Topics for Exam 1 - which is March 6, next Monday.

General topics for exam 1.  Be sure to review all assigned homework, blog posts and your notes.
You are permitted to have a sheet of notes for this test.  I will NOT give equations.

SI units (m, kg, s) - meanings, definitions

velocity

average vs. instantaneous velocity

acceleration

related motion problems using the formulas

speed of light (c) - approx 300,000,000 m/s

gravitational acceleration (g)

freefall problems

Newton's 3 laws - applications and problems

Kepler's 3 laws - applications and problems

epicycles

Galileo and his telescope

weight vs. mass

Weightlessness

Reference frames (recall demos)

Useful equations

Average speed:  v = d/t

Definition of acceleration:  (Vf - Vi) / t

Final speed:  Vf = a t

Distance traveled:  d = 0.5 a t^2

Newton's 2nd law (Force):  F = m a

Weight:  W = m g

Kepler's 3rd law:  a^3 = P^2
