2. Linear Motion Motion is easy to recognize but can be hard to describe
The following quantities are used to describe motion: speed, velocity and acceleration
Each of these is a rate. A rate is a quantity divided by time.
Motion along a straight line is sometimes called linear motion.
3. All Motion is relative All motion is relative to a reference.
This means that we describe motion of an object relative to some other object
In our environment, the reference for motion is the earths surface, and speeds are measured relative to the earth
The earth moves at 107,000 km/h relative to the sun
4. Speed Speed is a measure of how fast something is moving. It is the rate at which a distance is covered Units of speed could be: km/h, m/s, mi/h, ft/s In physics we use units of m/s for speed s = d/t
