<span>The scientific investigation has five basic steps and one feedback step: (1) to make an observation (2) to ask a question (3) hypothesize (4) predict and (5) make a new hypothesis based on the results. What is unusual about the description of Elyse’s scientific investigation is she did not follow the basic steps. She should have done observation first before asking a question and forming a hypothesis. </span>

As the balls continue to accelerate to the ground, the distance between them before the first ball hits the ground will increase.
<h3>What is acceleration?</h3>
Acceleration is defined as the rate change of velocity with time.
acceleration a = (Δv) / (Δt)
Two identical heavy balls are dropped from the top of the Leaning Tower of Pisa. The second ball is dropped 1 s after the first ball. The first ball start falling 1s earlier than the second ball. Thus, the acceleration for first ball will be greater than the second ball.
Thus, the distance between them before the first ball hits the ground will increase.

Answer:
<em>Yes, they are moving in opposite direction one to the other.</em>
Explanation:
Velocity is a vector quantity, which means that it has both magnitude and direction. The magnitude shows the size of the velocity, and the direction shows which way it is moving in reference to a chosen reference direction. If the red box is assigned a positive velocity, and the blue box is assigned a negative velocity, as indicated in the question, then it means that the red box, and the blue box, both move in opposite direction to the other.
