Collision

The collision theory states that, for a reaction to occur, particles must collide with the correct orientation with sufficient orientation for a reaction to occur (Compound Chem, 2016). This minimum energy with which molecules must be moving in order for a collision to result in a chemical reaction is known as the activation energy (Boundless Chemistry, 2015). This activation energy barrier must be crossed before reactants are converted to products. The activation complex is a temporary structure of particles, with the ability to become reactants or products (F. Senese, 2010). The collision theory helps explain why some chemical reactions proceed slowly, whilst others fast. Concentration, temperature, pressure, and catalysts are factors which modify the rate of a reaction (CDLI, 2007). These external stresses ultimately increase the number of collisions within the system, therefore increasing the reaction rate. However a catalyst provides an alternative route for the reaction, with lower activation energy. This means that particle collisions need less kinetic energy in order for a reaction to occur, in turn increasing the rate of the reaction (Boundless Chemistry,…

When the collision took place, Carl Young’s van collided with Mary’s Volkswagen in which she was pushed into the intersection and Young’s van followed close behind. This collision is classified as a perfectly inelastic collision. This is a perfectly inelastic because this collision is defined as when two objects “ stick together after the collision, meaning it follows in the same direction (Perfectly Inelastic Collisions). Other than the speeds and velocities and all of the calculations of this…

if one object loses momentum the other object must gain an equal amount of momentum. An isolated system is one which the only forces are between the bodies that are colliding or exploding, no outside forces must be acting. (M.Mann, 2013) Investigative Question: Is momentum conserved during the collision of a brick and a trolley? Hypothesis: The momentum of the trolley before the collision will be equal to the…

and should not be doing. If necessary, why don't you write down the points that are important following a collision, place it in your glove box, so you have it with you should you be an unlucky victim of another driver on the road? The most important element when you stop your vehicle after a collision is never to admit fault, even if you think it may be your fault. This is so important. In some instances you may be completely innocent and the other vehicle jumped a red traffic light, leaving…

late 1400s, the contact between the Europeans and the Native Americans has claimed to shape the time period into an era called the Collision of Cultures. This time period experienced drastic changes amongst these two groups, which primarily were not supposed to be as life changing. Everyone in America and Europe were completely unaware of the existence of each other—much less aware of how to interact and get along with one other first hand. The Collision of Cultures seemed to be inevitable while…

When involved in a collision, you as a driver have several important responsibilities. To begin, you must stop immediately at the scene of the accident; if you hit and run you can be penalized and even get your license revoked for up to a year. If serious enough, you can recieve jail time up to a year, a fine of up to $2,500, or both. After stopping and observing the scene, a person should search for and help anyone who may be injured or in need of assistance. Avoid moving anyone who may be…

Major characters can find themselves in collisions with forces beyond their control, and in many cases their responses to the collision can be described as morally questionable. To what extent do you agree with this statement? Lauren Acey In the text “Othello” by William Shakespeare major characters did find themselves in collisions beyond their control. Othello’s response to the creature of jealousy was at times morally questionable. Othello faced a collision with jealousy as he failed to…

It Was Just An Accident Moments, life is full of them, your first kiss, drivers licence, graduate high school , maybe even college, getting married, and maybe even having kids. There are many important moments to a man's life but we all have that one moment that stands out ,the outlier. The one that stands out the most to me is my father's car collision. That day changed me for the rest of my life. When i was a kid about 6-7 my father was in a car collision. He got pretty beat up in the…

Head on Collisions: Head on collisions are the worst kind of accidents because both drivers are affected greatly because of the force sustained from two vehicles hitting each other from opposite directions. (Head-On-Collisions-The Most Dangerous Type Of Accident, 2016) Even though only about two percent of accidents are head on these accidents account for over ten percent of fatalities due to accidents. (Head-On-Collisions-The Most Dangerous Type Of Accident, 2016) Injuries from these…
