Mass—A Measure of Inertia Standard unit of measurement for mass: the kilogram One Kilogram (kg) of any material on Earth's surface weighs 10 newtons. Away from the Earth, as on the Moon or other small bodies, 1 kg of material weighs less than 10 newtons.

Mass—A Measure of Inertia CHECK YOUR ANSWER When the string is pulled down slowly, the top string breaks. This best illustrates the A. weight of the ball. B. mass of the ball. C. volume of the ball. D. density of the ball. Explanation: The tension in the top string is the pulling tension plus the weight of the ball, both of which break the top string.

Mass—A Measure of Inertia CHECK YOUR ANSWER When the string is pulled down quickly, the bottom string breaks. This best illustrates the A. weight of the ball. B. mass of the ball. C. volume of the ball. D. density of the ball. Explanation: It is the "laziness" of the ball that keeps it at rest, resulting in the breaking of the bottom string.
