Hold a three question interview with the claimed author. Ensure that only two questions are based on the paper's claims, eg, So, Professor Newton, is rate of fall linearly or exponentially related to mass?
- abhishekjha 7y agoWait, it isn't related to mass, right? Or am I forgetting my physics? g is m/s^2. No mass factor.
- xzcat 7y agoThat's the joke/trick, it's basically begging the question. You can out a cheater by asking a question of the form: Which is true, (A and A->B) or (A and A->C)? A cheater will fret over whether B or C is true, while someone who did the work will probably immediately identify that A is false and that the question is misleadingly worded.
- 2zcon 7y agoIt takes a very low false-positive rate before most of the people you're catching are just nervous, not cheaters.

The proper equation is: F = GmM/r^2 Where m and M are the masses of the object and earth respectively, G is Newton’s universal gravitational constant, and r is the distance between the centre of masses of the object and earth. So why is there no mass in your little g? Because the force is directly proportional to the mass of the object (holding earth’s mass constant and the distance from it constant).
- chongli 7y agoDepends on what mass you’re talking about. Double the mass of a bowling ball and you won’t notice anything different. Double the mass of the earth, on the other hand, and objects are going to accelerate toward it much more quickly!
