Both are Nuclear weapons that are used through the Nuclear Fission. The fissile Uranium is the U-235 the Fissile Plutonium is the PU-242.

Uranium has the 'ease' of being exploited by both shot and implosion. Plutonium can only be exploited by implosion.

Detonation by firing consists of a piece of fissile uranium that is fired at a target of fissile uranium. In this way a critical mass is generated when the explosion is combined. This method is not feasible for plutonium since, due to premature firing, contamination of Plutonium is generated due to its time constant for critical fission being less than that of U-235.

The implosion method is used by Plutonium (and it can be used by uranium or a combination of both). Basically, plutium is surrounded by a mass of explosives that, when exploded, compress the mass, generating the critical mass generated by the explosion.

Therefore the plutonium bomb is more difficult to build.

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
