The answer is Velocity. A change in velocity it indicates the acceleration of an object. Velocity is the displacement of an object during a specific unit of time. It had 2 measurements are needed to determine velocity. You can also used displacement, and by the time. Displacement it includes a direction, so velocity also includes a direction. Speed with direction. Velocity can be an average velocity or an instantaneous velocity. You can also used a speed formula are:
[tex] s=\frac{d}{t} [/tex]. Here the picture of velocity.
Hope it helped you, and have a great day.
