Question

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)
• Air resistance causes both objects to fall at the same rate.
• Velocity causes both objects to fall at the same rate.
O Drag causes both objects to fall at the same rate.
• Earth's gravity causes both objects to fall at the same rate.

Answer 1

Earth's gravity causes both objects to fall at the same rate.

Explanation: In free fall (neglecting air resistance) all objects accelerate downward at the same rate g ≈ 9.8 m/s² regardless of mass, so the hammer and nail hit together.
