===Meaning===
[[Water Resistance]] is a [[force]] which acts to [[decelerate]] [[object]]s that are moving through the [[airwater]].
===About Water Resistance===
: '''Water resistance''' increases with [[speed]]. The faster you travel the greater the '''water resistance'''.
: '''Water resistance''' depends on the [[Surface Area|surface area]] facing the direction of motion. The bigger the [[Surface Area|surface area]], the larger the '''water resistance'''

===Meaning===
[[Water Resistance]] is a [[force]] which acts to [[decelerate]] [[object]]s that are moving through the [[water]].
===About Water Resistance===
: '''Water resistance''' is a [[force]] so it is [[Measure|measured]] in [[Newton]]s.
: '''Water resistance''' is a [[Contact Force|contact force]] because it can only exist when an [[object]] is moving in the [[water]].
: '''Water resistance''' increases with [[speed]]. The faster you travel the greater the '''water resistance'''.
: '''Water resistance''' depends on the [[Surface Area|surface area]] facing the direction of motion. The bigger the [[Surface Area|surface area]], the larger the '''water resistance'''
: '''Water resistance''' exists because [[object]]s moving through [[water]] [[collide]] with the [[water]] [[molecule]]s passing on some of its [[momentum]] which causes the [[object]] to lose [[momentum]] and therefore slow down.
