Force
Define Force
The push and pull on an object.
What are magnets made of?
Iron
A complete circuit is also called this because energy moves around in a continuous loop.
Closed circuit.
Aristotle.
This light bulb produces more heat than light.
Incandescent.
Two teams are playing tug of war. Team A pushing with 1000 N of force. How much force must Team B need to win?
At least 1001 N of force.
A compass points north by interacting with this.
Earth's iron core.
A battery is a source of this kind of energy.
Chemical
This scientist studied gravity using a series of ramps and balls.
Galileo.
A light bulb has this many points of contact.
How does Friction affect an object in motion?
Friction acts to slow down an object in motion.
If you cut a permanent magnet into four pieces, you will have.
Four, smaller, permanent magnets.
A simple circuit would include these.
Wire, battery, lightbulb.
This scientist famous for an apple falling, created the first "laws of motion."
Netwon
This light bulb is the most energy efficient.
LED (Light Emitting Diode)
You drop a bowling ball and a marble at the same exact time. Which will reach the ground first?
All magnets have two of these.
Poles.. North/South.
What is evidence you completed your circuit?
The light bulb lights up!
An "object in motion stays in motion" is this law of motion.
Newton's First Law
This part of an incandescent bulb actually burns as energy passes through it.
The filament.
The wall pushes back, with 500 N of force.
What influence causes paper clips to attract other paper clips?
Induced (temporary) magnetism.
How are electricity and magnetism similar?
Magnets have North + and South Poles -
Electricity has positive + and negative - Electrons.
Netwon studied this force, which acts to slow an object down.
Friction
How do we calculate the speed of light?
E = mc2
Energy = mass x the speed of light squared.
