Seeing an object change positions with regards to a reference point.
What is motion?
100
Define reference point
An object that seems not to move.
100
Looking up from the planets surface what appears to move, earth or the sun?
The sun
100
= Speed * Time (how far)
What is Distance?
100
What is Velocity?
The speed an object is going plus the direction it is going
200
This is the thing whose motion you are watching
What is an object in motion?
200
What is meant when we say an object "seems" not to move
Everything technically moves, even if we don't see it
200
If you are looking at the motion of the earth in our solar system, what shape does the movement take, and what is the reference point?
a circle, the sun
200
Define Time (how long)
Distance / Speed
200
What is a change in velocity defined as?
Final Velocity - Initial Velocity
300
These are used to determine if something moves
What is a reference point?
300
The most commonly used reference point for motion
What is earth
300
If you look at the earth's motion in the galaxy, what shape does it make and what is the reference point
a corkscrew, the center of the galaxy
300
Define Speed (how fast)
Distance/Time
300
Define Acceleration
Change in Velocity/ Time
400
You can observe these things if you measure motion
What are speed, distance, time, velocity, and acceleration?
400
DAILY DOUBLE!!!
describe a situation where you would need to describe motion with regard to a reference point.
Answers may vary

What three main groups does earth belong to?
The solar system, the Milky Way galaxy, and the Local Group

If you travel 78 miles in 2 hours, what is your speed?
(describe the equation, give the answer including the unit of measurement)
78 miles/ 2 hours = 39 miles/hour
400
You are driving your car going 40 km/hr. You slam on your breaks and are now moving at 25 km/hr. What is the change in velocity?
(remember your negatives!)
25 - 40 = -15 km/hr

Describe what is moving and what the reference point could be. A bus moving down the street.
Object in motion: bus
reference point: buildings, street, lights, parked cars, etc.
500
Are reference points relevant?
Yes. If you change your position, or outlook different things will appear to be still (ex. sitting on a bus as opposed to standing outside it)
500
If you measure your change in position based on your reference point, what are you measuring (in meters)
What is distance?
500
How long will it take an airplane to land if it is traveling 4000 km at a speed of 350 km/hr?
(Include equation, answer, and unit of measurement)
4000 km/ 350 km per hour = 11.42 hours

You place a toy car on the table and wind it up. It speeds up to 3 m/s in 2 seconds. What is it's acceleration?
Change in velocity= 3 m/s - 0m/s = 3 m/s
Acceleration= 3 m/s / 2 sec. = 1.5 m/s/s
