For my third term paper, I plan on discussing collisions and will relate this to my real life experiences, previous knowledge, movies, books, or tv shows, and personal/ career ambitions. As we discussed in class, collision can either occur in one-dimension or two-dimensions. Collision is based off the concept of momentum. Momentum is conserved in any type of collision. Momentum is found by taking an object's mass and multiplying it by its velocity. There are three types of collisions. There is inelastic, perfectly inelastic, and elastic. Inelastic occurs when when the collision does not conserve kinetic energy. An example might be dropping a ball from a certain height and because of inelastic collisions, it won't get as high as the initial spot at which it was dropped. It is the same thing with a perfectly inelastic collision, except the objects will stick together and the the maximum amount of kinetic energy is lost. In an elastic collision, the kinetic energy is conserved. An good example to see is watching pool, when the balls collide, it is elastic because they bounce off of each …show more content…
The collision theory is a theory used to predict the rates of chemical reactions, particularly for gases (The Editors of Encyclopædia Britannica). For the collision theory to work, atoms or molecules have to come together or collide with one another. Not all collisions with result in a chemical change. For chemical change to occur, the lowest required internal energy must equal the activation energy required for this change to occur, or the act of breaking one or more chemical bond. The collision theory in chemistry and collision in physics are closely related. Although in chemistry, we aren't particularly worried about the mass and the velocity of the molecules or atoms like we are in physics. In chemistry, we are more concerned with the rates of chemical reactions caused by this collision of atoms or

faster, i.e., a lot of time they have more energy than they have. So, they collide with more. energy and more frequently. pH of Solution: Water has a pH of 7 at 25°C. As the pH decreases.
Commonly, vehicular collisions are considered a negative occurrence. Dave Eggers hints towards this mindset in his short story Accident. Plotted in the middle of an intersection in 2005, the story commences with the main character driving his automobile through the intersection and striking an older Camaro. The three teenagers in the Camaro are fine, but the main character notices all the damage he has done to their vehicle and he fears an unpleasant encounter with them. Dave Eggers uses irony throughout the situation to illustrate the main character’s relief. The characters’ involvement with the collision emphasizes Egger’s theme that no matter how unfortunate an incident, positivity can result.
Different collisions took place throughout the process of the Rube Goldberg Machine. This included Elastic and Inelastic collisions. An example of an Elastic Collision in our Rube Goldberg Machine is when the car went down the track and collided with another car. Elastic collisions are defined as collisions with conservation or no loss of momentum. This is proven by the first car which transferred its momentum to the second car thus momentum was perfectly conserved. An Inelastic Collision is seen in our project ...
For a reaction to occur, particles must collide. If the collision causes a chemical change it is referred to as a fruitful collision. (Hutchinson Educational Encyclopaedia, 2000) Enzymes increase the rate of exergonic reactions by decreasing the activation energy of the reaction. Exergonic reactions are those in which the free energy of the concluding state is lower than the free energy of the opening state.
The momentum of an egg dropped into a frying pan at shoulder height is going to be the m x v (mass times velocity). This is going to be the same whether you drop the egg into a frying pan, into a bucket of water, or onto a pillow. The impulse in the egg drop report is the force of the egg multiplied by the time. This is when the egg is in contact with the object and the time that it stays their. When the eggs bounced of the pillow we see a greater change in momentum. We see the momentum come to a stop, but the momentum changes directions. The change in momentum is calculated by multiplying force times time.
Some collisions are successful and give a product while others don't. because particles don't have enough energy. Activation energy - The amount of energy needed for the reaction to be. started. I am a naysayer.
If a reactant is a solid, then breaking it up into smaller pieces (but keeping the mass the same) will increase its surface area. If there is a larger surface area the reacting particles will have more of an area to react with, therefore there will be more collisions. 4. A catalyst works by giving the reacting particles something to stick to where they can collide with each other, because they are all attracted to the catalyst there are going to be more collisions. A catalyst does not get used up in a reaction.

Since there are more collisions, chemical reaction takes place faster. What am I measuring for?
Reactions occur when the particles of reactants collide together continuously. If they collide with sufficient energy, then they will react. The minimum amount of kinetic energy required for particles at the time of collision is called the activation energy and this theory is known as the ?collision theory?.
Collisions between reacting particles are therefore more likely to occur. All this can be understood better with a full understanding of the collision theory itself: For a reaction to occur particles have to collide with each other. Only a small percentage result in a reaction. This is due to the energy barrier that is overcoming.
...eaky fast reflexes needed to avoid an asteroid. Asteroids have collided with each other before, but it is super rare considering how far apart from each other they are.
When it comes to cars, there are plenty of safety features incorporated by manufactures to ensure a smooth and safe ride. Some of these features seat belts, airbags, and antilock brakes. Nowadays, there have been great improvements to technology within cars to aid in the avoidance of collisions altogether. Examples of these technologies include blind spot detection, backup cameras, 360-degree cameras, and autonomous driving. Many of these newer safety features are there to avoid collisions. However, whenever a collision does occur, there is not much there to protect passengers in the rear of the car. Looking into this, there is evidence that shows that rear passengers do obtain injuries in collisions and pose the threat of contributing to others injuries. So, why are rear passenger airbags not standard in your vehicle?
Varying characteristics of craters affect the impact it creates. These aspects are the density which is the compactness of an object, (Jones, 2017) the size in regards to diameter, and the height of its fall, (force of impact), of a meteorite. What is the effect of an increased density, size, and/or height of fall of a meteorite on the crater it creates? It is imperative to understand how craters are formed and the characteristics of meteorites that affect their size, in order to predict damage control. If a meteorite is forecasted to hit the Earth at a given time, and its density, size or height of fall (force of impact) are known, the size of its crater can be predicted, allowing for the victim area to prepare for a
