Types of Energy
Name 4 types of energy.
Thermal, Heat, Radiant, Solar, Chemical, Electrical, Mechanical (Kinetic and Potential)
What are two types of energy that electrical energy can be transformed into?
Mechanical, sound, light, or heat.
A completely unbroken circuit that allows electrical energy to pass through is what type of circuit?
A closed circuit.
What happens to an electromagnet if the electric current stops flowing?
It loses its magnetism.
What is a conductor? What is an insulator?
Conductor - Easily allows heat to pass through.
Insulator - Does not easily allow heat to pass through.
Name three types of simple machines.
Lever, Pulley, Inclined Plane, Wedge, Screw, Wheel and Axle
The transfer of thermal energy is which type of energy?

What are the three types of heat transfer? Define them.
Conduction - Heat transfer through direct contact.
Convection - Heat transfer through currents. (Air and Water)
Radiation - Heat transfer through absorption.
Which type of simple machine is a sloping surface that reduces the amount of effort force needed to move a load?
An inclined plane
What are the two types of mechanical energy? Give an example of each.
Potential and Kinetic

A person eating an apple and then going for a run is what type of energy transformation?
Chemical (food) to Mechanical (Kinetic)
If electrical energy stop flowing to one transformer in a series circuit, will the rest of the circuit continue to work?
No, all of the other transformers would stop working as well.
What are two things that you need for get an electromagnet?
An electric current and magnetism.
