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. How heavy is Mass?Mass increases with velocity according to special relativity
2. What is the equivalence principle?Inertial mass and gravitational mass are fundamentally equivalent
3. What is the higgs mechanism?Elementary particles acquire mass through interaction with the Higgs field
4. Why does mass matter in physics?Mass tells us how hard it is to change an object's speed (its inertia) and how strong its gravity is.
5. How did Einstein change our idea of mass?He showed that mass can grow when something moves fast and that mass and energy are the same thing (E=mc²).

Inertial Mass: A measure of an object's resistance to acceleration when a force is applied.
Gravitational Mass: A measure of the strength of an object's gravitational field and its response to gravity.
Equivalence Principle: The principle stating that inertial mass and gravitational mass are equivalent.
Spacetime Curvature: The warping of space and time caused by the presence of mass and energy.
