Question

DEFINE THE FOLLOWING TERMS:-

a) uniform motion b) density

​

Answer 1

Answer:

1. Uniform Motion: Definition: This type of motion is defined as the motion of an object in which the object travels in a straight line and its velocity remains constant along that line as it covers equal distances in equal intervals of time, irrespective of the duration of the time
2. The density, of a substance is its mass per unit volume.

Answer 2

Answer:

A body is said to be in uniform motion if it travels equal distances in equal intervals of time, no matter how small these time intervals may be. If we draw distance time graph for uniform motion then it will be straight line.

Density is a measure of mass per volume. The average density of an object equals its total mass divided by its total volume. An object made from a comparatively dense material (such as iron) will have less volume than an object of equal mass made from some less dense substance (such as water).
