Fill in the blanks: Shake something to and fro and you’re measuring its _____. Lift it against gravity and you’re measuring its _____.
The appropriate word in the blank for the statement “Shake something to and fro and you’re measuring its ____. Lift it against gravity and you’re measuring its _____.�
Answer to Problem 7RQ
Shake something to and fro and you’re measuring its mass. Lift it against gravity and you’re measuring its weight.
Explanation of Solution
When there is movement of a body in to and fro direction, then there is no movement of body against the gravity and hence the measure is only of mass. But when the movement is with respect to gravity, then there is measure of weight. This is because mass is not related with acceleration due to gravity, but weight is proportional to gravity.
Conclusion:
Shake something to and fro and you’re measuring its mass. Lift it against gravity and you’re measuring its weight.
