Study Notes
Mass and Weight
- Mass is a measure of the amount of matter in an object and does not change, regardless of location.
- Weight, on the other hand, measures the force of gravity acting on an object and can change depending on the gravitational field.
Weight on the Moon
- Astronauts weigh less on the moon than on Earth because the moon has a weaker gravitational field than the Earth.
Physical Properties of a Substance
- Examples of physical properties of a substance include mass, weight, volume, density, and melting point.
- These properties can be observed and measured without changing the composition of the substance.
Physical Property of an Object
- An example of a physical property of an object is its color, which can be observed and measured without changing the composition of the object.
Physical Property of Matter
- Mass is a physical property of matter, as it is a characteristic of the amount of matter in an object and can be measured.
