Momentarily at Rest

Definition

When an object is momentarily at rest, it means its velocity is zero for a brief period of time before it starts moving again. In other words, its speed becomes temporarily zero without necessarily changing direction.

Related terms

Zero Velocity: When an object has zero velocity, it means it's not moving and staying still.

Turning Points: Points on a graph where the slope (or derivative) changes from positive to negative or vice versa. At these points, objects may be momentarily at rest if their velocities change direction.

Critical Points:

Points on a graph where either the first derivative or second derivative (or both) equal zero. These points can indicate when objects are momentarily at rest or experiencing extreme changes in velocity.
