Advance Praise for Head First Physics

how to use this book

Ch. 1. think like a physicist

Ch. 2. making it all MEAN something

Ch. 3. scientific notation, area, and volume

Ch. 4. equations and graphs

Ch. 5. dealing with directions

The treasure hunt

Displacement is different from distance

Distance is a scalar; displacement is a vector

You can represent vectors using arrows

You can add vectors in any order

Question Clinic: The "Wheat from the chaff" Question

Angles measure rotations

If you can't deal with something big, break it down into smaller parts

Velocity is the 'vector version' of speed

Write units using shorthand

You need to allow for the stream's velocity too!

If you can find the stream's velocity, you can figure out the velocity for the boat

It takes the boat time to accelerate from a standing start

How do you deal with acceleration?

Vector, Angle, Velocity, Acceleration = WINNER!!!
