Gravity and Space

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, depending on their masses and the distance between them.

Front

What happens to a feather and a hammer dropped on the Moon?

Back

Both will hit the ground at the same time because there is no atmosphere to create air resistance.

Front

What keeps planets in orbit around the Sun?

Back

Gravity is the force that keeps planets in orbit around the Sun.

Front

Does your mass change on a larger planet with more gravity?

Back

False. Your mass remains the same regardless of the gravitational pull of a planet.

Front

When does a planet move fastest in its orbit around the Sun?

Back

A planet moves fastest when it is closest to the Sun, where gravity has a stronger pull.

Front

What is the relationship between mass and gravitational pull?

Back

The greater the mass of an object, the stronger its gravitational pull.

Front

What is the effect of distance on gravitational force?

Back

The gravitational force decreases as the distance between two objects increases.

Front

What is the difference between mass and weight?

Back

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

Front

What is the gravitational pull of the Earth?

Back

The gravitational pull of the Earth is approximately 9.81 m/s².

Front

What is a black hole?

Back

A black hole is a region in space where the gravitational pull is so strong that nothing, not even light, can escape from it.
