Task 3. Read the text «Is Gravity a Theory or a Law?» and decide if the statements are true, false or not mentioned in the text.

1. The scientific law gives a formula that tells us what things will do and why it happens.

2. Both scientific laws and scientific theories are produced from the scientific method through the formation and testing of hypotheses.

3. Scientific theories give explanations of why and how things happen.

4. Newton's Law of Universal Gravitation tells us that the gravitational attraction force is directly and inversely proportional to the square of the distance between the point masses.

5. Newton's Law of Universal Gravitation states that every point mass in the universe attracts every other point mass with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

1) Little Johnny in a science class, learning about «Gravity»...

Teacher: When you throw something up.. Where will it go next?

Someone shouted: Down!

Johnny: Nooo.. It goes side first.

Teacher: Why?

Johnny: It should be Up-Side-Down!

2) Question: What is the center of gravity?
Answer: The letter V!

3) Physics Teacher: «Isaac Newton was sitting under a tree when an apple fell on his head and he discovered gravity. Isn't that wonderful?»

Student: «Yes sir, if he had been sitting in class looking at books like us, he wouldn't have discovered anything».

«Music is the arithmetic of sounds as optics is the geometry of light».
