452 15. Motion

Smooth
Smooth motion speed means that your layer is going to accelerate at the
beginning of the motion, reach a top speed, and begin to decelerate once it
comes to its stopping point. This is the default value and generally makes
motion feel the more natural.

Accelerate
Accelerate means that your layer will constantly speed up while moving. It
will start moving slowly and begin moving faster until it comes to an abrupt
stop at the end.

Decelerate

Decelerate is exactly the opposite of the Accelerate motion style. In this
case, your layer will start by moving very fast and gradually slow down until
it stops at the ending point.

Motion Speed is considered an advanced feature and may not be
something you work with on a regular basis. It does have uses in the right
effects, though.
As an example, let’s say you’re going to pan a picture of a car across the
slide. Rather than use the default Smooth motion (which will start slowly,
speed up, then slow down), try changing the motion style to Accelerate. As
the car pans across the screen it will move faster and faster as the slide
plays.
