|
|
|
does everything move? example: if a book is on resting on a desk is it moving and if yes how fast?
|
yes it is relative to the sun.
yes, 30 km/s |
|

|
|
speed=
|
distance/time
|
|
|
what are some unit measures of speed?
|
m/h km/h m/s
|
|
|
acceleration=
|
change in velocity/ time
|
|
|
define good acceleration
|
is change in velocity in faster time
|
|
|
does direction change affect the acceleration? why?
|
yes because when you change direction it affects the velocity which affects acceleration
