Which statement summarizes the difference between mass and weight? Mass is the downward pull on an object due to gravity, and weight is the amount of matter in an object.
Mass is the amount of matter in an object, and weight is the downward pull on an object due to gravity.
Mass is measured in newtons, and weight is measured in pounds.
Mass is measured in pounds, and weight is measured in newtons.

An experiment was performed on a 2-kg block. forces of 5, 10 and 15 newtons respectively were applied to the block for 5 seconds. describe the difference in acceleration between the three trials. a) the final accelerations will all be the same. b) the final acceleration will triple between the first and third trial. c) the final acceleration will be cut by 1/3 from the first to third trial. d) the final acceleration will increase nine time between the first and third trial.
