Air resistance is a type of friction.

• True

• False

Which of the following forces opposes motion?

• Friction

• Air Resistance

• Both friction and air resistance

• Neither friction or air resistance

The juggler replaces the balls with scarves. How would the motion of the scarves be different from the motion of the balls?

• The scarves would fall slower because they are lighter than the balls.

• The scarves would fall slower because they have more air resistance than the balls.

• The scarves will fall in the same time as the balls because gravity attracts all objects the same.
