A kg ball of lead rests next to a 10 kg rock. which statement below is true:a:the lead ball and rock have the same amount of inertia,b:if the lead ball and the rock fell from the same height in a vacuum, the rock would hit the ground first because it is less massive,c: on the moon both would have the same mass as on earth,but not the same weights as on earth,d:because the lead ball has a larger mass than the rock,it will definitely have a larger volume than the rock
There is one correct answer. Tell us what you think it is, based upon what you have learned so far.
Remember the difference between mass and weight. That should help you choose the right answer.
