Question

what is velocity? (1 point)
velocity is a scalar quantity that tells the distance an object has traveled 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 scalar quantity that tells the acceleration 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.

Explanation:

To determine the correct definition of velocity, we analyze each option:

1. Scalar quantities have magnitude only, while velocity is a vector (has magnitude and direction). So options calling velocity scalar are incorrect.
2. Velocity is not about force or acceleration. It relates to displacement (or distance in speed - but velocity is vector with displacement) over time. The last option correctly states velocity is a vector quantity telling the distance (displacement) an object traveled over time.

Answer:

The correct option is: "Velocity is a vector quantity that tells the distance an object has traveled over a period of time." (the last option among the four choices)
