100
This is a complete path through which electricity can flow.
What is a circuit
100
This is a simple machine that is flat a flat and sloped surface.
What is an inclined plane
100
This is the force that causes an object to move in a circle.
What is centripetal force
100
This is a type of magnet that lasts for a very brief period of time.
What is a temporary magnet.
100
This is a form of energy resulting from charged particles.
What is electricity
200
These are equal forces acting on a object.
What are balanced forces
200
This simple machine is a rigid bar that pivots on a fulcrum.
What is a lever
200
This is the force that pulls two objects with mass together.
What is gravity
200
This is a type of magnet that is created by electric current and can be switched on or off.
What is an electromagnet
200
This is the electricity resulting from the build-up of charged particles.
What is static electricity
300
These are unequal forces acting on an object.
What are unbalanced forces
300
This is the state in which an object's distance from a reference point is changing.
What is motion
300
BONUS: What law that states that the current through a conductor between two points is directly proportional to the voltage of the two points.
Ohm's Law
300
This is the difference in electrical potential energy between two points in a circuit.
What is voltage
300
This is a coil of wire that acts as a bar magnet.
What is a solenoid
400
This is an object's resistance to movement; it relates to mass.
What is inertia
400
This is the force that is exerted on a object when they rub together.
What is friction
400
The attractive or repulsive force resulting from the movement of electric charges.
What is magnetism
400
These are the ends of a magnet where the magnetic forces are strongest.
What are the magnetic poles
400
This is a device that converts electrical energy to mechanical energy.
What is an electric motor
500
This is the product of an object's mass and velocity.
What is momentum.
500
This is the sum of the forces acting on an object.
What is net force
500
This is a type of magnet that lasts an incredibly long time.
What is a permanent magnet
500
This device uses a free-spinning needle that aligns itself with the Earth's magnetic field to determine direction.
What is a compass
500
BONUS: What is the First Law of Thermodynamics?
Law of Conservation of Energy (Energy is never created or destroyed)
