A super duper jump
Imagine if everyone in the world gathered together and jumped at the same time. What would happen? Would the world spin immeadiately? Would the jump cause people to rebound madness go flying?
There are approximately 7 billion people in the world. The average weight of a person is 80.7 kg. Now 7,000,000,000 * 80.7 kg = 5.649*10^11. That’s a lot of weight. In comparison the mass of the earth is 5.972*10^24. So it really isn’t that much at all.
Now all these people would gather in T.F. Green Airport in Warwick RI. The airport is only 11 acres but there is a parking garage that has a few floors. The rest of the population will be able to gather in the parking lot and some of the roads near the airport.
Using a momentum equation
M(people) * V(jump) = M(earth)*V(earth)
Let’s say the people jump at a velocity of 2m/s
(5.649*10^11)(2) = 5.972*10^24(V)
V = 1.891*10^-13
This number is so infantismally small so it shows that the earth would barely move.
Of course it is kind of difficult to gather everyone in the small area of Rhode Island. I was expecting a velocity a little bigger but since the mass of the earth is so great it cancels everything out.
