Multiple choice

Which of the following is more elastic?

  1. Rubber

  2. Glass

  3. Steel

  4. Brass
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In physics, elasticity refers to a material's ability to return to its original shape after being deformed. Steel is more elastic than rubber because it requires a greater force to produce a given deformation and returns to its original state more perfectly.

Multiple choice
