Question about something reaching exactly +

  • Thread starter MaZnFLiP
  • Start date
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.
 
  • #4
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.
 
  • #5
Oh okay. That makes sense now. So that would mean that 2(-9.81m/s^2) = v^2/r right?
 
  • #6
Right. Except I wouldn't put a minus sign on g in this context. g is just a magnitude, not a direction.
 
  • #7
Oh okay. Thanks so much!
 

FAQ: Question about something reaching exactly +

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.
