12-1 Newtons Law of Universal Gravitation
Newtons insight:
The force accelerating an apple downward is
the same force that keeps the Moon in its orbit.
Hence, Universal Gravitation.

8-1 Conservative and Nonconservative
Forces
Conservative force: the work it does is stored in
the form of energy that can be released at a later
time
Example of a conservative force: gravity

1-1 Physics and the Laws of Nature
Physics: the study of the fundamental laws of nature
these laws can be expressed as mathematical equations
much complexity can arise from relatively simple laws

Before describing motion, you must set up a
coordinate system define an origin and a
positive direction.

5-1 Force and Mass
A force is something that is capable of changing an
objects state of motion, that is, changing its velocity.
Force is a vector it has magnitude and
direction

9-1 Linear Momentum
Momentum is a vector; its direction is the
same as the direction of the velocity.
Momentum is a measure of how hard it is to
stop an moving object.

From experience, we know that the same force
will be much more effective at rotating an
object such as a nut or a door if our hand is not
too close to the axis.
This is why we have

If velocity is
constant,
motion is along
a straight line:
