Kinetic, elastic, and gravitational energy explained

Principles of energy • Energy stores and changes

Key concepts

What you'll likely be quizzed about

  • Kinetic energy is the energy of a moving object.
  • It depends on the mass of the object and the square of its velocity.
  • The formula for calculating kinetic energy (KE) is KE = 1/2 mv², where m represents mass and v represents velocity.
  • This energy form increases as either the mass or the speed of the object increases.
  • In practical applications, objects in motion like cars, bicycles, and running athletes showcase kinetic energy in action, where faster movement translates to greater energy.
