What is Increase in kinetic energy?

Kinetic energy is the energy of movement, and an increase in kinetic energy means something is moving faster or harder than before.

Imagine you're on a swing. When you're just gently swaying back and forth, you have some kinetic energy. But when you pump your legs and go higher, you’re moving faster, that’s when your kinetic energy increases!

Think of a friend riding a bike. At first, they’re going slowly, but then they pedal harder and zoom past you. They’ve got more speed, which means their kinetic energy has increased.

It's like when you push a toy car, the harder you push, the faster it goes, and the more energy it has while moving.

If you know how fast something is going, you can find out its kinetic energy. The formula looks like this:

Kinetic Energy = ½ × mass × speed²

But don’t worry, you don’t need to remember that right now. Just think about things moving faster or harder, that’s when their kinetic energy increases!
