Drag is a force that acts to decelerate objects that are moving in a fluid.
About Drag
- Drag is a force so it is measured in Newtons.
- Drag is a contact force because an object must be in a fluid for drag to exist.
- When an object is moving through the air drag is called air resistance.
- When an object is moving through the water drag is called water resistance.
- Drag exists because objects moving through a fluid collide with particles in that fluid passing on some of their momentum which causes the object to lose momentum and therefore slow down.
