mass is a measure of the space an object takes up.
The sun, the stars.
they used a seismograph
Mass is the attribute of an object that is a measure of the object's inertia. It represents the amount of matter in an object and is a measure of how much an object resists changes in its motion.
"What do you measure (when) you measure..." ? When you measure an object's temperature, you are measuring the amount of heat the object emits (gives off). There is no such thing as cold, only the absence of heat.
degrees Temperature is a measure of heat in an object.
Temperature is a measure of the average kinetic energy per molecule in an object. It is not a measure of the total kinetic energy of all the molecules in the object.
mass, which is a measure of the amount of substance present in an object. This measure is independent of the object's location or surroundings.
they checked it by checking the position of the planets.
When you measure an object's temperature, you are measuring the average kinetic energy of the molecules in the object. This is typically done using a thermometer to quantify how hot or cold the object is.
Area is the measure of how much surface an object has.
The object's weight is the measure of the gravitational force on that object.
