The difference between the two speeds. So if one car is traveling at 60mph and the other is 70mph, it would be a 10mph difference since they are traveling in the same direction. Now, if they were colliding head on, it would be 130mph total speed.

Also, 2 cars traveling at exactly the same speed and direction (assuming they start a certain distance apart) will never collide and will maintain that exact distance they started apart.

How does a forensic engineer use the laws of conservation of energy in a crash investigation?

In a crash situation it is usual for kinetic energy (the energy of motion) to be converted into distortion of the the impactors, displacement of the impactors, heat and sound. Depending on what you want to calculate you can work out the forces required to - distort the the impactors, displace of impactors and create the heat and sound observed to work out the initial kinetic energy of the impactors - how fast and in which direction they were moving.


What do we have to look at to better understand crash dynamics?

To better understand crash dynamics, we need to look at factors such as the speed of the vehicles involved, the weight and size of the vehicles, the angle of impact, the use of safety restraints, and the condition of the road and weather during the crash. Analyzing these factors can provide insights into how crashes occur and how they can be prevented in the future.


Kientic energy in a crash?

In a crash, the kinetic energy of a moving object is converted into other forms of energy, such as heat, sound, and deformation of the object involved in the crash. The amount of kinetic energy involved in the crash depends on the mass and velocity of the objects involved.


Energy that is dissipated in a crash is called?

Kinetic Energy is energy that is dissipated in a crash.


What is difference between crash and crush?

"Crash" typically refers to a sudden and violent impact or collision between objects, such as vehicles. "Crush," on the other hand, usually implies applying pressure to an object or person with force, resulting in deformation or destruction.

What is the purpose behind having crash test dummies?

Crash test dummies provide an invaluable service for safety testing of vehicles. Crash test dunnies can provide information on how a person will be affected in different types of accident scenarios, and help in designing safer vehicles.


Do booster seats have to be anchored in order to ensure proper safety for children in vehicles?

Yes, booster seats should be anchored to ensure proper safety for children in vehicles. Anchoring the booster seat helps secure it in place and prevents it from moving during a crash, providing better protection for the child.

What are the safety benefits of using a tethered booster seat for children in vehicles?

Using a tethered booster seat in vehicles provides added safety for children by reducing the risk of head and neck injuries in the event of a crash. The tether secures the booster seat to the car, preventing it from moving and providing extra protection for the child.


Can two cars moving with the same speed collide?

Yes. If in opposing directions, obviously. But if they were in parallel to each other, they could still touch and damage each others bodies.However, two cars moving with the same velocity cannot collide.


Are dog seat belts safe for use in vehicles?

Dog seat belts can help keep dogs safe in vehicles by preventing them from moving around or being thrown in the event of a sudden stop or crash. However, it is important to choose a high-quality seat belt that is properly fitted to your dog to ensure maximum safety.
