What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It is the energy that has the potential to be converted into kinetic energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and the speed at which it is moving.

Front

How can an experiment be replicated?

Back

An experiment can be replicated by following the same procedures and methods used in the original experiment to see if the same results can be achieved.

Front

Why is it important for scientists to publish detailed methods of their experiments?

Back

It is important for scientists to publish detailed methods so that other scientists can replicate their results and verify the findings.

Front

What does it mean to change variables in an experiment?

Back

Changing variables in an experiment means altering one or more factors to see how it affects the outcome of the experiment.

Front

What is the scientific method?

Back

The scientific method is a systematic process used for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.

Front

What is a hypothesis?

Back

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

Front

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

Back

A control group is used as a standard for comparison in an experiment. It does not receive the experimental treatment.

Front

What is the difference between qualitative and quantitative data?

Back

Qualitative data describes characteristics or qualities (e.g., color, texture), while quantitative data involves numerical measurements (e.g., height, weight).

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in grams or kilograms.
