Identify the type of energy stored in the compressed spring. State the type of useful energy in the toy car which increases as the spring unwinds. State one type of wasted energy which increases as the spring unwinds.
Understand the Problem
The question is asking about the types of energy involved in the operation of a wind-up toy car, specifically the energy stored in a compressed spring, the useful energy produced as the spring unwinds, and a type of wasted energy that increases as the spring unwinds.
Answer
Elastic potential energy, kinetic energy, thermal energy.
The type of energy stored in the compressed spring is elastic potential energy. The useful energy in the toy car as the spring unwinds is kinetic energy. The wasted energy that increases as the spring unwinds is thermal energy due to friction.
Answer for screen readers
The type of energy stored in the compressed spring is elastic potential energy. The useful energy in the toy car as the spring unwinds is kinetic energy. The wasted energy that increases as the spring unwinds is thermal energy due to friction.
More Information
Elastic potential energy is stored when the spring is compressed. As it unwinds, this energy is converted to kinetic energy, moving the car. Some energy is lost as thermal energy due to friction.
Tips
Confusing potential and kinetic energy types can lead to errors. Remember, potential energy is stored energy, while kinetic is energy of motion.
