6
Q

What does gravitational force depend on?

A

The masses of objects ( when the mass increases, force increases)
The distance between the objects ( as the distance between the masses increases, the force decreases)

Q

How do systems become stable?

A

They become stable by changing (=processes)

17
Q

What is the order of energy?

A

Energy input-stable system- unstable system- change- stable system

18
Q

What is the scientific method

A

It is the sequence of events that is followed to reach scientific conclusions

19
Q

What is the order of the scientific method?

A

Observation- question- hypothesis- test( Fails, remains a hypothesis. Passes then becomes a ) theory- (test- fails remains a theory, passes then it becomes a law)

20
Q

What is a hypothesis?

A

An explanation to any observation

21
Q

What is a theory?

A

A hypothesis that passed one or more tests.

22
Q

What is a law?

A

A theory that passed all tests=an undoubted answer to a question

23
Q

What is latitude?

A

It is a measurement measured by N and S

24
Q

What is longitude?

A

A measurement towards East to West
