Quantitative Conservation of Momentum Name: ______________________________________ 1. Kim holds a 2.0 kg air rifle loosely and fires a bullet of mass 1.0 g. The muzzle velocity of the bullet is 150 m/s. Find the recoil speed of the gun. Momentum conservation equation: Recoil speed =________________ 2. If the girl in the previous question holds the gun tightly against her body‚ the recoil speed is less. Calculate the new recoil speed for the 48 kg girl. Momentum conservation equation:

Impulse and Momentum Lab Formal Lab Write Up Content Guide ( /3) Abstract : The abstract should explicitly state what law you are trying to show. State the three quantities that you are calculating and what you are hoping to show (what does the law say?). Give a brief explanation of the results. ( /15) Background : The topics included in the background should contain‚ but are not limited to: what is the definition of momentum and how is it calculated what are the differences and similarities between momentum and energy

Conservation of Energy Lab Honors Physics December 9‚ 2014 Date Performed: December 5‚2014 Instructor: Mrs. Kelly I. Objective: Calculate the speed of the Bunny on release from the table II. Procedure: 1. Gather All Materials 2. Place the bunny turned in on itself on the ground (this enables the toy to launch itself upward by suction; elastic and potential energy). Do so 5 times 3. Measure the height traveled by the stopper using a meter stick per each trial. 4. Using the measurements

The Law of Conservation states that mass can neither be created or destroyed. There are two types of changes that can happen‚ a physical change is when the reaction can be reversed and all reactants are separated. A chemical change is when the reaction changes the reactants and creates a brand new substances that can’t be reversed. Antoine Lavoisier had the main contribution to The Law of Conservation. He wrote a textbook in 1789 on chemistry in it he introduced the Law of Conservation. He founded

The law of conservation of momentum states that momentum can neither be created nor destroyed; the total momentum of any closed system must remain the same. Momentum is mass times velocity. Thus‚ a ten pound object moving at 5 meters per second has the same momentum as a 2 pound object moving at 25 meters per second (for example). In order to alter the motion of one object‚ you have to transfer the momentum to another object. Now‚ this principle is not intuitively obvious‚ because we are constantly

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‚

What is momentum? Momentum of a body is defined as the mass multiplied by the velocity of this object. Momentum= m x v Momentum and Newton’s second law of motion: The resultant force is proportional to the change in momentum per a second. We know that force = mass x acceleration. So F (mv-mu)/t F m (v-u)/t = ma so F=kma Momentum is a vector quantity: Momentum has a direction as well as a magnitude Momentum and Newton’s first law of motion: An object remains at

Marble-lous Momentum Question: What happens to momentum when one marble collides with other marbles? Hypothesis: If a marble collides with increasingly more marbles‚ then the momentum will be transferred more slowly to the final marble‚ because momentum is conserved through an inelastic collision‚ but a longer distance will have be traveled by the kinetic energy. Independent Variable: The number of marbles. Dependent Variable: The momentum of the first marble and final marble. Control Variables:
