# Question about something reaching exactly +

• MaZnFLiP
In summary, the conversation discusses a question about reaching exactly +2G acceleration on a turn and the difference between tangential and normal acceleration. It is explained that normal (centripetal) acceleration can be calculated using the formula v^2/r, where v is velocity and r is the radius of the turn. It is then clarified that g is a magnitude and not a direction.

[SOLVED] Question about something reaching exactly +

## Homework Statement

Sorry, I accidentally hit the enter button. Anyways my question is about something reaching exactly +2G acceleration on a turn. I tried asking my friends and teacher about it but it didn't exactly make sense the way they explained it. I just want to know what that means to have a +2g acceleration when turning

Tangential or normal? I think you'll have to explain more about what your friends and teachers explained and express that in the form of a question.

I think normal.

Normal (centripetal) acceleration is given by v^2/r, where r is the radius of the turn and v is the velocity. If that's equal to 2g, then 2g=v^2/r.

Oh okay. That makes sense now. So that would mean that 2(-9.81m/s^2) = v^2/r right?

Right. Except I wouldn't put a minus sign on g in this context. g is just a magnitude, not a direction.

Oh okay. Thanks so much!

## 1. What does "exactly +" mean in a scientific context?

In science, "exactly +" refers to a specific value or measurement that has been measured or observed with precision. The "+" sign indicates that the value is positive, meaning it is greater than zero.

## 2. Can something ever reach exactly +, or is it just an ideal concept?

In theory, something can reach exactly + if it is measured with perfect accuracy. However, in reality, there is always some margin of error in measurements, so it is not always possible to have an exact value of +.

## 3. How is the concept of "exactly +" important in scientific experiments and research?

The concept of "exactly +" is important in scientific experiments and research because it allows for precise and accurate measurements, which are essential for drawing valid conclusions and making scientific discoveries.

## 4. Is it possible for something to reach exactly + and then change to a different value?

Yes, it is possible for something to reach exactly + and then change to a different value. This can happen due to various factors such as external influences, natural processes, or experimental errors.

## 5. How do scientists ensure that their measurements are as close to exactly + as possible?

Scientists use various techniques and tools such as precise instruments, controlled experiments, and statistical analysis to minimize errors and obtain measurements that are as close to exactly + as possible.
