RECTILINEAR MOTION Meaning and
Definition
-
Rectilinear motion refers to the movement of an object along a straight line. In physics, it is a type of motion characterized by the object's path being a straight line, where the object moves in a straight and direct manner without any deviation or turning. This type of motion is commonly observed in everyday life, such as when a car drives straight down a road or when a ball is thrown directly upwards and then falls back down.
In rectilinear motion, the velocity of the object remains constant unless acted upon by external forces, such as friction or gravity. The object's speed can change if external forces are present, but its direction remains unaffected as long as there are no perpendicular or tangential forces acting on it.
Rectilinear motion can occur in various contexts, such as the motion of planets in space, where their paths can be approximated as straight lines over short time durations. It is commonly studied and analyzed in physics and mechanics to understand the behavior and dynamics of moving objects. The equations of rectilinear motion involve parameters such as displacement, velocity, time, and acceleration, which enable the calculation and prediction of an object's motion along a straight line.
Overall, rectilinear motion describes a basic and straightforward type of motion wherein an object travels in a straight line without any deviation or change in direction.
Etymology of RECTILINEAR MOTION
The word "rectilinear" is derived from the Latin word "rectus", meaning straight or direct, and the word "linear", from the Latin word "linea", meaning line.
The term "rectilinear motion" combines these two components to describe the type of motion that occurs in a straight line. The word "motion" is derived from the Latin word "motio", meaning movement.
