A [[Water Resistance]] is a [[force]] which acts to [[decelerate]] [[object]]s that slows things down when they are moving through the [[air]]. ===About Water Resistance===: '''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''' ===Examples==={| class="wikitable"|-|[[File:WaterResistanceBoat.png|center|250px]]|[[File:WaterResistanceSubmarine.png|center|300px]]|-| style="height:20px; width:300px; text-align:center;" |As the boat moves through the [[water]] the '''water resistance''' slows it down.| style="height:20px; width:300px; text-align:center;" |The [[thrust]] of the submarine must provide a constant [[force]] to stay at the same speed because the '''water resistance''' would cause it to slow down.|}
