Answer the following: What are the units of mass and the units of weight for the metric system? What are the units of mass and the units of weight for the English system?

Explanation:

Units are measure of a quantity. There are two types of units,

The fundamental units

The derived units

The fundamental units are units that are independent i.e they can stand alone while derived units are derived from fundamental units (They are dependent)

The fundamental units are the units of fundamental quantities (Length, mass and time)

Length is measured in metres (m)

Mass is measured in kilograms (kg)

Time is measured in seconds(s)

This are called the standard units where other units are derived.

Other units of mass are grams

Weight is the product of mass and acceleration due to gravity

Weight = mass×acc due to gravity

W = mg

Using units

W = kg × m.s²

Since acceleration is measured in m/s²

W = kgm/s²

Hence the metric unit of weight is kgm/s² or Newtons
