The automotive mechanical and collision repair industries have always had changes over the years‚ requiring new diagnostic tools and new hand and air tools frequently. However‚ the newest upcoming changes may require a change in how technicians work on vehicles in addition to new diagnostic and repair tools and equipment. Vehicles no longer use only steel or fiberglass‚ so collision repair technicians must learn new skills‚ including welding aluminum and high strength steel. Almost all automotive

set energy to loss In collision Units are Joules K=1/2 mv^2 When something is written in speed and you need velocity for equation just square the speed Joules equals kg times m^2/s^2 Velocity has more effect on kinetic energy than mass. Still objects have no kinetic energy. Hint: Energy variables are capital Momentum proportional to mass and velocity p=mv Units= kg time m/s And is vector in as direction as velocity Conservation laws are applied in closed systems only Collisions are closed Momentum

tetrasulfide. The collision theory briefly: For a reaction to occur particles have to collide with each other. Only a small percent result in a reaction. This is due to the energy barrier to overcome. Only particles with enough energy to overcome the barrier will react after colliding. The minimum energy that a particle must have to overcome the barrier is called the activation energy‚ or Ea. The size of this activation energy is different for different reactions. If the frequency of collisions is increased

hour). The collision will change both cars’ momentum. But‚ because no force from outside the system has acted on the cars‚ their total momentum remains zero"(DiscoverySchool.com). Back to my example‚ although both cars were going the same speed‚ one driver lived while the other died. While this may seem like driver A was wearing his lucky tie‚ probing deeper into the case proves that physics saved his life. Sir Isaac Newton was the first man to explain what happens in a collision. He proposed

take place‚ we use the collision theory. Collision Theory The collision theory states that for a reaction to take place between reacting particles (ions‚ molecules or atoms)‚ it is essential that they collide. B A B A The collision theory goes further to state that for a reaction to take place‚ there must be sufficient energy in the collision. If there isn’t sufficient energy‚ the colliding particles simply bounce off each other. Compound A-B formed when the collision has sufficient energy

hammering techniques. Automotive body repair shops are very common around the world because collisions occur all the time. The automotive body repair career may take up most of one’s time and it will take effort from one’s part but it will be worth it at the end. The history of automotive body repair‚ when it first started the automobiles were easier to repair since the car designs were simpler. Since collision repair was a profession necessitated by Americans‚ new job opportunities were available.
