How Is m1 Isolated in Newton's Law of Gravitation Equation?

Click For Summary
The discussion centers on Newton's law of gravitation, specifically the equation F = G(m1•m2)/r². A user seeks clarification on how to isolate m1 in this equation. Responses indicate that the question lacks clarity, with some suggesting that the user should specify their intent. Additionally, there is a reminder that the forum does not provide direct answers to homework questions but encourages users to share their attempts for feedback. Overall, the conversation emphasizes the importance of clear communication when seeking help with mathematical equations.

Newton's equation is

F= G(m1•m2)/r squared

What is this equation to the subject of m1, please? Thank you very much for your help!

Your question is very unclear. What do you mean? What is it that you are trying to figure out?

What is the equation when m1 is the subject of it?

The equation is the equation. All of the parameters are "subjects" of it. I still don't understand what you are trying to figure out.
 
If you mean, "how to re-write this equation in the form m1 = [...]", we don't do people's homework for them (even if it's not actually a school assignment). You're welcome to post your attempt at it in the "Precalculus Mathematics Homework" section:

and then people will give hints or correct mistakes as necessary.
 

Thread 'Mousetrap Car Energy efficiency'

For simple comparison, I think the same thought process can be followed as a block slides down a hill, - for block down hill, simple starting PE of mgh to final max KE 0.5mv^2 - comparing PE1 to max KE2 would result in finding the work friction did through the process. efficiency is just 100*KE2/PE1. If a mousetrap car travels along a flat surface, a starting PE of 0.5 k th^2 can be measured and maximum velocity of the car can also be measured. If energy efficiency is defined by...
