Answer:
The answer to your question is because of the force of friction between the ball and the ground.
Explanation:
Exactly, Newton's first law states that every object persists in its state of rest or uniform motion in a straight line unless it is compelled to change that state by forces impress on it.
After analyzing Martin's experiment we could conclude that Newton's first law of motion is wrong but we must remember that between a body and the surface there is a force of friction that causes that the object comes to stop.
We can not see this force but it is there.
Answer: Both are only physical changes. •

Answer:
<h3>The answer is 7.5 g</h3>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume = 5 mL
density = 1.5 g/mL
We have
mass = 1.5 × 5
We have the final answer as
<h3>7.5 g</h3>
Hope this helps you
