CSHS Year 7 Gravity, orbits and eclipses

Which of the following is a dwarf planet?

• Pluto

• Earth

• Jupiter

• the moon

Which of the following has a gravitational force field around it?

• the Earth

• the Sun

• the person sitting next to you

• Everything with mass has a gravitational force field.

As you move away from Earth, its gravitational force field:

• gets stronger.

• weakens.

• always stays the same.

• is zero

A lunar eclipse is when:

• the Moon travels around Earth in an orbit shaped like an oval.

• Earth blocks sunlight from reaching the Moon.

• the Moon blocks sunlight from reaching the Sun.

• you only see part of the Moon because of its angle to the Sun.

The diagram shows the orientation of the Earth, Sun and Moon when a spring tide occurs.The phase of the moon during a spring tide is:

• new moon.

• first quarter.

• full moon.

• last quarter.

Gravity pulls everything toward...

• The ground
• The center of mass
• The moon
• The Sun

A person would weigh less on on the Moon than on the Earth because . . .

• Moon has more mass, and therefore more gravity
• Moon has less mass, and therefore more gravity
• Moon has more mass, and therefore less gravity
• Moon has less mass and therefore less gravity

Two factors effecting the magnitude of the force of gravity between 2 objects are...

• mass and distance 
• mass and matter
• distance and weight 
• weight and mass

If Earth's mass was cut in half, what would happen to your weight?

• Increase because gravitational force increases
• decrease because gravitational force decreases
• decrease because gravitational force increases
• nothing, weight is not affected by gravitational force
