100
Kortney runs a 50 meter dash. What is her total distance?
50 meters
100
What is the formula for speed?
Distance/time
100
What are the two ways we express changing speed?
Average and Instantaneous speed
100
What is Distance?
How far a person/object travels.
100
What is Instantaneous speed?
The speed of an object at a give point in time.
200
You walk outside and see the mail truck at your neighbor's house. You go back inside and when you come out again you see the mail truck has moved to your house. Has motion occurred? How do you know?
You know motion occurred because you had a reference point to where the truck was before.
200
What are the units for the speed formula?
Meters/seconds
200
What is a good example of instantaneous speed?
Speedometer
200
What is displacement?
The distance and direction of an objects change in position.
200
What is motion?
A change in an objects position relative to a reference point
300
Kortney runs 50 meters North, then turns around and runs 20 meters south. What is her displacement?
30 Meters north
300
A passenger elevator travels from the first floor to the 60th floor, a distance of 210 meters, in 35 seconds. What is the elevators speed?
210meters/35 seconds = 6meters/second
300
Emma is trying to add 15 meters West + 15 meters South. Why can't she add these values?
We can't do calculations for velocity, momentum, or acceleration when we have two or more directions.
300
What is a reference point?
A basis for standard or evaluation
300
What is Average Speed?
The total distance traveled divided by the total time of travel
400
50 Meters North plus 35 meters south = ?
15 meters North
400
Speed can be graphed using what mathematical concept?
Slope
400
Why would a storm appear to be moving slower if you are traveling in the same direction as it?
Your relative motion is similar to the Storms
400
What is Velocity?
The distance an object travels divided by the time plus a directional coordinate.
400
What is Speed?
the distance an object travels per unit of time
500
Veronica travels 30 meters east, then travels 45 meters north, then travels 15 meters west. What is her distance traveled and her displacement?
Total Distance = 90 meters
Total displacement = 15meters East, 45 meters north
500
An object moving at 30meters/second traveled a total of 150meters. How long was the object traveling?
150meters/30meter per second = 5 seconds.
500
What is an example of something that is moving so slowly that you cannot detect its motion, but you can see evidence of it over a long period of time?
Continents moving on tectonic plates, Earth revolving around the sun, Earth spinning (day and night cycle)
500
What is Momemtum?
A measure of an objects velocity multiplied by the objects mass.
500
What is Acceleration?
The rate of change of velocity.
