measurement of distance an object travels per unit of time (seconds/minutes)
how fast an object moves
100
Define displacement
difference between the first and final position of an object
100
What is the difference between distance and displacement?
Distance is the measurement between two points
Displacement is the difference between the starting and finishing point of an object
200
What is an independent variable?
The part of an experiment that's being changed

what is constant speed?
the rate in which an object is moving at the same speed.
200
Define dimension
distance or length measured in one direction
200
Solve for the acceleration:
Mary was walking for 5 seconds. She started off walking 10 m/s and ended up walking 20 m/s, what is her rate of acceleration?
2 m/s

What is the purpose of a control?
To compare/ remain unchanged

what is the equation to determine the average speed?
Average speed (in m/s): total distance (in m)
total time (in s)

Define position:
an object’s distance and direction from reference point.
