Scientific laws

Definition

Scientific laws are statements based on repeated experimental observations that describe some aspect of the universe. They predict the results of certain initial conditions and are universally accepted within the scientific community.

5 Must Know Facts For Your Next Test

1. Scientific laws are often expressed in mathematical formulas.
2. Unlike theories, scientific laws do not explain why phenomena occur but rather describe how they happen.
3. Examples include Newton's Laws of Motion and the Law of Gravity.
4. Scientific laws are derived from empirical data through rigorous experimentation and observation.
5. They remain valid until new evidence disproves them, although this rarely happens due to their strong empirical basis.
