What is an Independent Variable?

Back

The one factor that a scientist changes during an experiment.

Front

What is a Dependent Variable?

Back

The factor that is measured or observed in an experiment, which changes in response to the independent variable.

Factors that are kept constant throughout an experiment to ensure that the results are valid.

Front

What is the formula for speed?

Back

Speed = Distance / Time.

Front

What is Net Force?

Back

The sum of all the forces acting upon an object.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is the purpose of a control group in an experiment?

Back

To provide a baseline for comparison against the experimental group.

Front

What is the scientific method?

Back

A systematic process for conducting experiments and making observations to answer questions.

Front

What is the significance of repeatability in scientific experiments?

Back

It ensures that results can be consistently reproduced under the same conditions.

Front

What is the role of hypothesis in an experiment?

Back

A hypothesis is a testable prediction about the relationship between variables.
