What is gravity?
gravity is considered one of the forces of nature, and is what gives us the sensation of weight here on Earth

Who discovered it?
Isaac Newton was one of the first on study about gravety

How does the Einstein’s Relativity Theory relate with gravity?
The theory of relativity gives a basis to show the essential unity of matter and energy, space and time, and the equivalence between the forces of gravitation.

Mention five words you might find in the video
Gravity Physics Theory Einstein Relate

2. Which of the words in the question above did you find in the video? List them Gravity Theory Einstein ==== 3. What was the embarrassing secret Newton was holding about gravity? ==== Well..He didn't know how gravity works

==== 4. The narrator presents some examples in the video. What happens in the first one? What happens to the sun and planets? Explain ==== In the first experiment the sun is destroyed and according to the theories of Newton the planets would leave their orbits and wander aimlessly in space

==== 5. What happens in the second one? What happens to the sun and planets? Explain ==== In the second experiment there gravity curves around the sun, when the sun disappears the curves begin to transform itself into waves and sea carrying the planets out of their orbits and so wander through space

6. Why was Newton’s idea of gravity incorrect for Einstein?
By the laws of Newton, the experiment shows that gravity travels faster than light, something that is not true, and Einstein provided as an argument a question: How is it possible that the planets leave of their orbits prior to receiving the darkness cause the disappearance of the sun?

7. What is the final definition of gravity given in the video?
According to Einstein, the gravity are curves working in the space-time.

8. What’s the name Einstein gave to it?
Einstein calls it like General Relativity

==== 9. What’s the difference between Newton’s gravity and Einstein’s gravity? ==== The difference between the definitions of Isaac Newton and Albert Einstein is that Newton said that gravity is a force that attracts two bodies of different masses while Einstein said that gravity is a force of attraction but when there is a object in space, the object distorts the space-time and when the space is deformed creates an acceleration which is called gravity.
