Counting Atoms/Conservation Mass

100

how many hydrogen atoms are there here?

2

ok how many oxygen?

200

how many Hydrogen on the reactant side?

Does this follow the law of conservation of mass?

4

yes it follows it!

300

how many total atoms are there?

24

400

NaCl is the chemical formula for salt. Is NaCl considered a compound or an element?

Compound*

ok, so is Cl a compound or element?

500

______ g of hydrogen reacts with 32 g of oxygen to produce 34 g of hydrogen peroxide.

2

Ok good job so what is the law of conservation of mass about?

Plate Tectonics

100

what is this super continent called?

PANGAEA

Good job!

What is the evidence of this?

200

What phenomenon occurs when the denser oceanic lithosphere sinks beneath a less dense continental lithosphere at a convergent boundary?

Subduction!!!!!

300

The model shows two continental plates. The folded mountains in this model form at which type of plate boundary?

Convergent!

Ok ok ok soooooooo' name some other geographical features colliding plates create?

400

what type of boundary creates a new sea floor?

Divergent 

what are other geographical features dividing plates create?

This is all from convection right? 

Describe convection!

500

The image shows a plate boundary. Arrows have been added to indicate the movement of the plates.

What plate boundary feature is also shown?

A fault forming at an active transform boundary

What will movement at a fault cause to occur?

Newtons Laws

100

What is the unit of measurement for force?

Newtons (N)

great so what is the unit for acceleration 

200

Newton's ________ Law states that objects in motion tend to stay in motion, and objects at rest tend to stay at rest unless acted upon by an outside force.

First 

also known as law of what?

300

You are carrying a lunch tray when you bump into the edge of a table. Although the tray did not tip, your milk falls off of the front of the tray. What law is that?

FIRST 

400

When you are running. your foot exerts force on the ground and the ground exerts force back onto you. Which of Newton's laws is represented?

Third 

Action Reaction right?

500

Think about pushing a shopping cart and a car. If you apply the same amount of force to both, the shopping cart will travel fast, but the car will hardly move. To move the car you would need a larger force. Which of Newton's laws is being represented?

Second 

Net Force

100

If there are two forces going in the same direction how would you find the net force?

Add

200

if these guys are pulling with the same force what will happen?

They ain't movin' nowhere at all!

300

What is the Net Force?

40N to the right 

400

What is the Net force?

20N to the right 

500

is this balanced or unbalanced?

Unbalanced OK Buddy is it moving or not moving?

Newtons 2nd law

100

What is the formula to calculate force?

F=MA ( Mass multiplied by Acceleration ) 

200

How much force is needed to accelerate a 2 kg physics book to an acceleration of 6 m/s/s?

12N

300

You pull horizontally on a 50-kg crate with a force of 500 N, and the friction force on the crate is 250 N. The acceleration of the crate is (find net force, use formula)

Hint 50 or 10 or  5

5 m/s

400

A force of 90N is applied to each cart below, which one will accelerate the fastest?

number 1
