What is the difference between speed and velocity?

Problem Statement

What is the difference between speed and velocity?

Step-by-Step Explanation

Speed is how fast something moves, while velocity includes both speed and direction.

1. Identify what the question is asking. In Physics, this usually means naming the known quantities, the unknown quantity, and the concept that connects them.
2. Write the relevant definition, rule, or relationship before substituting numbers or manipulating symbols.
3. Work one step at a time and keep units, signs, and restrictions visible.
4. Check whether the answer makes sense in the original context.

Final Answer

Speed is how fast something moves, while velocity includes both speed and direction. The reliable strategy is to start from the definition, apply the correct rule carefully, and then interpret the result in plain language.
