The ABCD model for writing objectives
Introduction
Objectives will include 4 distinct components: Audience, Behavior,
Condition and Degree.
Objectives must be both observable and measurable to be effective.

History
Russian scientist Dmitri Mendeleev
taught chemistry in terms of
properties.
Mid 1800 - molar masses of elements
were known.
Wrote down the elements in order of
increasing mass.
Found a pattern of rep

Stopping Distance
To reduce the kinetic energy to zero:
so the stopping distance is
Note that this implies a stopping distance independent of vehicle
mass. It also implies a quadrupling of stopping distance with a
doubling of vehicle speed.

Machines
A machine is a device used to multiply
forces or change the direction of force.
three simple machines are ramps, levers,
and pulleys.
Ramps
A ramp is a simple machine it allows one
to move an object up without exerting the
force necessary to lift
Levers
The fulcrum is the pivot point of the lever, there are three basic
types of levers.
In all three cases the mechanical advantage is the ratio of the
distance to the fulcrum where force is applied to the distance from
the load to the fulcrum. Note th

Kinetic Energy, and the Work-Energy Principle
If we write the acceleration in terms of the velocity and the distance, we find that
the work done here is
We define the kinetic energy:

Energy transformation in a simple
pendulum
Kinetic energy is maximum at the bottom of
the pendulums arc
Potential energy is highest at the top of the
