Define Acceleration

What is the rate at which velocity changes?

100

An object at rest will remain ___________ according to Newton's ________ Law. 

at rest...First 

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

Recite the formula for Newton's second law. 

Net force = Mass x 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

Direction is a necessary component to velocity, true or false

true

300

Formula for calculating acceleration

what is final speed - initial speed / time 


300

How does Inertia relate to mass? 

The greater an object's mass, the greater its inertia.  

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

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 25 meters in 2 seconds east. What is it's velocity?
12.5 m/s east (must include direction!)
400
How would you describe negative acceleration? You must use the word "velocity".
decrease in velocity over time
400

A rock with a mass of 3kg is hit with a force of 4N. What is the rock's acceleration?

N = M x A

4N = 3 kg x A

1.333333 m/s2 




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

Newton's Third Law states that ______________

for every action there is an equal and opposite reaction. 

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