Since it's still and high up, the object only has GPE. Apply the properties of kinetic and potential energy. This lab taught how to do calculations for multiple situations that involve momentum. Simply put, his law describes the relationship between the mass of an object, the acceleration of an object, and the force needed to move it. 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. 4 times more 4 times less The energy of a moving object is called kinetic energy. This increase can be explained by the fact that the potential energy of the spring, that was holding the plunger back, was transferred to kinetic energy as the plunger was released. Energy is never created or destroyed, only converted between forms - this is known as the law of conservation of energy. These sensors were attached to a computer, which was running the Logger, program, through a Vernier computer interface. A rod was used to push down the button on top of the plunger cart. Record the exact mass in Table B. Upon graphing the data, the best fit line was identified in order to find the formula of the function.

Next, we need to do some calculations to find GPE and KE. Kinetic energy (KE), the energy of movement, and gravitational potential energy (GPE), or stored energy due to height. 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). What is its volume at s.t.p.? at a height of 10 cm from the materials. Also make a hypothesis about which type of material will heat up the fastest. It goes from 414.2 kilometers per hour (kph) to 0 kph in 2.8 seconds. Repeat steps 5 and 6 for KNO3. 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. After the time has elapsed, record the actual elapsed time in the Tfinal column in Table A. Draw a circle, an X, or place a piece. The values of the momentum ratio are very close to one which indicates that the momentum is conserved in the experiment. If needed, place the The conservation of the energy is happening in the presence of ____________ like gravitational forces or the force in a spring. When the standard cart reached the plunger cart they collided, stuck together, and continued down the track with a new velocity. A practices intracellular or extracellular digestion. fastest. On the Logger Pro program the reading from the first sensor was the initial velocity of the standard cart, and the reading from the second sensor was the final velocity of both carts. The percent difference was calculated using the following formula. Acids and bases are carefully regulated in the body by the lungs, blood, and kidneys through equilibrium processes. Record your time in your data table in seconds. 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. a. 2. This cart also had a rod to assist in readings. The initial velocity of the standard cart and the final velocity of both carts, moving together as one, were measured using the Photogate sensors. = program was set up so that it would collect the Gate Time from each Photogate sensor. the total energy in the system will not change.
