No change in body weight in two weeks for an 8-week old rat may suggest that fat is being lost while muscle is gained in this type of scenario.
What is Weight?
This is used to describe how bulky a body is and is also referred to as the force which acts on an object as a result of the force of gravity which acts downwards. The formula for weight is denoted as:
W = mg
where m is referred to as the mass and g as the gravitational force.
