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 ellens kinetic energy changed? when ellen started pedaling her bike, she began moving along the street. when ellen got on her bike, her feet were no longer touching the ground.
Answer
# Brief Explanations:
Kinetic energy is energy of motion. When Ellen started pedaling and moving along the street, her state of motion changed, indicating a change in kinetic energy. Just getting on the bike and feet - not touching the ground doesn't directly show a change in motion - related energy.
# Answer:
When Ellen started pedaling her bike, she began moving along the street.
