think about this, there was lots of testing of nucler bombs testing in the 60-70-80 -90s or before dont you think that would make the earth spin faster, the force of them going off must have some efect on the earth.

Why would the Earth spin faster? This makes no sense. Have you ever taken a pysics course?
Do this experiment. Take a firecracker and tape it to the side of a basketball. Light the firecracker. Now spin the ball. Did it change anything? Now, keep in mind that, relative to the size of the Earth, a nuke is smaller than that firecracker.

No, a nuclear explosion ,like any other, has symmetry, it has force equal in all directions, so any force encouraging spin would be counter balanced by force discouraging spin, they will be equal and cancel (unless it was some how shape chargd). Anyway, compared to other forces (like tidal force of the moon) this is extremely negligible.The earth spins because momentum is left over from the formation of the solar system, the earth used to spin faster, the earths spin is slowing down, at some point it will stop spinning, or not, because the sun will super nova before this happens.

The Earth spins at 7.292115 x 10^-5 rad/sec. On the equator a person has a linear speed of v=rw where s is your speed, r the radius (6378 km) and w your angular velocity (7.292 x 10^-5 rad/sec). That comes to 465 m/sec. Your centripetal acceleration is v^2/r. In this case about 3.39 x 10^-2 meters/sec^2. The Earth's gravity accelerates you towards the Earth at 9.8 meters/sec^2. In other words, gravitational acceleration is stronger than your centripetal acceleration, even on the equator. If the Earth revovled 10000 rpm, that would be 2 PI rad/rev * 10,000 revs * 1 min/60 sec = 1,047 rad/sec. On the equator, your linear speed would be 6.68 x 10^ 9 meters/sec. Your centripetal acceleration would be 6.99 x 10^12 meters/sec^2. That's about 700 billion times stronger than your gravitational acceleration. You'd be flung out into space in an instant. If you were located on the North or South Pole, you would experience 0 centripetal acceleration, since you're standing on the Earth's rotational axis. If you were located about 7.5 meters (about 25 feet) away from one of the poles, your centripetal acceleration would equal gravitational acceleration and you'd feel weightless. Edit: When I think about it, this wouldn't be true. That close to the poles, gravitational attraction is directly down while centripetal acceleration would be virtually horizontal. The forces would have to be exactly opposite each other to make you feel weightless. Edit: There's 1.609 meters in a mile and 3600 seconds in an hour, so 465 meters/sec converts to about 1,040 mph at the equator. You have to multiply by the cosine of your latitude to get your personal speed. At 45 degrees latitude (North or South, it doesn't matter), your speed would be about 735 mph. At the pole, it would be 0 mph.

The Earth won't spin faster but the setting off of atomic bombs could cause minor earthquakes.

Nuclear explosions have no effect on rotation since the force of the blast is straight down and in all directions. They could have some effect on the orbit, but none were large enough to do anything.
The shifting of a tectonic plate can affect rotation, the one that caused the huge tsunami off Indonesia did change the rotation a tiny bit.

well the force of the bomb would push the earth away from the bombs if anything. Not to the side making it spin faster. But even then, it would be a very small amount.

You`re right. When I was young, there were 36 hours in a day and 12 days in a week, and weekends took 3 weeks to arrive. But now, sixty years later, there are only 8 hours in a day ,2 days in a week, the weekend has just gone a n d I a m b e g i n i n g t o l o s e m y g r i ........

Compared to the energy and momentum of the earth, a nuclear weapon is like a flea fart.
You silly humans think you are soooooo powerful.

The Earth isn't spinning faster. If it was the days would be shorter and clocks and calendars would have gone awry.
