Work is a transfer of energy. Work can be done by a object outside of a system.

Work formula: W = F x d

Power is the rate in which work is performed or energy is convertet.

Power formula : P= U/t

Everyone of us is doing work on different objects every day. To work means to give energy to some object (or person) by exerting force and displacement.

An example of person doing work on object:

We can calculate work by using formula: Person is pushing the box

W=FΔX

W=work
F=force
ΔX=displacement

Comparing and Contrasting inner/outer planets:


Inner planets are Mercury, Venus, Earth and Mars. They are smaller in size then outer planets and closer to the Sun. They have less mass. The inner planets are rocky. The elements in the atmospheres of the inner planets are heavier than those in the outer planets.









Outer planets are Jupiter, Saturn, Uranus and Neptune. They are greater in size and mass than the inner planets, but they are farther away from the Sun. Their atmospheres are composed of
lighter elements than the inner planets.

1) What science ideas did you learn?
Answer:
I continued learning about the Moon and why do we have seasons.

2) How did you learn these idea?
Answer:
I learned these ideas by experiments, that we did in class.

3) Why is it important to know these ideas (what real world application is there)?
Answer:
It is important to know these ideas, because now we have more knowledges about the Moon and know what causes seasons to change.

1) What science ideas did you learn?
Answer:
I learned about Moons relationship with Sun and Earth.

2) How did you learn this idea?
Answer:
I learned this idea by worksheets.

3)Why is it important to learn this idea ( what real world application is there)?
Answer:
It is important to know because now we can understand why day and night are always changing.

1)What science ideas did you learn?
Answer:
I learned more about force and how to find an acceleration.

2) How did you learn these ideas?
Answer:
I learned these ideas by experiments in class.

3) Why is it important to know these ideas ( what real world applicitaon is there)?
Answer:
It is important, because now we know that pulling forces are always equal and we can find an acceleration if we know mass of object and force on it.

1) What science ideas did you learn?
Answer:
I learned about force on any object and continued learning how to create force diagrams.

2) How did you learn these ideas?
Answer:
I learned these ideas be experiments in class and worksheets.

3) Why is it important to know these ideas?
Answer:
It is important to know these ideas, because we can explain relationship between objects and the Earth.
