The Wednesday test launch stored more potential energy, and launched the spacecraft at a faster speed because the stronger magnetic field closer to the magnet resulted in a greater increase in potential energy.
The Wednesday launch stored more potential energy, and launched the spacecraft at a faster speed because a movement of the repelling magnets closer together when the magnets were already quite close acted against a stronger magnetic force than a similar-sized move when the magnets were not as close to each other.
<u>Explanation:</u>
Magnetic forces are stronger closer to magnets. The Wednesday test launch stored more potential energy, and launched the spacecraft at a faster speed because the stronger magnetic field closer to the magnet resulted in a greater increase in potential energy.
