Which type of motion involves movement along a straight path?

The correct answer is linear motion. This type of motion specifically refers to the movement of an object along a straight line. In linear motion, the object does not change its path and moves in a consistent direction, which can be either forward or backward without any deviation or rotation involved.

In physics and mechanics, linear motion can be characterized by parameters such as speed, velocity, and acceleration, all of which are relevant when analyzing objects that move in a straight line. This contrasts with other types of motion, such as angular motion, which involves rotation around an axis, and general motion, which can combine various types of motion, including linear and angular. Understanding linear motion is fundamental in aviation and engineering as it applies to a range of scenarios including the flight path of an aircraft during takeoff and landing.
