This full-color, illustrated softcover book provides a highly
visual introduction to some basic astronomy concepts that everyone
should know, like explaining the phases of the moon and earth-based
evidence of the heliocentric model. There are 40 full-color pages.
The photos are NASA space photos, but NASA did not participate in
the writing or publication of this eBook. Educators may use this
material in the classroom for the purpose of teaching astronomy
concepts. Contents include our solar system, the lunar phases,
solar and lunar eclipses, seasons, the shape of the earth, and
geocentric and heliocentric models of the solar system (including
evidence for the heliocentric model).
This is book is a collection of creative physics problems, which
includes a healthy dose of calculus-based problems. No examples or
solutions are provided, as this volume of physics problems is
intended to be used in conjunction with a textbook. Like textbook
problems, answers to selected questions are provided. This can be
useful for (i) teachers who are looking for engaging problems to
assign or use as examples and (ii) diligent self-learners who are
willing to work for the answer and possibly rework the problem a
few times (which can be a rewarding strategy in the long run, but
does not suit many of today's students who want the information
simply injected into their brains). These imaginative problems are
designed to: engage the interest of students in this difficult
subject, add a little zest to abstract concepts like angular
momentum, challenge students to apply the concepts to involved
problems, and encourage students to develop and apply their
calculus skills. This includes many instructive problems that force
students to think through key concepts (like collisions where
students calculate the lost mechanical energy), problems with
conceptual questions (e.g. why a ball actually rolls farther up an
incline in the presence of friction than it does sliding without
friction), calculus-based problems (such as motion, center of mass,
and moment of inertia), and review problems grouped by a theme
(such as one about a chimp who stole physics a la the Grinch).
Involved problems are included to build fluency in the major
problem-solving strategies, like combining conservation of energy
and momentum. Many problems are broken down into parts to help
guide students along - that is, you can check your answer to part
(a) before moving onto part (b)
