What is the formula for speed?
Speed = Distance / Time
100

What is the formula for velocity?

Velocity = Overall displacement / Total time of travel

100
What is the formula for acceleration?
Acceleration = Final Velocity - Initial Velocity / change in time with a direction
100
What formula is m/s an example unit?
speed or average speed
100
What can we find with a distance vs time graph?
speed of an object
200
How is speed different from velocity?
velocity needs a direction
200
What is the velocity of an object that is moving 6 meters in 2 seconds east?
3 m/s east
200
What are three ways we can tell if something is accelerating?
speeding up slowing down changing direction
200

What is m/s^2, south.. a possible unit for?

Acceleration

200
What goes on the x axis?
time
300
What is the average speed of a cow that walks east 60 meters in 90 seconds? (Remember, the units must be m/s or km/hr)
.7 m/s
300

Distance = 20 meters Time = 180 seconds Direction = south What is the velocity of this object?

0.11 m/s south

300

Final Velocity = 50 m/s south Initial Velocity = 60 m/s south Time to change velocity = 5 seconds What is the acceleration of this object?

-2 m/s squared, south

300
Which of our formulas must have a direction in order to be complete?
velocity
300
What does a distance vs time graph with a straight (linear) line indicate about a moving object?
It's moving at a constant speed
400

What is the speed of a rocket that travels 9,000 meters in 12.12 seconds?

742.60 m/s

400
An object travels 25 meters in 2 seconds east. What is it's velocity?
12.5 m/s east (must include direction!)
400

A roller coaster car rapidly picks up speed as it rolls down a slope. As it starts down the slope, its speed is 4 m/s. But 3 seconds later, at the bottom of the slope, its speed is 22 m/s. What is its acceleration?

6 m/s^2

400
For what formula would decimeters/hour east be a possible unit?
velocity
400
What does a horizontal line in a velocity graph indicate?
The object is at rest (no movement)
500

What is the speed of an object moving east for 6 seconds at 105.3 m/s?

105.3 m/s

500

What is the displacement of a runner that completes a full lap around the track? This student is trying to break Usain Bolt's Olympic record. This students runs 400 meters and ends in the same place they started, 77 seconds later. What is the displacement of the runner?

0

500

Can acceleration be negative?

Yes

500

What formula would we use if we wanted to find out how an object's velocity changed within a certain period of time?

What is Acceleration

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