Energize Everything

A girl was sitting on a swing. Her brother pulled the swing back and let go. When the swing comes back, will it hit him? (He stands still and doesn't move at all.)

• Yes, because the swing gets more energy when it's moving.

• Yes, because the swing will be going fast by the time it gets to him.

• No, because the swing is only going fast when it's away from him.

• No, because the swing won't have enough energy to go higher than where it started.

Which answer is correct?

• Coaster A will go faster because it's taller and has more gravitational energy stored in the first hill.

• Coaster A will go slower because it has more hills to climb up.

• Coaster B will go faster because it has less hills.

• Coaster B will go faster because it has a smaller hill in the beginning and less gravitational energy is stored.

Which of the answers are correct?

• The long wire of the LED bulb should be connected to the + side of the battery.

• The short wire of the LED bulb should be connected to the + side of the battery.

• It doesn't matter which wire is connected to which side.

Why are wires made of copper or aluminum?

• They are shiny and reflect light.

• They burn easily.

• They are good conductors of energy.

• They are cheap materials to buy.

Which type of energy should Ashville use and why?

• Solar energy because they get about 300 sunny days each year.

• Wind energy because they have winds at 5 miles per hour.

• Water energy because they have a stream.

• None of these alternative types of energy would work in Ashville.

Will the lamp be able to spin the fan really really fast from this position?

• Yes, it will heat up the top and spin it.

• No, the lamp isn't hot enough.

• Yes, the lamp will heat the cup and cause it to spin.

• No, because heat rises, so the lamp should be beneath the cup.
