Two rocks of very different sizes are dropped from the same height. Which value will be different for the two rocks?(1 point)
the acceleration of the rocks
the velocity of the rocks after a few seconds
the downward pull of gravity on the rocks
the time it takes for the rocks to fall to the ground
A large boulder and a piece of paper are released from the same height. They take different amounts of time to fall to the ground. How can this be explained?(1 point)
The masses of the two objects are different, so they are affected differently by air resistance.
The pull of gravity is equal on the two objects, but there is more air resistance on the paper.
The masses of the two objects are the same, but they are affected differently by air resistance.
The pull of gravity is greater on the boulder than on the paper, and there is more air resistance on the paper.

2.The masses of the two objects are different, so they are affected differently by air resistance.
3.4.0 seconds
4.The objects will fall at the same time because gravity will have the same affect on them, and there is no air.
1)the surface area of the rocks
2)The surface area of the two objects are different, so they are affected differently by air resistance.
3)4.0 seconds
4)The objects will fall at the same time because gravity will have the same affect on them, and there is no air.
