breaking distance grows linerally with speed. whats the dependent variable
breaking distance
labsmart exp phase
-carry out the strategy chosen in the hypothesis phase -collect measurements in the notebook (measure the distance covered when breaking, accelerate the car to different speeds, record breaking distance at diff times)
4 phases
-hypothesis -experiment -analysis -report -final summary
which question can you ask yourself to determine the dependent variable of an experiment
which will i measure in the exp
exp phase (the heavier the ball the faster it falls)
(measure weight and falling times, drop diff balls from a fixed height)
speed
indpendent variable
what is true of the independent variable of an exp
it remains the ind var the entire exp
x axis
speed
