lift
Lift is like a magic force that helps things go up. Imagine you have a balloon filled with air. When you let go of it, the balloon wants to fly up into the sky. That’s because the air inside the balloon is lighter than the air outside, so it gets a little push upwards. This push is a kind of lift.
Now think about an airplane. It has big wings that help it fly. When the airplane moves fast, the air goes over and under the wings. The shape of the wings makes the air move faster on top and slower underneath. This makes a special kind of lift that helps the airplane stay up in the sky, just like a bird!
Even when you jump on a trampoline, you feel a tiny bit of lift. When you push down on the trampoline, it pushes you back up. That’s lift helping you go higher. So lift is like a friendly helper that makes things rise, whether it’s a balloon, an airplane, or even you on a trampoline!
