Lab: Momentum Conservation Abstract This experiment aims to test the law of conservation of momentum by using cart and track system. Procedure 1. Put two carts onto the track. 2. Hit the button on the cart so that they start to move at opposite directions. 3. Find the position where the carts hit the end at the same time. 4. Find the distance that each cart traveled. 5. Repeat step 1-4 with 500g and 1000g weights on one of the carts. Data and Calculation m1m2=x2x1

American progressive era‚ from 1890s to 1920s‚ is believed to be a period of societal awakening. Although‚ there is no particular date that could be mentioned to mark its end‚ yet people believe that it lasted for around 30 years. After the civil war‚ the rapidly developing American economy was facing hundreds of problems due to its structural weaknesses. The capitalist system came under severe criticism because of the prominent flaws in its basic structural composition. The issues like racial segregation

MOMENTUM QUESTIONS 1. Which has greater momentum: a train at rest or a moving skateboard? Since the train is not moving‚ it has zero momentum. The skateboard‚ as long as it has some speed‚ will have more momentum‚ since p = m*v. 2. What are the ways to increase impulse? Impulse depends on the magnitude of the applied external force and the time that the force acts on the system. By increasing either of those‚ impulse on a system will be increased‚ and the system’s momentum will change accordingly

Angular momentum and its properties 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.<br><br>Torque is the angular "version" of force. The units for torque are

Momentum‚ p‚ is the product of an object’s mass (kg) and its velocity (m/s). The unit for momentum‚ p‚ is kg·m/s. During a collision objects transfer momentum to each other‚ resulting in different motions than before the collision. In this activity you will study

The Progressive Era‚ which lasted from 1900 to 1918‚ was a time in which the American government and its people aimed to improve their economic status and to correct injustices of their country. Here are the ten leading reform movements: 1. Civil Rights After the Civil War‚ some would have expected that racism would have stopped but unfortunately‚ that didn’t happened. Racism still existed in the American society in the stated era therefore civil rights organizations‚ most made for African-Americans

growth and drastic cultural reform in the United States. Mass consumerism dictated an American’s everyday life with the emergence of buying goods‚ such as the Model T and radio‚ on credit. The once modest maidens now proclaimed their new freedom as "flappers" in bobbed hair and provocative clothing. Jazz became the soundtrack to the young artists and writers of the Lost Generation. One of the oddities of this time of progressive reform‚ however‚ was prohibition. In 1920‚ the United States passed the

Laboratory V: Conservation of Momentum Problem #1: Perfectly Inelastic Collisions John Greavu April 17‚ 2013 Physics 1301W‚ Professor: Evan Frodermann‚ TA: Mark Pepin Abstract A cart was given an initial velocity toward another stationary cart down a track. The initial velocity of the first cart as well as the masses of both carts was varied throughout multiple trials. Velcro placed on the ends of the carts caused the cars to stick together after colliding. Videos of the collision and the seconds
