Measurement Flashcards
What is Mass?
A measure of the amount of an object present. # of stuff
What is Accuracy & Precision?
Accuracy is how close a given value is to the true value.
Precision is how close each measurement is to the next.
What is weight?
A measure of the force of gravity on an object.
What is length?
A measure of how much an object spans.
What is volume?
The amount of space matter occupies.
What is temperature?
A measure of average kinetic energy amongst a objects particles.
Kelvin
Celsius
Fahrenheit
Density is…….
Amount of matter per unit of volume.
D= M/V
What is pressure?

Force is___ ______ __ ____ __ ____ __ __ ______
The amount of push or pull on an object.
Energy is?
The measure of ability to do work or generate heat.
Physical proprieties can be categorized into 2 areas. These areas are?
Extrinsic Proprieties-Proprieties that change based on the amount of substance present.
Mass, Volume, Etc.
Intrinsic Proprieties-Proprieties that do not change based on how much of an object there is. Density is a good example.
