<p>Does anyone know how to find the initial mutual force of attraction between the Earth and another object?</p>

<p>wouldn't you just use the Universal Gravitation Equation?</p>

<p>Force = GMm/r^2</p>

<p>where G is the universal gravitation constant (you can find it on the internet), M is the mass of object 1, m is the mass of object 2, and r is the distance between the two objects.</p>

<p>Thanks! Yeah, that's probably right. Left my textbook at school, so yeah...thanks a lot!</p>
