Acceleration is defined as the change in velocity divided by

Time elapsed

Explanation:

Acceleration is a vector quantity. It is defined as:

where

v is the final velocity

u is the initial velocity

t is the time elapsed

Acceleration is measured in meters per second squared (m/s^2). It must be noticed that acceleration is a vector, so it also has a direction. In particular:

- when acceleration is negative, it means that the object is slowing down, so acceleration is in opposite direction to the velocity

- when acceleration is positive, it means that the object is speeding up, so acceleration is in the same direction as the velocity

carla slowed down in the beginning of her trip, stopped, and then sped up

as technology advances, new experiments often expose problems in accepted theories. c
