Three students observe a toy car rolling across a level floor until it slows to a stop. After the observation, they make these statements: Max: "Energy is conserved, but friction turned it into heat, warming the floor and wheels."
Chris: "But it stops. Energy is not conserved. The car's kinetic energy disappeared.
Sam: "But energy can't just disappear. It must have become potential energy."
Which student was correct?

an electric circuit

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
