the Adler Planetarium located in Chicago and witnessed the exhibits and the show about the “Cosmic Collision”‚ which was a breathtaking tour around the space. The tour to the planetarium was really a wonderful experience in adding more value and flavor to the wide range of knowledge gained in the class‚ and it did really help me in grasping the real world experience. The show “Cosmic Collision”‚ about 20 minutes long and narrated by Robert Redford was a life time experience that portrayed the

Technologies include: • Seatbelts • Airbags • Crumple zones • Traction control All these technologies are in place to help reduce the effects of a collision. Seatbelts are one of the most affective safety implications in place. They first of all stop a person during a collision from dismounting from the seat of the vehicle

Find (a) the combined final speed if they stick together. (b) if the collision is perfectly elastic‚ their individual speeds if the pucks do not stick together. 2. A bullet of mass 10 g has a muzzle velocity of 300 m/s. Find (a) the momentum of the bullet (b) the recoil velocity of the gun if its mass is 2.0 kg. 3.

1. A gas consists of a collection of small particles traveling in straight-line motion and obeying Newton’s Laws. 2. The molecules in a gas occupy no volume (that is‚ they are points). 3. Collisions between molecules are perfectly elastic (that is‚ no energy is gained or lost during the collision). 4. There are no attractive or repulsive forces between the molecules. 5. The average kinetic energy of a molecule is 3kT/2. (T is the absolute temperature and k is the Boltzmann constant

of the average impact force during collisions. For collisions‚ the mass and change in velocity are often readily measured‚ but the force during the collision is not. If the time of collision can be measured‚ then the average force of impact can be calculated. Examples Involving Impulsive Force • Playing football • Playing badminton • Playing tennis • Playing golf • Playing baseball Impulsive force is produced during collision according to the Newton’s Second Law

There are a few factors that affect the rate of reaction: • Concentration - increasing the concentration increases the probability of collision of the reactants. The collision theory‚ the idea that as more collisions occur in a system there will be more combinations of particles bouncing into each other leading to a higher number of collisions in a system‚ meaning that more particle

isolated system‚ if no net external force acts on a system of particles‚ the total linear momentum of the system cannot change. There are two simple types of collisions‚ elastic and inelastic. If the total kinetic energy of the two systems is conserved then the collision is known as elastic. If the kinetic energy is not conserved‚ then the collision is inelastic.

initiate the reaction. It represents the minimum energy needed to form an activated complex during collisions between reactant molecules. In slow reactions‚ the fraction of molecules in the system moving fast enough to form an activated complex when a collision occurs is low so that most collisions do not produce a reaction. However‚ in a fast reaction the fraction is high and therefore‚ collisions produce a reaction. In 1889‚ Svante Arrhenius demonstrated that the rate constant k is related to
