Lesson 2
What do we draw/us to show force.
We us vectors.
Is there a force holding us down and if there is what is it.
Yes, and it is gravity.
What is the meaning of a fair investigation.
It means that everything is misheard and has more than one trial.
what happened in the phone case video.
He dropped the phone case from different Hights and with no phone case.
A water bottle on a table is it balanced or unbalanced.
It is balanced.
What shows direction and magnitude.
We us vectors
What did we learn when we pushed a wall.
We learned that we have the same force as the wall.
What is the meaning of acceleration.
To change in motion/speed.
Was this a fair investigation.
No because he didn't meshier the Hights and the phone4 landed in different places and parts.
Me pushing a table to the ground balanced or unbalanced.
It is unbalanced.
What problem did we have in this activity/lesson.
We had to make a cheap phone case and easy axes to the phone.
What do we call when forces are the same.
It is a balanced force.
What is the meaning of constant motion.
An object that dose not change in motion or not changing in speed.
Dose this teach us if a case is better to us and show us how much better it is to have one.
Yes and no,a case is better, but we don't know how much better.
When I push a wall and don't move balanced or unbalanced
It is balanced.
What was the criteria in this lesson.
To protect a phone with minimal resorces and that is cheap and easy axes.
What do we call when forces are not the same.
We call it unbalanced forces.
What is an independent variable.
The thing that we are investigating changing or testing.
What fetcher seems to influence withe or not the phone will brake.
If the case is on or not
a ball hitting another ball and making it fly balanced or unbalanced.
It is unbalanced.
What activity did we do in this lesson.
We did touch a wall.
What activity did we do in this lesson.
We did touch a wall.
What is a dependent variable.
The results of the thing I change.
Changes to make it more reliable.
We could mishear everything.
a tower on a table that has a book on top of the tower and is moving balanced or unbalanced.
It is unbalanced.
