Momentum

Thermal expansion coefficients become negative, contradicting the model's assumptions.

Air resistance becomes more significant even though it's a closed system.

Relativistic speeds are reached, requiring Einstein's theory of relativity.

Quantum tunneling alters particle behavior in ways not accounted for by classical mechanics.

It decreases gradually until it reaches zero.

It remains constant if there are no other changes.

It becomes zero immediately.

It increases over time.

The satellite will crash into the planet because its speed will cause it to lose altitude more rapidly than gravity can pull it back up.

The orbit becomes more elliptical with the major axis aligned along the direction the motion was increased, thanks to an imparted angular momentum shift caused solely by the added velocity component orthogonal to the radial line joining the center of the large body and the small one.

The satellite moves into a higher orbit around the planet due to increased kinetic energy overcoming some gravitational pull from the planet at that instant in time before eventually settling into a new balance point where centripetal acceleration needed matches gravity provided at that altitude.

The orbit radius stays exactly the same because any changes in speed are immediately negated by an equal change in direction maintained via inertia alone.

None of these options will increase the angular momentum of the system

Total kinetic energy oscillates post-collision within the combined mass without loss or gain overall.

Total kinetic energy increases as potential energy converts into kinetic during impact.

Total kinetic energy remains constant since no external work is done on the system.
