through friction. This taught the very important concept of the conservation of momentum. 3 0 obj What was determined to be true was that the structure that contained the right configuration in producing a high amount of force proved to have the greater amount of displacement of the marshmallow. Energy is never created or destroyed, only converted between forms - this is known as the law of conservation of energy. 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. They then continue on together with one final velocity. (2015,[online]). Use tongs to carefully place the sample in the hot water bath. Explain your reasoning: Which samples will heat up faster? increasing). For observation 1 and 2, pour 1 cup of water into a pan and place on stove on high heat.

What was determined to be true was that the potential energy was larger than the kinetic. In physics momentum is always conserved. What are the units for kinetic energy? When collisions occur, two properties of the colliding bodies are changed or transferred: their Energy and Momentum. hd We used the equation Y=mx+b, in order to compare the velocity of each trial by comparing the slope and the y-intercept. (d) We cannot predict how the balls will move after the collision. Dm is preferable! b) Swirl the thermometer slightly, and confirm that the thermometer is well within the water. kinetic energy lab questions. 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. An example of an elastic collision is a cue ball striking a billiards ball initially at rest. CLEANUP : Leave the test tube with wax stuck in it in the lab station. Dry Sand Within some problem domain, the amount of energy remains constant and energy is neither created nor destroyed. If you measure it in grams, simply divide the number by 1000 to get kilograms. So why would KE and GPE be different? The standard cart moved to a velocity of zero and was still. Aqueous solutions of ionic substances will be experimented with in this Ionic Reactions lab.
