Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the core tenet?Local indistinguishability between gravitational effects and inertial acceleration
2. What is the theoretical framework?Foundation of Albert Einstein's Theory of General Relativity
3. Why did Einstein use the Equivalence Principle?It helped him see gravity as curved space, which led to his Theory of General Relativity.
4. What is the Weak Equivalence Principle?It says all objects fall at the same speed in a gravity field, no matter what they are made of.

Geodesic: The shortest path between two points on a curved surface or in spacetime.
Metric Theory of Gravity: A class of theories where gravity is described by a spacetime metric tensor.
Gravitational Lensing: The bending of light by gravity, causing distant objects to appear distorted or magnified.
