Question

17/26
what is acceleration?
the measure of mass
the measure of distance traveled
the measure of force
the measure of the change of velocity over time

Explanation:

Acceleration is a fundamental concept in physics. By definition, it is calculated as the change in velocity divided by the time taken for that change. Mathematically, \(a=\frac{\Delta v}{\Delta t}\), where \(a\) is acceleration, \(\Delta v\) is the change in velocity, and \(\Delta t\) is the time interval. Among the given options, the description "The measure of the change of velocity over time" aligns with this definition. The other options: "The measure of mass" refers to an object's inertia (a property related to matter quantity), "The measure of distance traveled" is simply displacement or length covered (a kinematic quantity different from acceleration), and "The measure of force" (from \(F = ma\), Newton's second law) is a different physical quantity that causes acceleration but is not acceleration itself.

Answer:

The measure of the change of velocity over time.
