Gravitational Field Quiz

What creates a gravitational field?

• The presence of a vacuum

• The motion of objects

• The presence of mass

• The energy of an object

How does the strength of a gravitational field change with distance?

• It gets stronger as distance increases

• It stays the same regardless of distance

• It gets weaker as distance increases

• It disappears once you reach space

Which of the following objects has a gravitational field?

• A planet

• A moon

• A star

• All of the above

Match the following scenarios with their effects on the gravitational field of a planet.

• If the mass of a planet were reduced to zero

• It would be cut in half

• If the mass of a planet were doubled

• It would double in strength

• If the mass of a planet was cut in half

• It would disappear

Why is the Sun’s gravitational field stronger than Earth’s?

• The Sun is much hotter

• The Sun is much larger in volume

• The Sun has more mass

• The Sun is closer to the planets

If the distance between two objects increases, what happens to the gravitational attraction between them?

• It stays the same

• It increases

• It decreases

• It disappears

What is the main difference between mass and weight?

• Mass is the force due to gravity, while weight is the amount of matter

• Mass stays the same everywhere, but weight changes depending on gravity

• Mass is measured in newtons, while weight is measured in kilograms

• Weight is a fundamental property of an object

Match the following objects with their masses on the Moon.

• A 0 kg object on Earth

• 0 kg

• A 1.6 kg object on Earth

• 6 kg

• A 6 kg object on Earth

• 1.6 kg

• A 10 kg object on Earth

• 10 kg

• 10 kg

• 30 kg

• 111 kg

• 98 N

If a cat has a mass of 4 kg on Earth, what would its weight be on Jupiter (gravity = 24.8 m/s²)?

• 9.8 N

• 99.2 N

• 24.8 N

• 992 N
