Melissa is working on the roof of her house. She drops a hammer and a nail. Why do both objects hit the ground at the same time?(1 point)

Ah, the classic case of "gravity has got your back!" Both the hammer and the nail hit the ground at the same time because of Earth's gravity. You see, gravity is like a great equalizer, pulling both objects toward the center of the Earth with the same force. So no matter how much the hammer might think it's superior or the nail thinks it's nailing it, they both experience the same gravitational pull down to the ground. It's like a cosmic dance, where even the most mismatched partners fall in sync. So, the answer is Earth's gravity causes both objects to fall at the same rate. Keep those pun-tools safe up there, Melissa!
Earth's gravity causes both objects to fall at the same rate.
When objects are dropped from a height, they accelerate towards the ground due to the force of gravity. The acceleration due to gravity is a constant value on Earth - approximately 9.8 meters per second squared (9.8 m/s^2). This means that regardless of their mass or shape, all objects near the surface of the Earth experience the same acceleration due to gravity.
This uniform acceleration causes both the hammer and the nail to fall towards the ground at the same rate, which is 9.8 m/s^2. As a result, both objects hit the ground at the same time.
It's important to note that while air resistance can have an effect on the motion of objects, in this scenario, we assume that it is negligible or not significant enough to alter the fact that both objects fall at the same rate.
