Dependent variable means
the scientist controls what to test
educated guess
ask a question
what is being measured

dependent variable
independent variable
data
control group
What is a reference point?
A place or object that is staying still, that is used to determine if something else is moving.
A place or spot where something is located
The action of moving or being moved
Shortest distance between starting position and ending position
Vocabulary Check:
What is the difference between speed and velocity
Speed is based on time and velocity is not
Velocity has distance and speed does not
Speed has direction
Velocity has direction
speed =
speed x time
distance ➗ time
mass x velocity
distance ➗ speed
A speedometer shows the (a) speed of a vehicle.
In order to find the Time, you must
divide the distance by the speed (distance/speed)
multiply the distance by the speed (distance/speed)

constant velocity to the right
not moving
constant velocity to the left
Balanced
Unbalanced
Neither one
Both
