Science Performance Task Semester Review

Front

What is energy transfer?

Back

Energy transfer is the process of energy moving from one object or system to another, such as when a person lifts a book and transfers energy to it.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion, which can be increased by increasing its speed or mass.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two masses, which affects their motion and orbits, such as the gravitational pull between Neptune and its moons.

Front

What is a hypothesis in scientific research?

Back

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

Front

What is the role of coils in magnetic devices?

Back

Coils in magnetic devices create a magnetic field when an electric current passes through them, and the number of coils can affect the strength of the magnetic field.

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 a control variable?

Back

A control variable is a factor that is kept constant during an experiment to ensure that the results are due to the independent variable.

Front

What is the difference between attract and repel in magnetism?

Back

Attract refers to the force that pulls two magnetic objects together, while repel refers to the force that pushes them apart.

Front

What is a model in science?

Back

A model is a representation of an object, system, or concept that helps to explain and predict how it behaves.

Front

What is the significance of mass in gravitational force?

Back

Mass is a key factor in gravitational force; the greater the mass of an object, the stronger its gravitational pull.
