Imagine that two identical containers, one filled with marbles and the other filled with Styrofoam beads, are released

simultaneously from rest from the same height-say, 3 m-above Earth's surface.

(a) Which container, if either, experiences the greater gravitational force?

O the container filled with marbles

O the container filled with beads

O Both containers will experience the same gravitational force.

MY NOTES

ASK YOUR TEACHER

Justify your answer.

O Since the acceleration due to gravity is 9.8 m/s² for each container, both will experience the same gravitational

force.

O Gravitational force is directly proportional to mass, so the heavier container would experience the greater

gravitational force.

O Gravitational force is inversely proportional to mass, so the lighter container would experience the greater

gravitational force.

O Since both containers fall to the ground with the same acceleration, both will experience the same gravitational

force.

(b) Which container, if either, experiences the greater acceleration from gravity?

O the container filled with marbles

O the container filled with beads

O Both containers will experience the same acceleration from gravity.

Again, justify your answer.

O The acceleration from gravity does not depend on the mass of the falling object, so both containers will experience

the same acceleration from gravity.

Gravitational acceleration is inversely proportional to mass, so the lighter container would experience the greater

acceleration from gravity.

O Gravitational acceleration is directly proportional to mass, so the heavier container would experience the greater

acceleration from gravity.

O Since the mass of both containers is the same, they both will experience the same acceleration from gravity.
