What is speed
100
A change in position over time
What is motion
100
A car slowing down before a stop sign, for example.
What is negative acceleration
100
The type of graph that shows speed as its slope.
What is a position/distance vs time graph
100
The type of problem where units are canceled.
What is a speed triangle problem
200
167 mi/hr East
What is velocity
200
The point used to tell if something is moving/not moving or speeding up/slowing down.
What is the reference point
200
The type of graph that shows acceleration as its slope
What is a speed vs time graph
200
A slope of 0 (flat line) on a speed vs time graph
What is a graph of zero acceleration
200
The type of problem where time units never cancel.
What is an acceleration problem
300

What is 50miles/hr
300
The acceleration of our lab cars moving down their ramps.
What is constant positive acceleration
300
The equation for acceleration.
What is a=(vf-vi)/t
300
A negative (downward) slope on a distance vs time graph.
What is going back towards the reference point
300
The resolution of a ruler.
What is 1 mm
400
The velocity of a plane that travel 3000 miles east in 6 hours
What is 500 miles/hr East
400
The tool we used to make all of our lab cars gain speed.
What is a ramp.
400
The acceleration of a moose that went from 5 mi/hr to 1 mi/hr in 4 seconds.
What is -1 mi/hr/sec
400
The lab where we graphed acceleration.
What is the B4 lab or the Car Across the Floor Lab
400
∆D (change in distance)
What is Df-Di
500
The equation for average speed.
What is Vavg=(Df-Di)/(Tf-Ti)
500
Something that causes motion to begin or end.
What is a force.
500
How average speed and acceleration are different.
What is avg speed is ∆D/∆T and has units like m/s, where acceleration is ∆V/∆T and has units like m/s/s
500
The appearance of a speed vs time graph where a snake starts at rest, moves from one rat burrow to another, then swallows the residents whole and rests there for a few days.
What is a positive slope followed by a negative slope, then a slope of zero.
