Charlotte throws a paper airplane into the air, and it lands on the ground. which best explains why this is an example of projectile motion? the paper airplane’s motion is due to horizontal inertia and the vertical pull of gravity. a force other than gravity is acting on the paper airplane. the paper airplane’s motion can be described using only one dimension. a push and a pull are the primary forces acting on the paper airplane.

The answer would be:

The paper airplane's motion is due to horizontal inertia and the vertical pull of gravity.

Here is why:

A projectile is an object that when "projected" or is in the air will only be influenced by gravity. Only the downward force of gravity acts on the object. You might be wondering, if only gravity acts on an object then what about the horizontal movement?

Well, a projectile's horizontal movement is dependent on its inertia. It will continue to move forward at a constant velocity. If we were to switch off gravity that paper plane would move horizontally forever. It is when gravity is applied would we see it moving downwards.

I hope you get it.

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
