What is the formula for speed?
Speed = Distance / Time
100
What is the formula for velocity?
Velocity = Distance(displacement) / Time with a direction

displacement

100

Which word is "how far you travel in total"?

distance

100

What goes on the y-axis of a distance vs. time graph?

distance

200
How is speed different from velocity?
velocity needs a direction
200

What is the velocity of an object that is moving 6 meters east in 2 seconds?

3 m/s east

200
How can we tell if an object is accelerating? Name the 3 ways.
speeding up (increasing speed) slowing down (decelerating) changing direction (turning)

Phillip walked 4 laps around the classroom that were 20 meters each.  What was his distance?

80 meters

200

In a distance vs. time graph, what goes on the horizontal x-axis?

x-axis is time

300
Name units often used for expressing speed.
miles/hours (mi/hr), meters/second (m/s), kilometers/hour (km/hr)
300
Distance = 20 meters Time = 4 seconds Direction = south What is the velocity of this object?
5 m/s south
300
Can an object accelerate if it is moving at a constant speed?
yes, it can change direction (ex: carousel moving at a constant speed)

Phillip walked 4 laps around the classroom that were 20 meters each.  What was his displacement?

zero meters

300
What does an angled line on a distance vs. time graph indicate about an object?
It's moving at a constant speed.
400
A porcupine moved toward a pond at a speed of 5 m/s. It took him 8 seconds. What was the distance he traveled?
40 meters
400

An object travels 30 meters in 2 seconds east. What is it's velocity?

15 m/s east (must include direction!)

400

Name the units for displacement.

meters

400

Name units used for velocity.

Km/hr, m/s, mi/hr - with a direction! Must have a direction with unit!

400
What does a horizontal line in a distance vs. time graph indicate?
The object is at rest (no movement)
500

What is the speed of an object traveling 100 meters in 20 seconds?

5 m/s

500

Calculate the velocity of a mountain climber if that climber is moving northeast at a pace of 6 km in 2 hours?

3 km/hr northeast

500

What vocabulary term is "the rate of change in velocity"?

acceleration

500

How can you find distance if you are given speed and time traveled?

speed times time

500
What does a horizontal line on an speed vs. time graph indicate?
The object is traveling at a same (constant) velocity.
