Question
I know that the equation F=GmM/r^2 shows how there is anattractive force between all objects. But I was wondering why twoobjects don't reduce the distance between them all the way to 0 andstick together. Is it because objects on earth have a strongerattraction to the earth than they do each other? Thanks I know that the equation F=GmM/r^2 shows how there is anattractive force between all objects.

Explanation / Answer
the object's weight is w = m * gsurface where gsurface is the acceleration due to gravityat the planet's surface.The force of gravitational attraction,asgiven by Newton's law of gravity,is FM on m= (G * M * m/R^2) here,G = 6.67 * 10^-11 Nm^2/kg^2 the magnitude of the gravitational attraction between twoobjects of mass M and m is small when compared to the gravitationalforce between them.Therefore the two objects do not stick togetherand the distance between them does not become zero. where gsurface is the acceleration due to gravityat the planet's surface.The force of gravitational attraction,asgiven by Newton's law of gravity,is FM on m= (G * M * m/R^2) here,G = 6.67 * 10^-11 Nm^2/kg^2 the magnitude of the gravitational attraction between twoobjects of mass M and m is small when compared to the gravitationalforce between them.Therefore the two objects do not stick togetherand the distance between them does not become zero.
