100

The EXACT place where an object is

(Location)

What is POSITION?

100

How figure skaters use science to control their spins

SLOW spin: Arms OUT wide

FAST spin: Arms CLOSE to her body or STRAIGHT UP

100
A weight hanging from a string

What is a PENDULUM?

100

What is a tension force?

PULLING force that STRETCHES something


100

Force that pulls two objects toward each other

What is GRAVITY?

200

Some words that describe the position of an object

What are

1. TO THE RIGHT OF

2. BEHIND

3. ABOVE

200

What can you learn when you observe patterns of motion

What is PREDICT how an object WILL MOVE?

200

Weight

BOB

200

What is a spring force?

When an object that has been stretched SNAPS BACK into original position

200

What happens when forces are balanced?

Balanced forces are EQUAL and the object WON'T MOVE
300

The WAY and object FACES

What is DIRECTION?

300

To tell what WILL HAPPEN in the FUTURE

What is PREDICT?

300

What are contact forces?

Forces between objects that are TOUCHING

300

What is friction?

Stopping force

Goes against the motion of an object

300

What happens when forces are unbalanced?

Unbalanced forces are NOT EQUAL and the object will move in the direction of the LARGEST FORCE.

400

The position of an object COMPARED TO the position of ANOTHER OBJECT

What is RELATIVE POSITION?

400

Example of a pattern of motion that is EASY to SEE

1. Playground swing moves BACK AND FORTH

2. Seesaw goes UP AND DOWN

400

A push or a pull

What is a FORCE?

400

What are noncontact forces?

Cause a push or pull on an object WITHOUT TOUCHING it

400
The SUM of forces acting on an object

What is NET FORCE?

500

CHANGE in POSITION

What is MOTION?

500

Pattern of motion that is harder to see

Sound speakers on a TV move BACK AND FORTH
(Vibrate)

500

What does it mean to EXERT?

PUT A FORCE

500

Three noncontact forces

1. Gravity

2. Electricity

3. Magnetism

500

A math problem

1N + 1N = 2N

1N + -1N = 0

What is an EQUATION?

600
How FAR something travels

(1,000 miles away)

What is DISTANCE?

600

Examples of how motion can CHANGE

1. SPEED UP


2. SLOW DOWN

3. CHANGE DIRECTION

600

How does force affect the motion of an object?

1. START / STOP

2. CHANGE DIRECTION

3. CHANGE SPEED

600

A force that can exert a pull on objects such as IRON

What is MAGNETISM?

600

What happens when there is a net force of 0?

Forces are BALANCED and there is NO MOVEMENT

700

The measure of HOW FAST or HOW SLOW an object moves

(55 miles per hour)

What is SPEED?

700

What happens when an object doesn't follow a pattern

Motion can be VERY HARD to PREDICT

700

How does the length of string affect the amount of time the pendulum swing?


The LONGER the STRING the
LONGER the pendulum will SWING

700

How do maglev trains work?

MAGnet & LEVitation

POWERFUL MAGNETS cause trains to float above a track and move forward.

800

What did we learn about motion in our ping pong ball and golf ball experiments?

An object at ___ stays at ___

An object in ___ stays in ___

An object at REST stays at REST

An object in MOTION stays in MOTION

until it's acted upon by an unbalanced force

800

What happens when two objects of the same shape are dropped from the same height at the same time?

MOON: They will hit the ground at the SAME TIME.
