Newton’s 3rd law
For every action there is an equal and opposite reaction
Newtons 1st Law
An object in motion tends to stay in motion and an object at rest tends to stay at rest unless acted upon by an unbalanced force
Newton’s 2nd Law
Force equal mass times acceleration (F=ma)
Physics
the study of various physical phenomena and the fundamental laws governing them
How were the laws of physics discovered?
through a combination of observation, experimentation and mathematical analysis.
What are the three branches of physics?
Classical mechanics
Electromagnetism
Thermodynamics
classical physics
the system of theories that dominated scientific understanding of two centuries following Isaac newtons work
Modern Physics
An effort to understand the underlaying processes of the interactions of matter using the tools of science and engineering
Base quantities
fundamental units of measurement
length (meter)
Mass (kilogram)
time (seconds)
A material to oppose the flow of electrons, changing electrical energy into thermal energy and light is called
Resistance
