In the rubber band car experiment, the stretched band stores elastic potential energy. When released, what form of energy does it transform into that makes the car move forward?
Kinetic energy, transformed from elastic potential energy.
What is the law of conservation of energy
Energy cannot be created or destroyed.
What month of the year has 28 days?

KE = 0.5 * mv²
Two rubber band cars are tested: Car A is wound 3 times, and Car B is wound 10 times. Which car has more potential energy stored, and how does this affect the distance travelled?
Car B, because more winding increases elastic potential energy, which converts to greater kinetic energy and allows the car to travel further.
Most of our energy on Earth originates from ...
the sun
