Exaggeration

The object compresses and elongates while keeping its volume, conveying weight and flexibility.

This is for a motion graphics video. Animate [scene] with "Squash and Stretch": the object flattens when it lands or is hit, and elongates along its direction of travel while it moves fast.
Keep its volume constant — when it gets wider it must get shorter, and the reverse — and tie every change of shape to the movement, so it reads as weight and flexibility rather than a rubber-band wobble played on the spot.
Fit the action into [duration], and deform it a lot for something soft and only slightly for something stiff.

Loosely attached parts keep moving or trail behind after the main body stops or starts, so parts do not all move and stop together.

This is for a motion graphics video. Animate [scene] with "Follow Through and Overlapping Action" (also called drag or lag): the loosely attached parts trail behind when the main body sets off, and keep going, swing past and settle after it has stopped.
The parts must not all move and stop together. They are passive — pulled along by the body — unlike a secondary action, which is a small separate gesture playing alongside the main one.
Fit the move and the settling into [duration], and let longer or lighter parts lag further and take longer to come to rest.

Outlines tremble slightly frame to frame as if redrawn each time, giving a lively handmade look even when the shape stays still.

This is for a motion graphics video. Give the outlines in [scene] a "Line Boil" (also called boiling lines or wiggly lines): redraw every line slightly differently every few frames, so it trembles in place even while the shape itself stays still.
It should change in small sudden steps at a low frame rate, like flipping through hand-traced drawings — not flow smoothly, which reads as liquid, and not shift the whole shape around, which is a wiggle.
Keep it boiling for [duration], and keep the tremble small enough that the shape stays easy to read.

The object passes its target slightly and then returns to it; differs from Bounce in that it makes one pass and settles without hitting a floor.

This is for a motion graphics video. End the move in [scene] with an "Overshoot" (also called a back ease or back out): the object runs slightly past its target, then comes back and settles on it.
It should pass the target only once, with no wobble afterwards — a bounce hits the target and rebounds without passing it, and an elastic ease swings past it several times.
Fit the move into [duration], and keep the overshoot small so it reads as energy rather than a mistake.
