Question

motion along a straight line is called _____ motion​

Answer 1

When an object moves along a straight line, the motion of the object is called rectilinear motion.

Answer 2

Answer:

Linear Motion / Rectilinear Motion

Explanation:

Linear motion , also called rectilinear motion , is one-dimensional motion along a straight line , and can therefore be described mathematically using only one spatial dimension .The linear motion can be of two types :

• Uniform Linear Motion with constant velocity or zero acceleration  
• Non-Uniform Linear Motion with variable velocity or non-zero acceleration.  

An example of linear motion is an athlete running 100 m along a straight track.
