Ch. 1 – Brief Review of Units and Measures
Start Ch. 2 – Motion in a Straight Line
Physics 2048C: A Short Introduction
We are first going to learn the classical
laws of mechanics that govern the motion
of moving bodies....
....as formulated by:
Galileo Galilei (1564-1642)
Johannes Kepler (1571-1630)
Isaac Newton (1643-1727)
This will be followed by an introduction to
wave motion and thermodynamics
These ideas may be applied to.......
Newton's laws:
From the Gatorade ad:
A.
B.
C.
"What makes bodies in motion remain in motion?"
"What makes what goes up, stay up?"
"What makes what goes down, get back up?"
One of these statements may be attributed to Newton
**The answer is A**
Newton's first law (Law of inertia): A body at rest
remains at rest, and a body in motion will remain in
motion at a constant velocity unless acted upon by an
external force.
Standing the test of time
• The classical laws of physics, including mechanics and
thermodynamics, have been rigorously studied through
centuries of experiment.
• This is the so-called "scientific method."
• During this course, we will explore many (though by no
means all**) of the classical laws of physics using
controlled experimental demonstrations.
• We will compare the results with simple mathematically
based theoretical principles.
• We will then use these theoretical principles to solve a
wide range of problems.
**PHY2049 will introduce you to more of these laws.
What do physicists do?
At the end of the 19th century, A. A. Michelson (very
famous physicist) stated that "all of the grand underlying
physical principles had been firmly established."
Then came two revolutions:
•Relativity
concepts of space and time change at large relative velocities
•Quantum mechanics
concept of matter changes on small length scales
•Classical laws of mechanics break down in these limits,
and much remains to be discovered
These are the things physicists study today through
experiment and theory, just as physicists have done
through the ages.
Physics, the 21st century, & you
A technological revolution
• 20th century microelectronics & the computer revolution
• Now we have "nanoscience“ (and molecular sciences)
Devices/molecules which are made up from just a few atoms
1 nanometer = 1 meter / 1,000,000,000
1 millionth of the diameter of a grain of rice
• Nanoscience is revolutionizing electronic and mechanical
engineering, biology, chemistry and medicine
• Physics is playing a larger and larger role in all of these
fields
However, before you can tackle these modern subjects,
you have to have a fundamental grasp of the underlying
classical laws of physics
Tips for success
•Practice, practice, practice!
•Do not fall behind in the homework.
•Do not leave preparation for exams until the last minute.
•Work on your exam technique.
•Form study groups, but do not let others do your work.
•Treat the text as a source of reference. Do not read it
cover to cover like you would a novel.
•If you are having difficulties, come and see me or the
other instructors during office hours, or by appointment
(or, as a last resort, send email) - we can help.
But, most of all....
....try to have fun!
Good luck!
