Summary:

• When the force of air resistance on a falling object balances the object’s weight the object falls at a constant speed, i.e., terminal velocity.
• For a given size and shape, the object that weighs more has a higher terminal velocity.
• For a given weight, the object with the smaller surface area has a higher terminal velocity.
• For two things of similar composition and shape, the larger has a higher terminal velocity.
• Can estimate the terminal velocity as the wind speed needed to support an object’s weight.
