The gravitational forces in each direction between the Earth and a sample of matter
are equal. The force exerted on the sample by the Earth is what we call the "weight"
of the sample. The force exerted by the sample on the Earth is the one that nobody
ever mentions, but it's also equal to the weight of the sample. In other words, the
weight of the sample on Earth is equal to the weight of the Earth on the sample.
Weight is a measure of the pull of gravity on a sample of matter. It is the force acting on an object due to gravity and is typically measured in units such as pounds or Newtons.
Mass measures the amount of matter in a sample.
Mass
The measure of space occupied by a sample of matter is called volume. It is generally measured in liters or cubic units, such as cubic meters or cubic centimeters, depending on the size of the sample being measured. Volume is one of the fundamental properties used to characterize matter.
The amount of space that a sample of matter occupies is called its volume. This can be measured in units such as cubic meters, liters, or cubic centimeters depending on the scale of the sample.
Yes. volume is a measure of how much space a sample of matter takes up!
The quantity of matter in an object or sample is typically described by its mass. Mass is a measure of the amount of matter in an object and is often expressed in units such as grams or kilograms. It is different from weight, which is the force exerted on an object due to gravity.
Potential energy is calculated as mass x gravity x height. Gravity is 9.8 meters per second square.
Porosity is measured by taking a sample of the soil. The sample is then tested to measure the speed of water passing through the soil.
random sample or probability sample
Yes!
Specific gravity is an intensive property. It does not depend on the amount of the substance present and remains constant regardless of the size of the sample.
