Energy and motion go hand in hand. Energy is often needed to make things move. Let's break it down into simple points:

• What is Energy?
  Energy is the ability to do work. It comes in different types. Two important kinds are:

  • Kinetic energy: This is the energy of things that are moving.
  • Potential energy: This is stored energy, like energy in an object that isn’t moving yet.

• Kinetic Energy:
  When something is moving, like a ball rolling on the ground, it has kinetic energy. We can figure out how much kinetic energy it has using a simple formula:

  • Kinetic Energy = 1/2 × mass × (speed × speed) Here, "mass" is how heavy the object is, and "speed" is how fast it's going.

• Potential Energy:
  A still object, like a book sitting on a shelf, has potential energy. If the book falls, that stored energy changes into kinetic energy, which is energy in motion.

In short, energy is really important for everything that moves. Understanding how energy and motion connect helps us learn more about how our world works!
