INCLINED PLANE
INCLINED PLANE : An inclined plane is a simple machine with no moving
parts. It is simply a straight slanted surface. ( Ex. a ramp.)
ACTIVITY: What happens to the amount of work needed to
move a resistance
when the distance of the inclined plane increases?
Materials:
spring scale
weight
ruler (1ft)
shoebox
yardstick
1. Place the shoebox on a tabletop.
2. Place one end of the ruler on top of the shoebox and the other end of
the ruler on
the tabletop.
3. Put the weight on the lower end of the ruler.
4. Attach the spring scale to the weight.
5. Slowly move the weight up the inclined plane to rest on the top of the
shoebox.
6. Read the spring scale as you move the weight.
7. Next replace the foot ruler with the yardstick.
8. Repeat steps 2 - 7.
