Explanation:

To classify objects as "At Rest" or "In Motion", we determine if their position relative to a reference point is changing. An object at rest has no change in position, while an object in motion has a changing position.

At Rest:

• A bicycle leaning against the garage: Not moving relative to the garage.
• A slide at the playground: Stationary structure.
• A golf ball sitting on a tee: Not moving from the tee.
• A book on the shelf: Stationary on the shelf.

In Motion:

• A hockey puck sliding across the ice: Moving across the ice.
• A car being driven down the street: Moving along the street.
• A baseball thrown by a pitcher: Moving through the air.
• A surfer riding a wave: Moving with the wave.
