Answer
The full name for the unit of W (weight) in the equation
is newton.
Explanation
## Step 1: Identify the variablesIn the equation
,
stands for weight of the object,
represents the object's mass, and
refers to the acceleration due to gravity.## Step 2: Understand the unit for each variableBy definition, the acceleration due to gravity
is frequency measured in meters per second squared (m/s²). The mass
of an object is generally measured in kilogram which is a unit of mass. ## Step 3: Determine the unit of W To find
(weight), multiply mass
by acceleration due to gravity
. Effectively, this implies that you're multiplying kilograms (mass) by meters per second squared (acceleration), which would result in units of "kilogram meter per second squared," i.e., "kilogram meters/ (second)²."### Fundamental formula:
While this unit may sound complex, it has a commonly-known equivalent in physics which is referred to as "newton," named after Sir Isaac Newton in recognition of his work in mechanics.
