Acceleration

Key Questions

• How is the acceleration of a moving object determined?

  Answer:

  #a=(v-u)/t#

  Explanation:

  From the formula, acceleration of a moving object is determined by identifying two states of that moving object. This is the initial velocity and time, and the final velocity and time. Once you identify the two states, plug them into the formula then you will get the answer.
