Kinematics
 Kinematics is concerned with describing the way in which objects move.
Displacement
 An objects total change in position. If a man runs around an oval 400 meter
track, stopping at the precise location he began, though he ran a distance of 400 meters, his
total displacement was 0.
Dynamics
 Dynamics focuses on understanding why objects move the way they do.
Reference frame
 The coordinate system with respect to which motion is being described.
Speed
 A measure of how fast an object is moving.
Average velocity
 The timeaverage of the velocity function over a specified timeinterval.
(See formula below.)
Instantaneous velocity
 The value of the velocity function at a particular instant in time.
(See formula below.)
Gravitational acceleration
 The gravitational acceleration of objects near the earth's surface
is the same for all objects regardless of mass and is given by the number
g
= 9.8m/s
