Question

practice it! students are testing different paper airplane designs to see which design will allow a plane to go the farthest. one airplane is folded and students attach a paperclip to the front of it. after throwing the plane, it travels about fifty feet and then starts to fall to the ground. which of the following accurately explains why the plane eventually falls to the ground? the force of air resistance stops acting on the plane. the plane was not designed to carry a load like the paperclip. the paperclip creates a magnetic force that attract, he plane to the ground. the force of gravity pulls all things on earth toward the ground.

Explanation:

• Air resistance is always present when an object moves through air, so the first option is incorrect.
• Just because a paperclip is added (a small load), it doesn't directly mean the design was not for carrying a load in a way that would make it fall (this option is too vague and not a fundamental reason).
• A paperclip doesn't create a magnetic force that would pull the plane to the ground (paperclips are not magnets in this context).
• Gravity is a fundamental force on Earth that acts on all objects with mass, pulling them towards the center of the Earth (ground).

Answer:

The force of gravity pulls all things on Earth toward the ground.
