The speed that shows up on the speedometer on a car is known as what?
Instantaneous speed
What is the difference between distance and displacement?
Displacement is how far an object is from the starting point and includes the direction
What does the slope on a velocity vs. time graph tell you?
Rate of change in velocity is known as
Acceleration
This is calculated when you take the total distance traveled and divide by the total time.
Speed
The slope on a distance vs. time graph tells you
Speed
A rocket moving at a speed of 710 m/s can travel very far in 15 seconds. Determine how far.
10,650 m
This describes an object’s speed and direction
Velocity
What does it mean if an object has a negative acceleration?
It is slowing down
Show the difference between how a distance vs. time and a velocity vs. time graph show an object that is speeding up.
D vs. T graph is curved
V vs. T graph is straight
Sketch a distance vs. time graph of an object that is not moving.
X- Time
Y- Distance
Straight line at any point on the y-axis
A runner jogs 60 m on a track towards the finish line, then turns and runs back 20 m. What is her distance and her displacement?
Distance = 80 m
Displacement = 40 m towards the finish line

-5.43 m/s2
Show the difference between how a distance vs. time and a velocity vs. time graph show an object that is slowing down.
D vs. T is curving down
V vs. T is a straight line down
