Explain the process of measurement and describe the three basic parts of a quantity. Describe the properties and units of length, mass, volume, density, temperature, and time. Recognize the common unit prefixes and use them to describe the magnitude of a measurement. Describe and calculate the density of a substance.
The weight of an object is determined by the force that gravitation exerts upon the object. The weight is equal to the mass of the object times the local acceleration of gravity. Thus, on the Earth, weight is determined by the force of attraction between the object and the Earth.
25 sie 2020 · The difference between mass and weight is the mass is a measure of the amount of matter in an object, while weight is a measure of the effect of gravity on that mass. In other words, gravity causes a mass to have weight.
