• Energy resources are used for transportation but not for electricity.

• Energy resources can power homes, businesses, and transportation.

• Energy resources have no impact on our daily lives.

A class is investigating friction using the setup shown below to test this hypothesis: "The smoother the landing surface, the farther the car will roll." What is ONE more piece of equipment needed to collect data to test the hypothesis AND how can the hypothesis be tested?

• A stopwatch to measure the time taken for the car to roll a certain distance.

• A ruler to measure the distance the car rolls on different surfaces.

• A scale to measure the weight of the car before and after rolling.

• A thermometer to measure the temperature of the surfaces.
