Rebecca Nov. 2013 Kyle‚ Mat‚ Alex Lab M7 Conservation of Momentum Abstract: This experiment involved the use of gliders on an air track which nearly isolates the colliding system from external forces to create low friction totally elastic and inelastic collisions. Seven different collisions were made‚ four elastic and three inelastic. The collisions consisted of only two gliders with varying masses and speeds. Each glider cart was equipped with a flag‚ and its passage through a photogate

The 1920’s was a period of groundbreaking and progressive change in the United States. Women’s roles in society changed and the economy experienced great growth as a result of innovative ideas and entrepreneurs. However‚ at the same time it was an era of intolerance and conservative ideas like prohibition. Women’s roles in society changed during the 1920’s. As a direct result of the war‚ the number of women in the workforce rose and they moved into better‚ higher-paying jobs. After the Nineteenth

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

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

Reform in 1900 – 1920 The reform in the early 1900’s was a change that desperately needed to happen. From the meat industries exposure to child labor reform was no doubt required. Progressive era reformers and the federal government were two large advocates for reform‚ they made a huge impact in health and policy but the federal government still faced criticism. The push for reform on the health standards was definitely one of the biggest impacts in 1900-1920. An example being the meat industry

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

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
