A PowerPoint on the inclined plane, how it makes work easier, and examples of inclined planes and wedges.

1. Simple Machines Part 3
Inclined Planes
by Mrs. Burch

2. What do you already know about inclined
planes?

3. How do they make work easier? Is there a
trade-off?

4. Watch this video on inclined planes…

5. Investigation of planes
Watch Jarrod to see how to use your inclined plane.

7. Remember Archimedes?

8. Archimedes
invented
what we now call
the Archimedes
screw.

9. The Archimedes
screw carries water
from a low place to a
higher place.

10. These
Archimedes
screws are
at 6 Flags
Magic
Mountain.

11. These Archimedes screws are
used to drain this scummy
pond.

12. Now, you know that a screw is an inclined plane.
Watch an Archimedes screw at work…

13. Review:

14. Inclined planes make work easier because the
inclined plane is holding much of the weight.

15. The trade-off is that
you have to move the
weight over a longer
distance.

16. The flatter the inclined plane, the less force
you need to apply.

17. What are some examples of inclined planes?
