base the entirety of their knowledge on. This theory also directly contradicts Julius Robert Mayers’ Law of Conservation of Energy and Antoine Lavoisier’s Law of Conservation of Mass. It provides a history to where the elements of our periodic table came from, and possibly a date to when the universe began. P1 - How does it contradict the Law of Conservation of Mass and the Law of Conservation of Energy? Carl Sagan quoted that “we are made of starstuff”, but what does this really mean? Sagan
halfway down the incline will cause the sphere’s potential energy to be: a. 12 J c. 3.0 J b. 6.0 J d. 0 J 3. Which mass has the greatest potential energy with respect to the floor? a. 2-kg mass 10 m above the floor c. 50-kg mass resting on the floor b. 6-kg mass 5 m above the floor d. 10-kg mass 2 m above the floor
employing uniform linear motion relations, the kinematic equations; 2) using the principles of conservation of energy and momentum. In this paper, we aim to validate the law of conservation of momentum. We do so by comparing results from two experiments conducted with a single ballistic launcher/pendulum apparatus. Hypothesis: The initial velocity of a ballistic pendulum can be determined using the law of conservation of momentum. Momentum
state. The sodium bicarbonate, however, was a white powder, in a solid state. The reaction caused the new substance to bubble and foam, producing a gas. (Table 4) Quantitative Observations from Part 2 - Mass of Sodium Bicarbonate (g) | 1.01 | Mass of Acetic Acid (g) | 14.29 | Mass of Products (g) | 14.88 | Analysis Part 1: The chemical reaction that took place was evidenced by several qualitative observations. The colour of the two original substances was clear, and when combined the
product. The law of conservation of mass states that mass can neither be created nor destroyed. The reaction between the baking soda, the sodium bicarbonate, and the vinegar, the dilute acetic acid, yields carbon dioxide gas, water, and sodium acetate. When the mixture is created in a beaker the carbon dioxide gas that is produced escapes through the large opening. In the plastic bag, however, the carbon dioxide gas should not escape if the bag is completely closed, thereby leaving the mass of the bag
The big ball (larger mass) possessed more mechanical, gravitational potential and kinetic energy than the small ball (see summary table above) whereas the ball with the smaller mass possessed less energy correspondingly (3.9976 > 0.4588, 1.2242 > 0.0428, 6.1853 > 1.2242). This trend was consistent throughout all of the recorded results. This can be justified by the equations of mechanical, gravitational potential and kinetic energy which all include mass meaning a larger mass constitutes to more
FREE FALL AND CONSERVATION OF MECHANICAL ENERGY ABSTRACT Free fall is defined as the ideal falling motion of an object that is subject only to the earth’s gravitational field. To prove the law of conservation of energy, the free fall motion of an object can be represented through 3 different analyses; position of the object vs. time, velocity of the object vs. time, and acceleration of the object vs. time. It is observed in this ball toss experiment, at any point during the free fall period,
consumed. They have the ability to increase the rate of reaction in a chemical reaction. Catalysts achieve this by lowering the amount of energy required for a reaction to take place, which means that it occurs at a quicker rate. Potentially, molecules that would once have taken years to interact, can take seconds with the addition of a catalyst. The overall purpose of a catalyst is to ensure that reactions proceed effectively which is why a range of catalysts are commonly used in many elements
and I2 molecules would not be capable of moving close enough to each other, and a reaction would not occur. Deprived of acid, the reaction of Zn + I2 would have resulted in 2HI(aq) rather than ZnI2 (s), and it wouldn’t have appeared to follow the Law of
problem than aerodynamics. Conservation laws Aerodynamic problems are solved using the conservation laws, or equations derived from the conservation laws. In aerodynamics, three conservation laws are used: 1. Conservation of mass: Matter is not created or destroyed. If a certain mass of fluid enters a volume, it must either exit the volume or increase the mass inside the volume. 2. Conservation of momentum: Also called Newtons' second law of motion. 3. Conservation of energy: Although it can
