If an aircraft is flying in a straight line, are there no forces acting on it, or is there an upward force acting on it?

Homework Help Overview
The discussion revolves around the forces acting on an aircraft flying in a straight line, particularly in the context of aerodynamics and Newton's laws of motion.
Discussion Character
- Conceptual clarification, Assumption checking
Approaches and Questions Raised
- Participants explore the relationship between lift and weight, questioning whether forces are acting on the plane despite it moving at constant speed. There is also a focus on understanding Newton's laws in this scenario.
Discussion Status
Some participants have provided insights into the nature of forces acting on the aircraft, noting that while there is no net force due to balanced lift and weight, forces are indeed present. The discussion appears to be productive, with participants engaging in clarification and exploration of concepts.
Contextual Notes
The original poster expresses a desire to learn about aerodynamics, indicating a potential lack of background knowledge in physics concepts, which may influence their understanding of the topic.

What do you think? (I assume you mean in a straight line with constant speed.)
What do Newton's laws tell you?

Hello, thank you for the reply.
I'm only 11 years old, but I want to be a pilot when I'm older so I'm trying to learn what I can about aerodynamics and I came across this question, please go easy on me
I think from what I've read, that there is equal lift and equal weight, so there is no resultant force, but the question asks "are there any forces acting on the plane?" so I'm just a bit confused about what to answer, thank you for your time.

I think you've got it: The key is that since the plane is moving in a straight line at constant speed there is no net force on it. But there are certainly forces acting on it. Weight and lift are two of them.
