Questions & Step-by-Step Solutions

What is the formula for kinetic energy? (2023)
  • Step 1: Understand that kinetic energy is the energy an object has due to its motion.
  • Step 2: Identify the variables in the formula: 'm' represents the mass of the object, and 'v' represents its velocity.
  • Step 3: The formula for kinetic energy is written as KE = 1/2 mv².
  • Step 4: In the formula, '1/2' means you take half of the product of mass and the square of velocity.
  • Step 5: To calculate kinetic energy, you need to know the mass of the object and how fast it is moving.
