What is force?
Push or pull
>⚓<
The ship is facing to the right and the arrows are the forces applied. If the ship is at rest, what change in motion would the ship experience?
It will stay at rest.
Click the link above. Is this a 1 or 2 object model?
2 object model.
You push on the wall and neither you and the wall moves. Why?
Because the forces are balanced.
What is Newton's 1st law?
Object at rest stays at rest and object at motion stays in motion unless an outside force is applied.
What is mass?
The amount of matter in an object

The ship is facing to the right and the arrows are the forces applied. If the ship is at rest, what change in motion would the ship experience?
It will sink.
Click the link above. Is this 1 or 2 object model?
1 object model.
You let go of a pencil and it drops down to the floor. Why?
Because there's gravity.
What is Newton's 2nd law?
Speed= Mass x Acceleration
What is criteria?
Something you want, doesn't necessarily need to be there for something to work
>>>⚓<
The ship is facing to the right and the arrows are the forces applied. If the ship is moving, what change in motion would the ship experience?
It will keep accelerating(speeding up).
What are the arrows called in the model?
Vectors
You put a book on a table and it stays on the table(it doesn't fall through it). Why?
Because the table's pushing back with the same force.
What is Newton's 3rd law?
Every action has an equal and opposite reaction.
True or False;
Something that is accelerating is ONLY speeding up.
False. It's any change in motion due to the object's changing speed. You can also say it's decelerating for something that's slowing down
>⚓<
The ship is facing to the right and the arrows are the forces applied. If the ship is moving, what change in motion would the ship experience?
It will keep moving in the same speed and direction.
What do vectors show?
Magnitude/Direction

Which would move farther? Why?
The ping pong ball because it has less mass than the basketball.
Whych direction does friction occur?
The opposite direction the object is moving.
What is the difference between stable and balanced?
They're the same thing

The ship is facing to the right and the arrows are the forces applied. If the ship is at rest, what change in motion would the ship experience?
It will move backwards.
True or false- 2 object models show motion.
False

Which will move farther? Why?
There's not enough information to determine.We need the mass of all the balls.
Dependent Variable depends on _______.
Independent variable.
