English the language the speak of science.
Scientists use both; but normally mass is used somewhat more than weight.
they are the same thing.
A weight hanger is used to suspend weights on a laboratory balance in order to measure the mass of objects. By adding or removing weights to the hanger, scientists can calibrate the balance to accurately measure the mass of an object in grams or other units.
Scientists called the now separated land mass "Pangaea."
In science, mass is used instead of weight because mass is a measure of the amount of matter in an object, while weight is the force of gravity acting on an object. Mass remains constant regardless of location, while weight can vary depending on the gravitational pull. By using mass, scientists can ensure consistent measurements and comparisons across different environments.
Scientists or researchers typically measure the mass of soil in which a plant grows. This is done using tools such as weighing scales to determine the weight of the soil before and after the plant growth period. The difference in weight is used to calculate the mass of the soil in which the plant grew.
weight=mass*gravity
The physical properties used by scientists to describe all matter, sight, smell, taste, color, texture, mass, weight, volume, and density.
Scientists used to use the gram, but now the SI system is used where the kilogram is the weight unit
WEIGHT
A balance is used to measure either mass or weight. The corresponding units are kilograms (for mass) and newton (for weight).
On Earth, mass and weight are used synonymously because the gravitational force acting on an object is constant. Weight is essentially the force of gravity acting on an object's mass. Since the gravitational acceleration is approximately the same at the surface of the Earth, the terms mass and weight can be used interchangeably.
