Question

which statement best describes the work and energy in these examples? example 1: running a car requires gas. example 2: humans require food to live. the gas and food are examples of energy. the gas and food are examples of work. the gas and humans are examples of work. the food and car are examples of energy.

Explanation:

Gas and food are sources of energy. Gas provides energy for a car to run (chemical energy converted to mechanical energy). Food provides energy for humans to perform biological processes (chemical energy in food is broken down and used by the body). Work is the transfer of energy through a force over a distance. A car and a human are objects that can do work, but they themselves are not work. So, gas and food are examples of energy.

Answer:

The gas and food are examples of energy.
