1 For physics class, Jada wants to know how the surface of different ramps
affects the maximum speed of a marble being rolled down the ramp. To
study this, she compares the maximum speed of a marble rolled down
ramps with different surfaces. She rolls the same marble down each type
of ramp 10 times. What type of study is this? *
O Survey
Observational study
O Experimental study

The correct option is;

Experimental study

Step-by-step explanation:

We note that an observational study is one where the person who carries out the study only puts together data or observes the effect of a factor, an intervention or a test and comes to conclusion based on what is observed without trying to control the variables while an experiment involves the application of an intervention to the group and taking down the effects.

The conditions of the study is directly under the influence of the researcher in an experiment such that the cause and effect relationship of an event can clearly be proved

Therefore, Jada is performing an experimental study.
