Question 3

Who was Isaac Newton and what did he discover?

Answer 3

Isaac Newton is a mathematician and a physician and he discovered the 3 laws of motion and the gravitation of the apple.

Question 4

How does mass affect gravitational pull?

Answer 4

The more matter an object has, the stronger its gravitational pull.

Question 5

What does the earth do in one day?

Answer 5

the earth rotates in 24hrs

Question 6

What does the earth do in one year?

Answer 6

The earth takes 365 days to complete one orbit.

Question 7

What is Gravity?

Answer 7

Gravity is the force of attraction between two objects.

Question 8

What is Weight?

Answer 8

Weight is the force of gravity acting on an object.

Question 9

What is Mass?

Answer 9

Mass is the amount of matter in an object and it always stays the same.

Question 10

How do you find the the weight of an object?

Answer 10

Weight = Mass x Gravity.

Question 11

How does the moon create the tides?

Answer 11

The moon creates the tides by gravitational pull.

Question 12

What is Geothermal energy and how is it made?

Answer 12

• Geothermal energy comes from the heat beneath the earth’s surface.
• The magma under the earth’s surface heats the layer of rocks above and below and some of it is released as steam.
• Then the steam can be used to turn a turbine in a generator, producing electricity.

Question 13

Explain the key characteristic of a non-renewable resource?

Answer 13

• Cannot be regenerated easily
• Have solids, liquids or gases
• Remain as waste in some other form after there use unless there are subjected to recycling.

Question 14

Describe the difference between mass and weight?

Answer 14

• Weight is a measurement of the gravitational pull on an object
• mass is the term used to describe how many particles or atoms make up an object.

Question 15

What is the difference between renewable and non renewable resources?

Answer 15

• Renewable resources are resources that can be renewed within a lifetime
• non renewable resources take a long time to form or cannot be formed again.

Question 16

How the position of the moon and sun affect the size of the tide on Earth?

Answer 16

The gravity of the moon affects the tides. Low tides happened between each high tide. High tides happen every 12 hours.

Question 17

What are the phases of the moon?

Answer 17

New moon, waning crescent, waning quarter moon, waning gibbous, full moon, waxing gibbous, waxing quarter moon and waxing crescent.

Question 18

Why is it important

to use resource sustainability?

Answer 18

The environmental quality in order to have healthy communities clean air.

Question 19

can you calculate weight given the mass of an object and the gravitational force?

Answer 19

You can calculate it a mass x gravity

Question 20

What is solar energy and how is it made?

Answer 20

Solar energy is energy from the sun that is converted into thermal or electrical energy and it is made when solar cells convert sunlight into electrical energy

Question 21

What is Hydroelectric energy and how is it made?

Answer 21

Hydroelectric energy is produced by falling water that turns turbines to produce electricity and the water supply is held in dams and then released to cause fast-flowing water, which turns the turbines efficiently.

Question 22

What is the difference between a solar and lunar eclipse?

Answer 22

• The lunar eclipse is when the moon is in Earth’s shadow and appears dark
• the solar eclipse is when the light from the sun is blocked by the moon.
