Question

3.
is the change in the position of an object?
a:motion

b:linear motion

​

Answer 1

Answer:

Linear motion, also called rectilinear motion,[1] 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; and non-uniform linear motion with variable velocity or non-zero acceleration. The motion of a particle (a point-like object) along a line can be described by its position {\displaystyle x}x, which varies with {\displaystyle t}t (time). An example of linear motion is an athlete running 100m along a straight track.[2]
