Today we spent more time drawing vector sketches for forces in the vertical dimension. You should be getting pretty comfortable with this by now.
In-Class Work: Part I: Putting on the Brakes, Process and Procedure #5, 6
Homework: none
Learning Target: Objects in motion tend to stay in motion unless they experience a net force.
Upcoming: Measuring free falls
Today we learned about wind resistance, which increases as objects go faster. The maximum speed an object can fall is called terminal velocity.
In-Class Work: Part I: Putting on the Brakes, Process and Procedure #2,3
Homework: none
Learning Target: Objects in motion tend to stay in motion unless they experience a net force.
Upcoming: Measuring free falls
We started the Elaborate section (With or Without a Net) today. We’ll be learning what happens when forces in opposite directions do not cancel each other out, which is called a net force.
In-Class Work: Part I: Putting on the Brakes, Process and Procedure #1
Homework: none
Learning Target: Objects in motion tend to stay in motion unless they experience a net force.
Upcoming: Measuring free falls
A good bit of number crunching today, as we figured out if the initial momentum and the final momentum of the tennis balls was the same. Since we measured these value, our numbers were not perfect, but they were pretty close to being equal
In-Class Work: Part II: A Sticky Situation, Reflect and Connect, 1-5
Homework: none
Learning Target: Both elastic and inelastic collisions exhibit conservation of momentum.
Upcoming: Learning about net forces
Today we swung a velcro-covered tennis ball in to another to see what happens to momentum. Does the momentum of the single tennis ball before the collision equal the momentum of both after they stuck together? It should!
In-Class Work: Part II: A Sticky Situation, Process and Procedure #5-7
Homework: none
Learning Target: Both elastic and inelastic collisions exhibit conservation of momentum.
Upcoming: The weekend!
