Question

which statement most completely describes an objects motion?
o the rain falls at a rate of one inch per hour.
o a marble rolls 10 m to the left.
o a car travels 25 miles.
o the baby crawls 10 feet in 15 seconds toward the door.

Explanation:

To describe an object's motion completely, we need to know the distance (or displacement), time, and direction.

• "The rain falls at a rate of one inch per hour" only gives a rate (no specific direction for a particular object's motion).
• "A marble rolls 10 m to the left" has distance and direction but no time information.
• "A car travels 25 miles" has distance but no direction and time.
• "The baby crawls 10 feet in 15 seconds toward the door" has distance (10 feet), time (15 seconds), and direction (toward the door).

Answer:

The baby crawls 10 feet in 15 seconds toward the door.
