What is gravitational force?

Back

Gravitational force is the attraction between two objects with mass. It pulls objects toward each other, such as how the Earth pulls objects toward its center.

Front

What happens to objects when they are dropped from the same height?

Back

Objects dropped from the same height will fall at the same rate due to gravity, regardless of their mass or volume.

Front

What is an ecosystem?

Back

An ecosystem is a community of living organisms interacting with each other and their environment.

Front

What is the role of a keystone species in an ecosystem?

Back

A keystone species is a species that has a disproportionately large effect on its environment relative to its abundance. Its presence or absence can significantly impact the ecosystem.

Front

What is the impact of invasive species on native species?

Back

Invasive species can disrupt local ecosystems by outcompeting native species for resources, leading to declines in native populations.

Front

What is density?

Back

Density is the mass of an object divided by its volume. It determines whether an object will float or sink in a fluid.

Front

How does temperature affect chemical reactions?

Back

Generally, increasing temperature speeds up chemical reactions because particles move faster and collide more often.

Front

What is the difference between a star and a planet?

Back

A star is a massive, luminous sphere of plasma that generates energy through nuclear fusion, while a planet is a celestial body that orbits a star and does not produce its own light.

Front

What is the significance of the Sun in our solar system?

Back

The Sun is the central star of our solar system, providing light and heat that sustain life on Earth.

Front

What is the concept of perspective in observing objects?

Back

Perspective refers to how the position and distance of an observer affect the appearance of objects, making closer objects appear larger than those farther away.
