Using our understanding of orbits, which orbits (near or far) are moving more slowly?

near

far

Using our understanding of orbits, objects in lower, near-in orbits move slower than objects in higher, far-out orbits.

Here's a set of examples:

International Space Station ...

Orbital height -- 254 miles

Speed in Orbit -- 76 mi/sec

Geostationary TV satellite ...

Orbital height -- 22,200 miles

Speed in orbit -- about 1.9 mi/sec

Moon ...

Orbital height -- 238,000 miles

Speed in orbit -- about 0.6 mi/sec

c) up is the direction the magnetic force is acting on the charge.

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.
