Jacob says acceleration is how fast you go. Emily says acceleration is how fast you get fast. They look to you for confirmation. Who’s correct?

Solution Step 1 of 2 Acceleration is the rate of change of velocity or it is the ratio of change in velocity to the time taken for the change. It tells about, how fast the object gains or losses its speed. That is, change in velocityv a = time taken = t Where a is the acceleration, v is the change in velocity in the given interval of time t. Acceleration is a vector, it has both magnitude and direction.
