Step-by-step solution

Problem Statement

What is kinetic and potential energy?

Step-by-Step Explanation

Kinetic energy is energy of motion, while potential energy is stored energy due to position.

  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

K=12mv2K=\frac{1}{2}mv^2

Final Answer

Kinetic energy is energy of motion, while potential energy is stored energy due to position. The reliable strategy is to start from the definition, apply the correct rule carefully, and then interpret the result in plain language.
