Energy stored because the shape changed
A (a) wave is a wave that moves perpendicular to the direction of the vibrations of that wave.
What energy transfers happen during photosynthesis according to the diagram?(Please use complete sentences)
A (a) wave is a wave that travels parallel to the direction of vibration flow in the wave.
In a food web, energy transfers from the producer to the consumer. In the diagram, where is energy flowing from and going to in this scenario? Give only one transfer. There are several correct answers. Please use complete sentences.
Choose the example with the most potential energy (PE).
A feather laying on the floor
A feather laying on the edge of a high shelf
A feather laying on the edge of a building
Four friends were at an amusement park. After they got off the roller coaster, they were discussing what was happening during the ride with the energy. This is what they said:
Ryder: “As the roller coaster climbs up the first hill, it gains potential energy. Then, as it descends, that potential energy is transformed into kinetic energy, causing the roller coaster to pick up speed.”
Sophie: “I think the roller coaster absorbs energy from the riders as it goes up the first hill. Then, all that energy is lost as the roller coaster goes down the hill and slows down."
Alaina: "Actually, I believe the roller coaster creates energy out of nowhere. It starts with a small amount of energy and then magically gains more energy as it goes through loops and twists."
Nathan: "I think the roller coaster converts all of its potential energy into kinetic energy at the top of each hill. But as it reaches the bottom, the kinetic energy is lost as heat due to friction."
Which friend do you agree with the most and Explain why you agree. Please use complete sentences.
