intervals the mass will be recorded. The manipulation of the independent variable‚ in this case the concentration of hydrochloric acid (HCl) relies on the collision theory of kinetics. The collision theory stipulates that in order for a chemical reaction to transpire‚ the reactant particles must possess sufficient energy and the correct collision geometry. There are five main factors which affect the rate of reaction‚ including temperature‚ concentration‚ particle size‚ pressure and the presence of

box. When assigned the project of creating a device to secure eggs in a collision with a pendulum at increasing velocities‚ I immediately thought of a car crash. Cars must be built that so that they will protect the passengers during any type of collision‚ like my project must be built to protect the eggs. Upon this thinking I decided to design my egg crash project like the design of a car. I would create an inelastic collision between the pendulum and project‚ meaning

accordance with collision theory. Introduction The reaction rate or rate of reaction for a reactant or product in any given reaction can be defined as the speed with which a reaction occurs. For example‚ the oxidation of iron (rusting) is a slow reaction which can take many years‚ but explosive combustion‚ such as the ignition of fuel‚ can take as little as fractions of a second to complete. Dealing closely with reaction rates is collision theory. First proposed in 1916‚ collision theory describes

Sector Critical Incident Team (CIT) was notified of a vehicle collision‚ which involved an unmarked K-9 Border Patrol vehicle K95266 (herein referred to as FED-1) and a civilian vehicle (herein referred to as VEH-1). The collision occurred in the Yuma Border Patrol station’s area of responsibility‚ near the intersection of east 32nd Street and Windsor Avenue. SCENE LOCATION: From the Yuma Sector Headquarters‚ the area of the collision can be located by traveling east on 40th Street‚ then north on

involved in automobile collisions and how physics can and has been used to prevent injuries in collisions. The aspects that are primarily being dealt with are things such as seatbelts‚ airbags‚ headrests and all. SEAT BELT The job of the seatbelt is to hold the passenger in place so the passenger is almost part of the car which prevents the passenger from flying forward as the car stops abruptly in the case of a collision. When a car stops suddenly due to a collision with another object such

Driving Being a safe and responsible driver takes a combination of knowledge‚ skill and attitude. To begin‚ you must know the traffic laws and driving practices that help traffic move safely. Breaking these "rules of the road" is the major cause of collisions. Traffic laws are made by federal‚ provincial and municipal governments‚ and police from each level can enforce them. If you break a traffic law‚ you may be fined‚ sent to jail or lose your driver’s licence. If you get caught driving while your

contain several different types of safety features. These numerous safety features all have their own significance to the driver‚ as well as to the passengers. The purpose of this report is to show and express how physics is involved in automobile collisions and similarly how it is used to prevent injuries during accidents. Isaac Newton’s three laws of motion are used to describe the purpose of the three main safety features that cars are obliged to consist of; seatbelts‚ airbags‚ headrests‚ those of

FRICTION Friction is necessary for walking due to the following reason‚ As per Newton’s third law of motion‚ (every action has an equal and opposite reaction) we can walk if and only if the ground we are walking on push our feet back with a force. Now‚ as per the third law the ground would definitely push our feet back but if we are walking on a perfectly smooth ground which has no friction our force would simply cancel out the force reverted by the ground and we would fall. If there was no

hypothesis is based on the collision theory. The collision theory states that for a chemical reaction to occur‚ there is a minimum amount of energy that must be provided by the colliding particles in order to break or form new bonds with other particles. When the bonds are broken this is called a successful collision. If the minimum amount of energy (also known as activation energy) is not provided‚ the particles will simply bounce off each other causing an unsuccessful collision. Applying this theory
