INTRODUCTION During collisions involving two bodies‚ equal and opposite forces are set up between them. These impact forces influence the subsequent motion of the bodies. Momentum of the system (consisting of both bodies) is preserved if both bodies are free to move in space. This is because there is no external forces act on the system. The forces acting between the bodies during the small interval of time when they are in contact cause changes in the velocities of each separate body. An

STARWARD ACADEMY WORKSHEET # 2 MOMENTUM DUE: 1. Calculate the momentum of an object if: (a) its mass is 4.0 kg and its velocity is 8.0 ms-1 (b) its mass is 500 kg and its velocity is 3.0 kms-1 (c) a force of 20 N is applied to it for 6.0 s and it moves from rest (d) its mass is 2.0 kg and it falls from rest for 10 s (assuming g = 10 ms-1 or 10 Nkg-1). 2. A car of 1200 kg is pushed along a level road by two men. If they use a force of 800 N and frictional forces acting against

The captains of MV St. Thomas Aquinas and MV Sulpicio Express Siete told conflicting stories about the collision of their ships last week at Lawis Ledge in Talisay‚ Cebu when they were called in by the Special Board of Marine Inquiry (SBMI) yesterday. The SBMI also called in the captain of Trans Asia Nine as the vessel was reportedly present in the accident area prior to the collision on the night of Aug. 16. Captain Reynan Bermejo of St. Thomas Aquinas said he was traversing the inbound lane on

“We came here to serve God and the king‚ and also to get rich.” In “The Collision of Cultures”‚ the authors explain the different perspectives of America. Long before the Columbian era‚ people did inhabit the Americas. Indian tribe settled in Mexico known as the Aztecs and Mayans; Further down‚ in South America‚ the vast Incan empire was located. These tribes were each had their own sophisticated society‚ with its own agriculture and trade. However‚ in North America‚ Native Americans were slightly

*CHEMICAL KINETICS Collision theory and rates of reaction *One of the main considerations when examining chemical reaction is whether it will take place fast enough for it to be useful. *In other words‚ there’s no point carrying out a reaction if it takes 150 years to form the product! *Many chemical reactions occur very quickly. *Studying Reaction Rates *Defined as the change in concentration of reactants of products per unit time. *Units: mol dm¯³ s¯¹ *Rate of Reaction * ‚ the

Culture collisions has been both positive negative to those involved such as Columbus and his run in with the Natives Americans‚ French revolution and the Haitian slaves‚ and African Imperialism. In any culture‚ subculture‚ or family in which belief is valued above thought‚ and self-surrender is valued above self-expression‚ and conformity is valued above integrity‚ those who preserve their self-esteem are likely to be heroic exception. In the culture collisions I learned about most was trying to

Culture collision plays a role in the world everyday in different situations. Culture collision is when two different cultures collide. When a person from a different country and culture move they have to adjust to whatever the culture of the place they moved to is. For example‚ immigrants moving from foreign countries to the United States have to change their whole life style to fit in with the culture of the U.S. They would have to get used to the life style of being an American such as learning

Collisions may involve many different qualities but momentum is a main aspect of a collision. There are three main types of collisions: elastic collisions‚ inelastic collisions‚ and completely inelastic collisions. All collisions involve momentum because momentum is conserved in all collisions. Momentum is also known as mass in motion and a vector. Momentum equals mass times velocity‚ which is found during a collision. Momentum is an important part during a collision because it determines the outcome

Collision Theory The theory proposes that molecules must collide in a particular way with a certain amount of energy to ultimately form a new product. This is because only a select portion of molecules during a reaction have enough energy and the correct orientation to break any existing bonds to form new ones at the moment of impact with other reactants. The very minimum amount of energy needed for this process to occur is referred to as activation energy. Collision theory explains why reaction

Experiment 4 Inelastic Collisions‚ Conservation of Momentum and Non Conservation of Kinetic Energy Preparation Prepare for this week’s experiment by studying Newton’s Laws‚ linear momentum‚ and kinetic energy. Principles In this experiment you will study a collision where a moving object strikes and sticks to an initially motionless object. When the colliding objects stick together the collision is said to be completely inelastic. The net momentum of the system should not change‚ but the
