Projectiles, Part 2

Assuming that you can throw all objects at a speed of 3 m/s, what effect will a changing angle have on the distance a projectile travels?

What about a changing mass?

Projectile Motion

Everytime we launch something into the air, it has properties of a projectile. Today we will be studying the properties of projectiles here

When you get done, tell me what you have learned about

a) angle patterns

b) object shape patterns

c) object shape patterns with resistance

You may work with a partner, but the blog post must be done individually.

Explaining a Newton to someone (10 pts)

A common quarter pounder weighs about 200g, with bun, or about 2N. 10 N is about 2.2 pounds. Come up with a scale of common objects that are an example of

1 N (.1 kg)

10 N (1 kg)


100 N

1000 N

10000 N

Football isn't always Football

Ask a European what football is and you can get tons of answers! Just check here for a look.

Pick one type of football (rugby, soccer, American Football, Aussie Football) or some ancient version and give me an example of when you would find inertia, a mass vs. acceleration relationship, a mass vs. force relationship, and a force vs. acceleration relationship. Explain two different frames of reference from which you can watch the game.

Forces around us

What variables affect the strength of a force? Consider forces in balance and forces not in balance. Are they the same or different?

Happy Early Out!

Well, guys, tomorrow is the first test. You need to spend at least a half hour studying. The test will include 10-15 multiple choice, and 3-5 short answer. I do not ask for vocabulary word definitions (that matching section), but I do use the vocabulary in the questions to help you think.

Topics covered on the test include:
reaction time
stopping distance (double the speed, increase stopping time by 4)
yellow light factors
what a d-t graph looks like for constant speed, acceleration, deceleration, and no motion.
strobe photos
how to avoid road hazards
equipment conditions
the questions in these blog posts...


Have a great day!

BM 2 Final Reflection

Write a 2-3 paragraph summary of what you have learned in this project about driving safety, and the factors affecting individual drivers. This should be a separate comment on the blog for each student. It should show me, without defining a list of vocabulary words, that you know what it means for a car or a person to experience velocity, speed, acceleration, reaction time factors, centripetal force, inertia, and equipment condition.

Please hand in the graph from part 1, the poster from page 2 (if you did it), your conclusions from page 3, and your conclusions from page 4.
