Physics first partial concepts

Measuriing

comparing a quantity to a known pre-established standart

Physical Quantities

Anything that can be measured

A magnitude has

a numerical value and a unit of measurement

Two types of Physical Quantities

Due to their origin and due to their nature

Due to their origin PHQ

Fundamental and derived

Fundamental (due to their origin) PHQ

only has one unit of measurement

Derived (due to their origin) PHQ

has two or more units of measurement

7 fundamental units

Time, mass, luminosity, distance, current, temperature and amount of substance

SI units for distance, mass and time

m, kg and s

What is scientific notation)

Method used to express more easily very small or large numbers

Due to their nature (PHQ)

Scalar and vector

Scalar (Due to their nature) PHQ

only has a magnitude

Vector (Due to their nature) PHQ

has a magnitude and a direction

Vectors (7)

Velocity, acceleration, force, impulse, momentum, displacement and electric field strength

Scalars (main 5)

speed, distance, energy work power, mass and time

Distance

total length of the path traveled

Displacement

Change in position in respective to time

what is the slope in a time-position graph?

the velocity
