What is kinetic energy?

Kinetic energy is the energy of movement. This means that when an object is moving, it has kinetic energy. For example, when a ball is rolling across the floor, it has kinetic energy.

You can imagine kinetic energy like a superhero's power. Just like a superhero has the power to do amazing things, objects that are moving have the power of kinetic energy.

Kinetic energy is measured in joules. Joules are like points on a scoreboard that tell us how much kinetic energy something has. The more joules an object has, the more kinetic energy it has.

One way to show kinetic energy is with a toy car on a ramp. As the car rolls down the ramp, it starts to pick up speed and move faster, which means it has more kinetic energy. The higher the ramp, the more kinetic energy the car will have.

Another example is a person riding a bike. As they pedal, their legs create motion, which gives the bike kinetic energy. The faster they go, the more kinetic energy the bike will have.

In summary, kinetic energy is the energy of movement. Objects that are moving have the power of kinetic energy, which is measured in joules. We can see examples of kinetic energy in toys, sports, and everyday activities.
