Question

This table shows four examples of experiments.

A 2-column table with 4 rows. The first column labeled person has entries Lily, Astrid, Henry, Bob. The second column labeled Experiment has entries Measure the energy change in a compress spring, Measure the energy change when rolling a ball down a hill, Measure the work being done when a dart is thrown, Measure the work being done when a box is lifted to a shelf.
Which describes who will record their measurements in joules?

Lily and Henry
Astrid and Bob
Lily, Astrid, Henry, and Bob
Astrid, Henry, and Bob

Answer 1

Lily, Astrid, Henry, and Bob.

Both work and energy are measured in joules (1 J = 1 N·m), so all four experiments record measurements in joules.
