Tides
The moon is the chief contributor to the
tides. How do tides appear?
The tides
The distance to the moons center
depends on your location. The surface
near the moon is attracted with a
greater force than the center of the
Earth. The surface furthest
Gravity Business
Having recently completely mastering the Newtons law of
gravitation, Hillary has devised a new business plan. Hillary learned
that objects weigh different amounts at different distances from
Earth's center. Her plan involves buying gold b
Satellites
Satellites typically orbit ~150mile
above the surface of the Earth to avoid
friction from the atmosphere
Satellites close to the Earth complete
an orbit in 90 minutes, at higher
altitudes the velocity decreases and
the circumference of the orbi

Keplers Laws and Newton's Synthesis
Keplers laws describe planetary motion.
1.
The orbit of each planet is an ellipse, with the
Sun at one focus.
Keplers Laws and Newton's Synthesis
2. An imaginary line drawn from each planet to the
Sun sweeps out equal a
Gravitational Constant
The proportionality form of the law can be
expressed as an exact equation by introducing
a proportionality constant, the universal
gravitational constant.
F = Gm1m2/d2
G = 6.67 X 10-11 N-m2/kg2
G was first measured 150 years after N
Storage of Electric Energy
A charged capacitor stores electric energy;
the energy stored is equal to the work done
to charge the capacitor.
Storage of Electric Energy
The energy density, defined as the energy per
unit volume, is the same no matter the ori
From Newton to Einstein
General relativity or the General theory of relativity is
the geometric theory of gravitation published by Albert
Einstein in 1915/16. It unifies special relativity and
Newton's law of universal gravitation, resulting in a theory

Capacitance
A capacitor consists of two conductors
that are close but not touching. A
capacitor has the ability to store electric
charge.
