W

hen you are riding in a car, how do you

know that the car is accelerating (that you

are going faster and faster)?

Newton’s 1st Law of Motion

A

n object at rest remains at rest, and an

object in motion remains in motion at

constant speed and in a straight line

unless acted on by an unbalanced force.

hat is the difference between mass and weight?

What SI units are used to measure mass and to measure weight?

Vocabulary

Inertia – things like to keep on doing what they are already doing

Force – a push or a pull Unbalanced Force – unequal force in

some direction that causes an object to move

Balanced Force – equal and opposite forces on an object that do not cause it to change what is it already doing

Vocabulary Weight – mass plus the pull of gravity on an

object• Measured in Newtons (N)

Mass – Amount of matter (stuff) in an object• Measured in grams (g)

Gravity– a force of attraction between 2 objects due to their masses

Friction – a force between 2 surfaces in contact with each other that opposes motion

hat are some rules that are important to follow when working with others in a group?

Write down 2 other students with whom you would like to work with in creating a roller coaster.

Science Notebook

Write down everything you do in your science notebook.

Include all measurements, drawings, ideas, and calculations.

You are responsible for keeping track of and cleaning up your materials.

Each group member must contribute.

Group rulesE

quipment Manager• Pick up supplies. Make sure all is cleaned up when finished.

ook at your speed calculation for your marble. On the half piece of graph paper, turned the long way, graph the average speed of your marble.

You should have 5 lines, one for each of your marble runs.

Agenda When you are finished, get a text

book from the cabinet by the door. We are going to practice using the

Q-notes reading technique that you learned in Panther time.

Chapter 5, Section 2, Pages 124-127.

Divide your next open page in half, the long way, like a hot dog.

Q-Notes Survey the headings and write at the top, what

you think the reading is about. Read the first red heading and change it into a

question. Write this question on the left-hand side of your page.

Read the section to answer the topic question. Look at the picture and read the caption at the

bottom of the page. Describe in your own words how the picture

fits the information you just read. Do this on the left-hand side.

Q-notes

Turn the next sub-heading (blue) into a question (right side) and write the answer (left side).

Continue writing questions and finding answers for the remainder of the chapter.

Don’t forget the pictures and captions. Summarize at bottom what the

chapter was about.

Look at the graph you did yesterday. • How far did your marble go in 1 second?• What was the speed of your marble?

• Level 2: How far would your marble go if you let it roll for 10 seconds?

Q- Notes F

inish reading the Chapter 5, Section 2.C

ontinue using the Q-Note technique.I

will be checking your notebooks for how well you follow directions and the completeness of your answers.

When you are finished, study what you wrote.

Newton’s 2nd Law of Motion

T

he acceleration of an object

depends on the mass of the

object and the amount of

force applied.

Newton’s 3rd Law of Motion

W

henever one object exerts a

force on a second object, the

second object exerts an equal

and opposite force on the first.
