Booze and Pot make you Stupid!•Heavy drinking affects the hippocampus of the brain, which is involved in memory and learning.

•The short-term effects of marijuana can include problems with memory and learning; distorted perception; difficulty in thinking and problem solving; loss of coordination; and increased heart rate.

•Both booze and pot effect brain function days after you drink or smoke!

SRJC Student Guide...a successful student must dedicate 2-3 hours outside class for every hour in class. In other words, a student taking 12 units is spending 12 hours in class and 24-36 hours outside of class in order to succeed.

A full time student has a full-time job just being a student.

Schedule your time so you study/solve hw problems when you are at your mental best. Do everything else (work, shop, exercise, sleep, etc.) during your less productive times.

Learn how you Learn!

Objectives of Physics

• To find the limited number of fundamental laws that govern natural phenomena

• To use these laws to develop theories that can predict the results of future experiments

• Express the laws in the language of mathematics

• Physics explores the full spectrum of the cosmos from subatomic particles to clusters of galaxies, to the edge of space and time...

Physics 40 ISClassical Mechanics!

Study of the motion of objects and mechanical systems that are large

relative to atoms and move at speeds much slower than the speed of light.

Classical Mechanics is the basis of ALL Physics including Modern Physics.

You can’t get to Modern Physics without doing Classical Physics!

The fundamental laws and principles of Classical Physics are the basis Modern Physics.

Isaac Newton(1642 -1727)

In Principia (1687 ) Newton •Invented Calculus•3 Laws of Motion•Universal Law of Gravity

The force of gravity is Universal: The same force that makes an apple fall to Earth, causes the moon to fall around the

Earth and the planets to orbit the Sun.
