Physics in Roller Coasters There is a lot of Physics in a roller coaster. It contains a lot of potential and kinetic energy‚ and also centripetal force. All of these factors will define how the roller coaster really works. As we all know‚ or some of us know‚ roller coasters doesn’t use engine to operate the ride. It depends on converting potential energy into kinetic energy. Cars will need a certain amount of pull or push to reach a certain peek of the track. Upon reaching the peak‚ the energy

QUALITY ASSURANCE IN OPEN SOURCE SOFTWARE DEVELOPMENT: A SYSTEMATIC LITERATURE REVIEW Abstract Background : A software development methodology was initiated from the concept of sharing the source code. In 1998 it was named as open source software development. Objective : To collect and analyse reported issues on quality assurance in open source software development Method : Based on the guidelines for conducting a Systematic Literature Review(SLR) by Kitchenham. Results : This paper present

An Open Mind to an Open System AN OPEN MIND TO AN OPEN SYSTEM The Open System Theory was initially developed by Ludwig von Bertanlanffy (1956)‚ a biologist‚ but it was immediately applicable across all disciplines. It defines the concept of a system‚ where "all systems are characterized by an assemblage or combination of parts whose relations make them interdependent". As one moves from mechanical to organic and social systems‚ the interactions between parts in the system become more complex

Gabrino‚ Juan Miguel M. ENGPHY1‚ 1. As I observed while riding both the Dodgem and Bump n’ Splash the direction of the force when my friends bumped me was same with the direction where the car of my friends are headed. According to Newton’s second law‚ an object that experiences an unbalance force will accelerate in the direction of the unbalanced force. 2. While riding the wheel of fate while it is continuously moving I felt the greatest acceleration at the bottom of the Ferris wheel

Equations of Motion Worksheet 1. A car moving at a velocity of 25 m/s‚ accelerates at a rate of 6 m/s2. Find its velocity after 3s. 2. An object is dropped from rest. Calculate its velocity after 2.5s if it is dropped: a. On Earth‚ where the acceleration due to gravity is 9.8m/s2. b. On Mars‚ where the acceleration due to gravity is 3.8m/s2. 3. A motorbike is travelling with a velocity of 3m/s. It accelerates at a rate of 9.3m/s for 1.8s. Calculate the distance it travels in this time. 4. A Tesla

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
