 * Good job... 6pts **
 * Video 2: The Elegant Universe Einstein's - Relativity**


 * Before watching**
 * What is gravity?**

The gravity is the acceleration that an object experiment when it approaches a planet or satellite. When we consider the mass of the object, we can call the interaction of this mass and gravity, gravitational force.


 * Who discovered it?**

It was discovered by Isaacs Newton.


 * How does the Einstein’s Relativity Theory relate with gravity?**

The relationship between theory of relativity and gravity is that according with this theory, the gravity warps space and time.


 * Mention five words you might find in the video**

Gravity. Universe. Force. Acceleration. Planets.

 * During watching and after watching**
 * 1. Click on the following link to watch the video:**

Gravity. Universe. Force. Acceleration. Planets.

3. **What was the embarrassing secret Newton was holding about gravity?**

he embarrassing secret was,he had not know how the gravity actually work.

4. **The narrator presents some examples in the video. What happens in the first one? What happens to the sun and planets? Explain**

the narrator exhibits an experiment where occur cosmic catastrophe, the Sun completely disappears. When this happens the planets travel in a straight line, because there is not a force of attraction that keeps them in orbit.

5. **What happens in the second one? What happens to the sun and planets? Explain**

The narrator presents the same example, but now, according Einstain, if the sun disappears, it will create a wave to travel through space-time and the changes that occur will be observed when the wave reaches Earth.

6. **Why was Newton’s idea of gravity incorrect for Einstein?**

__The idea Newton__ ** ?? **of gravity was incorrect for Einstain because Newton does not consider a rapidity in which the gravity travels.


 * 7. What is the final definition of gravity given in the video?**

__einstainse__ ** ?? **said that space was linked with time and by the geometry of the universe conclude that objects move on this combination of the space-time and this combination is called gravity

8. **What’s the name Einstein gave to it?**

The name that Einstein gives to it was General Relativity


 * 9. What’s the difference between Newton’s gravity and Einstein’s gravity?**

The difference between Newton's gravity and Einstein’s gravity, is that Newton did not take into account the speed of light.
