Bella had an experiment to find out which object will hit the floor first. She used 45 kg and 15 kg of blocks. Which of the following could be the result of her experiment if air resistance is NOT PRESENT or NOT CONSIDERED?
A. Both objects will hit the floor at the same time.
B. The heavier one will hit the floor first because friction is greater on objects with greater mass.
C. The heavier one will hit the floor first because gravity is greater on objects with greater mass.
D. The lighter one will hit the floor first since it’s easy for gravity to pull the object downward.

Answer:
The correct answer is C. The heavier one will hit the floor first because gravity is greater on objects with greater mass, assuming air resistance is not present or not considered.
Explanation:
This is due to the fact that the gravitational force that pulls the objects toward the ground is proportional to their mass. The greater the mass of an object, the greater the force of gravity acting on it. Therefore, the 45 kg block will experience a greater force of gravity than the 15 kg block and will hit the floor first.
