Question 1 • Physical Science

Which statement best compares the accelerations of two objects in free fall?

Answer
A
The heavier object has a greater acceleration.
B
The object that has the smaller mass has the greater acceleration.
C
The object that has the greater surface area has the lower acceleration.
D
The objects have the same acceleration.

Explanation

Ignoring air resistance, gravity gives every freely falling object the same acceleration near Earth’s surface, regardless of mass or surface area. Therefore, the two objects have the same acceleration.
