was poured into the small test tube until it was approximately half full. The test tube was placed inside the Erlenmeyer flask, and sealed with a rubber stopper – the solutions were not mixed. The mass of flask, stopper and contents were determined by being placed and weighed on a small scale. The mass determined was then recorded in another table. The Erlenmeyer flask was tipped so the previously separate solutions were allowed to mix, and the new mixture was again weighed and recorded in the second
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,
energies combined are lower than the activation energy without the presence of a catalyst. (4College, n.d.) 1.7 Conservation of Mass “The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations.” (Boundless, n.d.) The law implies that the mass of the products will always be equal to the mass of the reactants. With this theory in mind, a chemical reaction can be described as the rearrangement of atoms and
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 Conservation of Mass. The experiment was performed in order to determine if this law is truly followed. During the experiment, all weight measurements were performed on a balance pan. To ensure accurate measurements, each test tube was weighed before and after addition of any substance with
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
were devised over time by many of the great minds in physics. Newton and Kepler were probably the two biggest factors in the evolution of angular momentum. Angular momentum is the force which a moving body, following a curved path, has because of its mass and motion. Angular momentum is possessed by rotating objects. Understanding torque is the first step to understanding angular momentum.Torque is the angular "version" of force. The units for torque are in Newton-meters. Torque is observed when
Momentum Project Angular Momentum: The Physics of Spinning Although many know the physics of “spinning”, not many people are aware of how angular momentum explains the physics of rotation. Now it is true that all objects have a momentum, a product of mass and velocity. But similarly, the inertia of rotating objects is called angular momentum. When a direction is given to a rotational speed, we call this rotational velocity, and its vector is rotational speed. Therefore, angular momentum is the product
Introduction: For the conservation of energy lab three experiments were performed. Terrestrial Gravitation Acceleration, First Law of Thermodynamics and Centripetal Acceleration vs. First Law of Thermodynamics. Each of the experiments demonstrated the importance of the first law of thermodynamic and how its present on our daily lives. Therefore, reinforcing the importance of thermodynamics concepts and their role in our society. Objectives: Experiment A: Terrestrial Gravitational Acceleration
