Physical Science Final Exam Review

Front

What is a hypothesis?

Back

A hypothesis is a testable statement that predicts the relationship between variables in an experiment.

Front

What force causes objects to fall to the ground?

Back

Gravity is the force that attracts objects toward the center of the Earth, causing them to fall.

Front

What is the independent variable in an experiment?

Back

The independent variable is the factor that is changed or manipulated by the experimenter to observe its effect.

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal and opposite, causing an object to accelerate or change direction.

Front

What is a vector quantity?

Back

A vector quantity is a physical quantity that has both magnitude and direction, such as velocity or force.

Front

What is a scalar quantity?

Back

A scalar quantity is a physical quantity that has only magnitude and no direction, such as mass or temperature.

Front

What is the scientific method?

Back

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

Front

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

Back

The control group serves as a baseline to compare the effects of the independent variable, ensuring that results are due to the variable being tested.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.
