1.observation
2.research 3.form a hypothesis 4.experimentation 5.analyze data 6.draw a conclusion hypothesis is not supported then modify the hypothesis. |
|
control group |
Group that is not tested used for comparison to experimental group |
|
independent variable |
Factor that is changed in the experiment only one factor can be changed. |
|
dependent variable |
factor that is measured data. |
|
constants |
all the factors in both groups that stay the same |
|
data |
graphs of data can be in line or bar graphs |
|
conclusion |
must support or not support your hypothesis and based on data from your graphs. |
|
mechanics |
the study of motion of objects |
|
kinematics |
the science of describing the motion of objects using words diagrams numbers graphs and equations. |
|
scalars |
quantities that are fully described by magnitude alone |
|
vectors |
quantities that are fully described by both a magnitude and a direction |
|
distance |
a scalar quantity that refers to how far out of place an object is the objects overall change in position. |
|
displacement |
is a vector quantity that refers to how far out of place an object is the objects overall change in position. |
|
speed |
scalar quantity that refers to how fast it is measured by distance over time. |
|
distance |
a scalar quantity that refers to how much ground and object had covered during its motion |
|
displacement |
vector quantity that refers to how far out of place an object is ;it is the objects overall change in position |
|
