What does fraction of G mean? (SI units)

Click For Summary

Homework Help Overview

The discussion revolves around understanding the concept of expressing a calculated acceleration as a fraction of the acceleration due to gravity (g) in the context of a physics problem involving a car's acceleration from rest to a certain speed.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants explore the meaning of "fraction of g" and its relation to the acceleration calculated. There are questions about how to express the acceleration in terms of g, and some participants seek clarification on the definition of g itself.

Discussion Status

Some participants have provided definitions and values for g, while others are questioning how to proceed with the calculation of the fraction. There is an ongoing exploration of the relationship between the calculated acceleration and g, but no consensus has been reached on the method to solve for the fraction.

Contextual Notes

Participants express uncertainty about the interpretation of the problem and the calculations involved, indicating a need for further clarification on the relationship between acceleration and gravity.

I have search my gigantic physics book everywhere for this but I can't seem to find it...does anyone know what it means

Seee the problem is
What constant acceleration, in SI units, must a car have to go from zero to 71.0 mph in 13.0 s? I solved that it was 2.44 m/s^2
but then it askes What fraction of g is this?
I have know clue what that means except it is post to be a percent...
please explain what g means
 
Physics news on Phys.org
g is acceleration due to gravity, 9.81 \frac m s
 
Thank you so much
 
Integral said:
g is acceleration due to gravity, 9.81 \frac m s
\frac{m}{s^2}
 
Can someone explain HOW to solve it?
I understand that g=gravity=9.81. So what now? How do it solve the fraction?
I know it is not 9.81/acceleration or acceleration/9.81...
 
Well since g * fraction = a, what does that tell you about your fraction?
