What is motion?
•An object is in motion
when it is
continuously
changing its position
based on a reference
point and as observed
by a person or a
device.
•Ex: A car from one
place to another…
4 General types of motion
•linear motion- straght like
example running
•angular motion- when you
rotate you hips for example
situps
•general motion- when you
use both linear and angular
motion for example cycling
going in straight lines but legs
rotating.
•projective motion- flight path.

6 types of mechanical motion
•Linear motion is the most
basic of all motions.
Uninterrupted objects will
continue to move in a straight
line indefinitely.
Linear motion is measured in
two parts. Speed, and
direction. Together these
make up the velocity.
2. Reciprocating motion is
back and forth motion.
•Rotary motion is motion in a
circle.
4. Oscillation is back and forth
motion about a pivot point.
•Intermittent motion is
motion which starts and
stops regularly.
6. Irregular motion is motion
which has no obvious pattern
to its movement.
