Drag Force

Open Ended

Journal - Chop Wood Carry Water

Drag Force

• All the particles in the air around an object exert forces on that object

• Air actually exerts huge forces, but in most cases it is balanced on all sides, so it creates a net force of zero.

Open Ended

Give an example to help prove that air can exert a force.

Drag Force

• The force exerted by a FLUID on an object opposing motion through the fluid.

What properties effect drag force?

• The motion of the object

• The properties of the object

• The properties of the fluid

Terminal Velocity

The constant velocity that is reached when the drag force equals the force of gravity
