In summary, a quick collision question is a simple yes or no question commonly used in scientific research to quickly gather data from a large sample size. The purpose of asking these questions is to efficiently collect data and gain initial insights into a topic or hypothesis. They differ from other types of questions in that they are straightforward and used for data collection rather than in-depth exploration. Examples of quick collision questions include ones about preferences or experiences and their benefits in research include efficient data collection, initial insights, and generating new research questions or hypotheses.

If a truck and a car collide will they both have the same change in velocity?

Since the momentum before has to equal the momentum afterward wouldn't the change in the velocity also be equal?

Thank you.

No, because they have different masses. Their change in momentum will be equal, p=mv.

I can confirm that the change in velocity for both the truck and the car will not necessarily be equal in a collision. While it is true that the total momentum of the system (truck and car) will be conserved, the distribution of this momentum between the two objects may vary. This is due to the difference in mass and velocity between the truck and the car. The more massive object, in this case the truck, will experience a smaller change in velocity compared to the less massive car. This is due to the fact that momentum is a product of both mass and velocity. Therefore, while the total momentum may be conserved, the individual changes in velocity for the truck and the car may differ. It is also important to note that other factors such as the angle of collision, the materials of the vehicles, and the presence of external forces can also affect the change in velocity.
 

What is a quick collision question?

A quick collision question is a type of question commonly used in scientific research to quickly collect data from a large sample size. It involves asking a simple question that can easily be answered with a yes or no response.

What is the purpose of asking a quick collision question?

The purpose of asking a quick collision question is to gather data in a short amount of time. This type of question is useful for collecting data from a large sample size and can provide initial insights into a topic or hypothesis.

How are quick collision questions different from other types of questions?

Quick collision questions are different from other types of questions because they are simple and easy to answer with a yes or no response. They are also used for data collection rather than in-depth exploration of a topic.

What are some examples of quick collision questions?

Examples of quick collision questions include "Do you prefer coffee or tea?" or "Have you ever traveled outside of your home country?" They are typically short, straightforward, and can easily be answered by a large number of people.

What are the benefits of using quick collision questions in research?

The benefits of using quick collision questions in research include collecting data efficiently from a large sample size, providing initial insights into a topic, and easily comparing responses between different groups. They can also be useful for generating new research questions or hypotheses.
