Question

what is velocity? (1 point)
velocity is a scalar quantity that tells the acceleration of an object over a period of time.
velocity is a vector quantity that tells the force of an object over a period of time.
velocity is a vector quantity that tells the distance an object has traveled over a period of time.
velocity is a scalar quantity that tells the distance an object has traveled over a period of time.

Explanation:

1. Recall the definition of velocity: Velocity is a vector quantity (has magnitude and direction) that is defined as the displacement (distance with direction) of an object per unit time, or equivalently, it tells the distance (with direction) an object has traveled over a period of time.
2. Analyze each option:

• Option 1: Velocity is not about acceleration, and it's a vector, not scalar. Eliminate.
• Option 2: Velocity is not about force. Eliminate.
• Option 3: Matches the definition (vector, distance over time with direction implied in vector).
• Option 4: Velocity is a vector, not scalar. Eliminate.

Answer:

The correct option is: Velocity is a vector quantity that tells the distance an object has traveled over a period of time. (Assuming the third option in the list, but based on the text, the option "Velocity is a vector quantity that tells the distance an object has traveled over a period of time" is the correct one among the given choices.)
