==Key Stage 3==
===Meaning===
'''Relative motion''' is how fast an [[object]] appears to be moving when the observer is also moving.

===About Relative Motion===
: [[Object]]s can appear to be moving faster or slower if the observer is moving as well.

===Examples===
: If a van is travelling at 30m/s and a car overtakes the van at 35m/s, it appears to the van like the car was only travelling at 5m/s.
: If a truck is travelling at 20m/s towards a car which is travelling at 30m/s. It appears to the truck as if the car is travelling and 50m/s.
