20 mi/hr
What is a physical measurement that contains both magnitude and directional info?
Vector quanitity
If an object is moving with a constant velocity, what do you know about its acceleration?
There is NO acceleration because there is no change in velocity
What shows acceleration on a distance-time graph?
What type of quantity is this? Scalar or vector? Speed, distance, velocity, acceleration, or NONE of these.
2.2 mm/year
Scalar and speed
A car is moving south 8 m/s on the road and another car is moving north at 10 m/s on the same road. What is the first car's relative veloicty to the second car?
18 m/s toward each other
What is the time rate of change of an object 's velocity?
Acceleration
if an object travels for 15 minutes with a constant velocity of 12 mi/h west, what is the acceleration?
There is no acceleration.
What shows constant speed on a distance-time graph?
A straight line with a slope
What type of quantity is this? Scalar or vector? Speed, distance, velocity, acceleration, or NONE of these.

What is the formula for relative velocity if the objects are moving in the same direction?
rel velocity = velocity 1 - velocity 2
What is the distance an object travels plus the direction from the starting point?
Displacement
A train takes a long time to stop. That's what makes trains so dangerous to people who cross tracks when one is near. if a train is traveling at 30 mi/h South and takes 12 minutes to come to a stop, what is the trains acceleration?
150 mi/h2 north
