Chapter 1, Problem 34A

Interpretation Introduction

Interpretation:

The measurement that depends on gravitational force needs to be determined.

Concept introduction:

Gravitational force is the effect of gravity which is one of the four fundamental forces in the universe.

Answer to Problem 34A

Weight depends on the gravitational force.

Explanation of Solution

Mass is the measure of amount of matter in a substance. Weight depends on the gravitational pull of earth on the substance. It does not only measure the amount of matter present in it.

Weight depends on the gravitational force since weight is equal to the product of mass of an object and gravity g that is:

$\text{W=mg}$

where $\text{g=9}\text{.8}{\text{m/s}}^{\text{2}}$ is constant.

Conclusion

Measurement that depends on gravitational force is weight.
