motion in a straight line.
Answers
Answer:
If a body travels in a straight line and covers an equal amount of distance in an equal interval of time, then it is said to have uniform motion. In simple words, a body is said to have uniform acceleration if the rate of change of its velocity remains constant.

Answer:
What is Motion in a Straight Line?
If an object changes its position with respect to its surroundings with time, then it is called in motion. It is a change in the position of an object over time. Motion in a straight line is nothing but linear motion. As the name suggests, it’s in a particular straight line, thus it can be said that it uses only one dimension.
Types of Linear Motion
The linear motion, also called the Rectilinear 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
Linear motion is the simplest kind of one-dimensional motion. As Newton’s first law of motion suggests, an object will either be in rest or continue to move in a straight line with a uniform velocity unless and until an external force is applied to it.
You are suggested not to get confuse linear motion with general motion. As we discussed, linear motion is a one-dimensional motion but in general, the motion has magnitude and direction both, i.e. an object’s position and velocity are described in vector quantities.
Uniform Motion in a Straight Line
If a body travels in a straight line and covers an equal amount of distance in an equal interval of time, then it is said to have uniform motion. In simple words, a body is said to have uniform acceleration if the rate of change of its velocity remains constant.
