Based on what you learned about the bike ride, which of the following statements about energy transformations are true? Select all that apply.
There are many types of energy. One type is kinetic energy, which is the energy an object has when it is moving.
Read the passage about a bike ride. Think about the kinetic energy of the person riding the bike.
Ellen was training for a bike race. One afternoon, she grabbed her helmet and took her bike out to the street. She got on the bike and started to pedal, pushing hard to start moving forward.
Which of the following is better evidence that Ellen's kinetic energy changed?
Read the passage about the next part of the ride. Think about the evidence for changes in kinetic energy and sound energy.
By the time Ellen reached the top of the hill, she was exhausted and breathing hard. So, she stopped pedaling and coasted toward a water fountain. As she coasted, she heard gravel crunch beneath her tires, and her bike slowed to a stop.
Consider the following claim:
While Ellen's bike was on the gravel, kinetic energy was converted to sound energy.
Which piece of evidence best supports the claim?
