Question

A hammer and a feather are dropped from the same height by an astronaut on a planet without air. Which value will be different for the two objects?
A. The velocity of the objects
B. The time it takes for them to fall
C. The downward pull of gravity
D. The upward push of air resistance

Answer 1

Answer:

C

Explanation:

Gravity applies in the same way to all objects. A and B are not correct since all objects fall at the same velocity independent of other factors. Since there is no air, D cannot be correct.

Answer 2

The hammer and the feather will differ in air resistance.

What is air resistance?

The term air resistance has to do with the opposition offered to the movement of an object by air. This opposition offered depends on the weight of the object.

We know from the experiment of Gallileo that all objects have the same acceleration due to gravity but they do differe in air resistance hence the hammer and the feather will differ in air resistance.
