Forces & Motion
This force is always perpendicular to the surface an object is on
Normal force
It is a device that turns chemical energy to electrical energy
Battery
A disturbance that transfers energy through space and matter
Wave
A material that prevents heat transfer
Insulator
This physicist developed the theory of relativity; best known for the equation E=mc2
Albert Einstein
Newton's ____ Law states that every action has an equal and opposite reaction.
Third
It is the "push" that makes charges move
Voltage
Light wave are what type of wave?
Transverse
The average kinetic energy in the particles of an object
Temperature
First woman to win the Nobel Prize after she discovered radioactivity
Marie Curie
Static, sliding, rolling, kinetic; these are all types of ____.
Friction
If an electrical circuit has a 5 V battery and a a 25 Ω resistor, how much current is there in the circuit?
0.2 A / 0.2 Amperes
V = IR (Ohm's Law)
I = V/R = 5 V / 25 Ω = 0.2 A
