MASS and WEIGHT Commonly misunderstood quantities

A MASS WEIGHT Definition constant variable Measured with balance Scale Measurement of the amount of matter in an object Measurement of the gravitational force Variable/constant constant variable Measured with balance Scale Units Grams, kilograms, etc. Pounds, ounces, etc. A

WEIGHT

The earth’s size makes all other attractions inconsequential

STRENGTH OF GRAVITY DEPENDS ON SIZE AND DISTANCE

Further you are away from earth …

A MASS WEIGHT Definition constant variable Measured with balance Scale Measurement of the amount of matter in an object Measurement of the gravitational force Variable/constant constant variable Measured with balance Scale Units Grams, kilograms, etc. Pounds, ounces, etc. A

Would you weigh the same on the moon?

195 million 21 trillion
