About Water Resistance

Water Resistance is a contact force.
Water Resistance can only happen to an object in the water. It does not happen to objects on land, in the air or space.
The amount of water resistance depends on:
  • The size of an object.
  • The shape of an object.
  • How fast an object is moving through the water.
