Answer 1

Answer:

What is the nature of the distance time graphs for uniform and non-uniform motion of an object moving in a straight line? (1) Uniform - straight line, Non-uniform - straight line (2) Uniform - straight line, Non-uniform - curved (3) Uniform - curved, Non-uniform - Straight line (4) Uniform - curved, Non-uniform - curved

Answer: (2)

Distance-Time Graph for Uniform Motion

A body is said to be in uniform motion when the body covers the equal distance in equal time intervals. Let’s consider a time interval of 1 second, If a body covers 10 meters in the first 1-second then it should cover 10 meters in every second from there on, this will indicate that the body is in uniform motion. Let’s draw a graph for uniform motion.

As in uniform motion, the distance time graph would be a straight line, because the equal distance is covered in equal units of time.

Distance-Time Graph for Uniform Motion

Distance-Time Graph for Non-uniform Motion

Non-uniform motion is defined as the motion of an object in which the object travels with varied speed and it does not cover the same distance in equal time intervals, irrespective of the time interval duration.

The distance-time graph for non-uniform motion is not a straight line since speed is variable, it can be a curve or a zigzag line.

Hope this answer help you..
