Main question -> How does the size of the crumple zone affect the impact force, which on a vehicle is exerted? Theoretical Exploration During a collision, objects exchange momentum and energy, causing them to move. Collisions can be divided into two groups, elastic (resilient) and inelastic (unresilient) collisions. Example of a (completely) inelastic collision is a traffic accident. During the collision, a first distortion occurs, where the colliding objects meet each other. To prevent this, all cars now have one crease zone. The crumple zone is a part of a load-bearing bodywork that absorbs the force of the impact and reduces it as much as possible. The crumple zone includes, for example, the trunk or the front around the engine compartment, …show more content…
Step-by-step plan: Make sure you have all the supplies you need Make the setup above Roll up the aluminum foil and place it over the punch pin by sliding it onto the cart. Make sure the crumple zone protrudes sufficiently. 3x aluminum roll of 5 cm. 3x crumple zone of 10 cm. 3x crumple zone of 15 cm. 3x crumple zone of 20 cm. Place the cart at a certain height on the shelf, and measure the distance with a measuring tape. Place the cart with the aluminum attached to it on the line. And then lets go, have the coaching lab measure the data. The speed, collision time and the force during the collision. Do this 3 times with all lengths. Check carefully whether the results are saved on the laptop. hypothesis. Main question: How does the size of the crumple zone affect the impact force? on a vehicle is being operated? Hypothesis: Larger crumple zone creates smaller impact force. We think that a larger crumple zone would provide less impact force on the center of the car/trolley. This would be because the surface area is larger, so the force is spread over more area. Results 5.0 - 0.01 cm. 2) …show more content…
Answer ->> As the “crumple zone” increases, the impact force becomes smaller and smaller. Explanation Answer ->> As shown by the results of our experiment, the average impact force decreases as the length of the crumple zone increases. This is because a larger crumple zone can absorb more energy during a crash. This reduces the force exerted on the central part of the vehicle. The average Ns for length, clearly shows that the impact force decreases with an increase in the crumple zone. As you can see in the results, is the least punching powergem in length 20 centimeters. With a longer crumple zone, the impact force hitting the center will be much smaller than with a smaller crumple zone. This is because the surface area is larger, so the force is spread over more area. If the research had been done with aluminum foil you would also be able to see how far the indentation/creasing is due to the deadfold of the foil. Accuracy Consideration The potential errors that could happen (or have happened) during the test or the processing of the
In a car crash, the more weight there is, the risk of injuries drops (Williams, May Twenty-second, 2015). In most semi truck accidents (about seventy percent of semi truck accidents), when only the semi truck and trailer alone are involved, there are no deaths. But when another vehicle (such as a car, van, or pickup truck ) is involved, about ninety-eight percent of the time there is at least one fatality, which is really low compared to some other means of transportation (such as a train or an airplane) (EJustice, 2012).
Many of us have gotten rock chips, but how many of us understand how those pesky rocks hit our windshield? A common misconception is that the car in front of us throws rocks "backward" and hits the following car's windshield. A rolling tire cannot throw a rock backwards. A tire is a rolling object, thus every point along the tire is moving forwards. There is no force going in a backwards direction. Only direction part of a rolling object can go is a combination of up or down, and forward.
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 ...
An elastic collision between two objects is one in which total kinetic energy (as well as total momentum) is the same before and after the collision.
The crumple zone is an essential part of any car that provides safety for the passengers during collusion with another car or object. Without any form of a crumple zone, passengers would be much more likely to suffer from injury or possibly death. For this same reason, crumple zones have existed in cars for years and are still being improved to this day. One way you can better understand a crumple zone is by creating a scale model. My group and I have made multiple crumple zones with trial and error to better understand them and how they work.
this experiment throws a ball with different weight directly downwards to a box full of sand. As the weight of the ball increases, the size of the impact crater changes, assuming the ball is always dropped from the same height as measured from the top of the sand box to the bottom of the ball. The reason behind this experiment is to determine the relationship between the mass of the ball to the size of the impact it made on the sand. The size of the impact is the dependent variable, the mass of the ball is the independent variable, and the control variable is the height at which the ball is dropped. Other controlled variables include the the surface of the sand.the experiment is limited to the depth of the sand box which is only 4 inches.
...y will occur (Demarest). By increasing the amount of padding in a helmet the time of the collision is further increased, thereby decreasing the force of an equivalent transfer of momentum.
Automobile accidents happen all around us. We see cars in the middle of the road after just rear ending each other. We see cars driving around town with big dents in them. Do you ever stop to wonder how car accidents happen? Physics; that’s how they happen. There are several aspects of physics that apply to automobile accidents.

Crashworthiness is the term used to measure a vehicle’s performance under impact conditions. A good design will be neither too strong (in which case the occupant would undergo very high acceleration) nor too weak (in which case the vehicle would absorb too little energy and not protect the occupant compartment from deformation). On the other hand, in term of mass, low mass is desirable for performance (acceleration and handling), fuel economy, and material
The Inevitable Happens"). Shallow shaking causes harsher shaking in a smaller area, this shaking loosened the weak soil to become
Craters are the most common structures associated with meteor impacts. There are two general types of craters that geologists use to identify different craters: simple craters and complex craters. Simple craters are generally bowl shaped with diameters between 2 and 4 kilometers depending on the rocks impacted (Ferriere, 2011). Generally speaking the craters in sedimentary rocks is smaller than the craters found in crystalline rocks (Ferriere, 2011). Complex craters are well named since they are a lot more complex in comparison to simple craters. The rocks in the center of the craters are generally up lifted and the walls tend to crumble inward (Ferriere, 2011). The rocks that make up the central uplift of complex craters is rock from deep beneath the floor of the crater that has been uplifted by the tremendous force from the initial impact of the meteorite (Gaz et al., 2009).
Crumple zones- are a structural feature used in automobiles. They help by absorbing the impact; this is by spreading the impact through parts of the car instead of in the one spot. This reflects back onto law number one, two and three. This is shown when the car hits the object it causes the car to slow down or completely stop (1). The crumble zone would protect the driver because all the energy has been diverted around the car, instead of the one spot. As a result of the cars mass and its acceleration, the force can be calculated (2). When the car crashes it’s most likely that the object w...
