Why does improper ease-in or ease-out make motion feel abrupt?

Asked on Nov 14, 2025

Answer

Improper ease-in or ease-out can make motion feel abrupt because these easing techniques control how an object accelerates and decelerates, affecting the smoothness and natural feel of the movement. Without proper easing, the transition between motion states can appear mechanical and jarring, disrupting the flow and believability of the animation.

Example Concept: Ease-in and ease-out are animation principles that help create smooth transitions by gradually increasing or decreasing speed at the start or end of a motion. Proper application of these techniques ensures that movements mimic natural physics, providing a more organic and visually pleasing experience.

Additional Comment:

Ease-in is typically used at the beginning of a motion to start slowly and gain speed.
Ease-out is used at the end of a motion to slow down gradually before stopping.
Combining both can create a more dynamic and realistic movement.
Adjusting easing curves can fine-tune the timing and feel of the animation.
