Answer part A

• The rocket’s engines create lift by pulling the Earth downward.

• The rocket moves upward because Earth’s gravity weakens near the surface.

• The rocket gains energy from the Sun’s heat, causing it to rise.

• The rocket thrusts upward as a result of expelling gas in the opposite direction, following Newton’s Third Law.

Answer part B

• Since neither I nor the wall moves, no forces are acting at all.

• The wall absorbs all of my force, so no force is exerted back on me.

• I would be able to feel the wall pushing back against me because even though I am unable to push the wall, it would still exert an equal but opposite force back toward me.

• I would not feel any force from the wall because I am not strong enough to move it.
