A object moves in a constant speed is said to be in uniform motion so this is uniform motion.

Constant Speed in a Straight Path:
Flying an aircraft at a constant speed in a straight path is an example of linear motion. This type of motion involves an object moving in a straight line at a consistent velocity. Let's break down this scenario in detail:

Aircraft:
- The aircraft is a mechanical device designed for flight. It is propelled through the air by engines, wings, or rotors.
- In this case, the aircraft is moving with a constant speed, meaning it is maintaining the same velocity over time.

Constant Speed:
- Constant speed refers to the rate at which an object covers distance in a specific amount of time without any changes in velocity.
- When an aircraft flies at a constant speed, it means that it is not accelerating or decelerating, but rather maintaining a steady pace.

Straight Path:
- A straight path indicates that the aircraft is moving in a linear direction without deviating from its course.
- This type of motion is characterized by movement along a single line, with no changes in direction.

Explanation:
- When an aircraft flies at a constant speed in a straight path, it demonstrates linear motion in a controlled and predictable manner.
- The pilot maintains the aircraft's velocity and heading to ensure a smooth and efficient flight.
- This type of motion is essential for navigation, as it allows the aircraft to reach its destination accurately and on time.
In conclusion, flying an aircraft at a constant speed in a straight path exemplifies linear motion, showcasing the precise control and coordination required for successful flight operations.
