Work and Power Test 2025 How is work related to energy? Work is the time it takes to use energy. Work is the change in energy Mitochondria is the powerhouse of the cell Work and energy are not related.

## Step 1<br />The problem is asking us to identify the correct relationship between work and energy. The options provided are:<br />- Work is the time it takes to use energy.<br />- Work is the change in energy.<br />- Mitochondria is the powerhouse of the cell.<br />- Work and energy are not related.<br /><br />## Step 2<br />We need to understand the basic principles of physics to solve this problem. In physics, work is defined as the amount of energy transferred by a force over a distance. This means that work is a measure of the energy transferred to or from an object.<br /><br />## Step 3<br />Looking at the options, we can see that the second option, "Work is the change in energy", aligns with the definition of work in physics. This is because when work is done on an object, it results in a change in the object's energy.
