What is the direct effect of decreasing the distance between two repelling magnets in a launcher setup?

The stored potential energy decreases.

The repulsive force and stored potential energy both increase.

The repulsive force decreases, but the potential energy increases.

The magnetic poles of the magnets will automatically flip.

An engineer wants to design the most powerful magnetic cannon possible. According to the principles of energy conversion, which design goal should be prioritized to achieve the highest launch velocity?

Maximizing the initial stored potential energy in the system.

Minimizing the mass of the projectile to an absolute minimum.

Using magnets with the weakest possible fields to save energy.

Increasing the friction within the launch tube for a better grip.

Kinetic energy is converted into potential energy.

Potential energy is converted into kinetic energy.

Thermal energy is converted into potential energy.

Electrical energy is converted into kinetic energy.

A greater initial force results in a slower launch speed.

The initial force has no direct relationship to the final launch speed.

A greater initial force results in a greater launch speed.

The launch speed is determined only by the mass of the spacecraft.
