Problem Statement

What is centripetal force?

Step-by-Step Explanation

Centripetal force is the net inward force required to keep an object moving in a circle.

  1. Identify what the question is asking. In Mechanics, 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.

Key Formula

Fc=mv2rF_c=\frac{mv^2}{r}

Final Answer

Centripetal force is the net inward force required to keep an object moving in a circle. The reliable strategy is to start from the definition, apply the correct rule carefully, and then interpret the result in plain language.
