Inbetweening

In animation, inbetweening is when we draw pictures between two important pictures to make a smooth motion. It's like having a beginning and an end to a story, and we need to fill in the in-between parts to make the story make sense.

For example, let's say we have two pictures of a ball bouncing from the ground to the air. In the first picture, the ball is on the ground, and in the second picture, the ball is in the air. We need to draw pictures in between these two so it looks like the ball is moving smoothly.

Imagine you're drawing a flipbook, where you draw a picture on each page and then when you flip through them quickly, it looks like one picture is moving. Inbetweening is like adding the pages in the middle so that the ball looks like it's bouncing in a fluid way instead of just jumping from one spot to another.

Overall, inbetweening is just adding more pictures in between the important ones to make the animation look smoother and more realistic.
