Question

What is the definition of rectilinear motion

Answer 1

Rectilinear motion means motion along a straight line. This is a useful topic to study for learning how to describe the movement of cars along a straight road or of trains along straight railway tracks.

Answer 2

Answer: When an object goes in a straight path, it is said to be in a linear motion and when two objects are traveling parallel to one another in a straight line, they are said to be in a rectilinear motion.

Explanation:

• One spatial dimension can be used to quantitatively represent linear motion, also known as rectilinear motion, which is motion in one dimension in a straight line.
• There are two different types of linear motion: non-uniform linear motion, which has variable velocity, and uniform linear motion, which has constant velocity (zero acceleration) (non-zero acceleration).
• A particle's (an item resembling a point) motion down a line can be explained by its position, x which fluctuates with  t. (time). An athlete running a 100-meter dash along a straight track is an illustration of linear motion.
• The most fundamental type of motion is linear motion and Newton's first law of motion states that inert objects will continue to move in a straight path with a constant speed.
• In real-world situations, external factors like gravity and friction can cause an object to change its direction of travel, making it impossible to describe an object's motion as linear.
