True.
The boundary between warm and cold air masses always slopes upwards over the cold air.
in the south, tropical air masses would be moving north or upwards. polar air mass would be moving sideways or west.
The masses of fission products are of course smaller than the masses of uranium isotopes.

The question "Do things with larger masses have larger velocities?", by itself, is meaningless, as you did not provide enough information. Things with larger masses do require more force to accelerate them than things with smaller masses. Things with larger masses do have more kinetic energy than things with smaller masses for the same velocity.
Force accelerates stationary masses as acceleration a=f/m; theacceleration is inverse to the mass. The smaller the mass the larger the acceleration and the larger the mass the smaller the acceleration.
The force of gravity is stronger between larger masses, and weaker between smaller masses. That's why there's more force between you and the Earth than there is between you and a bowling ball, for example.
True.
Stars with larger masses have stronger gravity; this results in more pressure; which in turn makes the star hotter. As a result of the higher temperature, they will shine brighter, and burn their fuel much faster.
Nuclear fusion is the process of merging nuclei with smaller masses into a nucleus with a larger mass.
Atomic fusion occurs when masses combine to form elements with larger mass.
The boundary between warm and cold air masses always slopes upwards over the cold air.
Gravity is a pair of forces between masses. The strength of the forces depends on the masses of the masses and the distance between them. It doesn't depend on their motion, except that it may be getting larger or smaller over time if they're moving closer together or farther apart.
Gravity is the resulting force created, as infinitely smaller and smaller masses orbit larger masses in space, which allows matter to become compacted into smaller and more dense proximity, and at the same time, creating a relative void in space, which causes the less massive of two bodies in space, to continually fall toward the more massive body in space.
The force of gravity is a force between any masses. The force is always attractive. Larger masses attract one another more strongly; on the other hand, at greater distances the force is less.
... different. Kinetic energy is proportional to the square of the speed, wherease momentum is proportional to the speed.
