Safe Landings
FORCE & ACCELERATION
NEWTON’S 2ND LAW
How did the Standard Deviation Bars on your graph affect the confidence you
had in your experimental results?
Why? (Explain)
ENTRY TASK:
Note: Entry Tasks
are 10% of your
grade
Vector Addition Practice & Article Summary
Speed Bumps Conclusion
Questions?
HAVE OUT
What are some things skydivers do to reduce the force
they feel when they land?
Middle Column:Review what you know about the size and
direction of forces when two objects interact.
Far Right Column:Use Vector Sketches and labels to PREDICT the
size of the forces you will feel in each scenario relative to just standing still on the ground
MAKE PREDICTIONS
DO NOT injure yourself for Science.
CAUTION!!!
Discuss what you felt
THEN
Record your results using words (middle column)AND
Vector sketches w/ labels (far right column)
EXPERIMENT!!!
Review what we have learned about forces so far by completing each force related statement using the
words or symbols in the box
We will discuss this in 5-ish minutes
FORCES CONCEPTS REVIEW
Safe Landings Conclusion
