Air resistance
Terminal velocity
Slide 1 - Slide
Goals
Describe air resistance and its effect on motion.
Name ways to reduce and increase air resistance.
Explain the fall of a skydiver in terms of speed and air resistance.
Slide 2 - Slide
An experiment
Slide 3 - Slide
Experiment
Predict which one will hit the floor first. Explain.
Drop both from the same height at the same time. Observe what happens.
Which actually hit the floor first?
How can you explain the difference in falling speed?

Slide 6 - Slide
Describe air resistance in your own words
Slide 7 - Open question
Air resisting the motion
of an object.
Slide 8 - Slide
Give 3 examples of situations where you can see, feel or hear air resistance.
Slide 9 - Open question
Slide 10 - Slide
How does air resistance effect you when you cycle?
Slide 11 - Open question
It makes you speed up at a slower rate.
It causes you to reach a lower final speed.
Slide 12 - Slide
How does the speed you travel at effect air resistance?
Slide 13 - Open question
The faster you travel,
the greater the air resistance.
Slide 14 - Slide
Important
Air resistance makes you speed up at a slower rate.
Speeding up increases air resistance.
