Mechanical Energy
The energy of movement.
What is kinetic energy?
It is the measure of the average kinetic energy of the particles of a substance.
What is temperature?
Hot air rises.
What is convection?
This type of circuit only has one path for electricity to flow.
What is a series circuit?
The three ferromagnetic metals on the periodic table.
What are iron, cobalt, and nickel?
What is potential energy?
The direction that thermal energy moves.
What is from hot to cold (or high to low)?
A spook left in a pot of boiling water gets hot.
What is conduction?
This type of circuit has more than one path for electricity to flow.
What is a parallel circuit?
The area of force surrounding a magnet.
What is a magnetic field?
The amount of kinetic energy in a 2,000 kg car traveling at 30 meters per second.
What is 900,000 joules?
It is the sum of the kinetic energy and the potential energy of the particles of a substance.
What is thermal energy?
A campfire roasts a marshmallow.
