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
