Key Concepts
A magnetic force can convert potential energy stored in the magnetic field to ____________________.
Potential energy
To separate or set apart
Isolate
When there is only one magnet, what type of energy is there?
There is no energy, as this is not a system.
When two like poles of a magnet come together, they will ____________.
Repel
Chapter 1 Question: How can the launcher make the model ____________ move without touching it?
Spacecraft
A magnetic field is stronger ________ to the magnet.
Closer
A line that connects opposite magnetic poles and represents the strength and direction of the magnetic field.
Magnetic field line
A stronger magnet will have more _______________ and ________________ energy.
Potential and Kinetic
In order to see attraction, there has to be a __________ side of the magnet facing a __________side.
North, south (in either order)
Ch 2 Question: Where did the _____________ to launch the model spacecraft come from?
energy
Moving a magnetic against a stronger magnetic force transfers ______ energy to the magnetic field.
More
The ability to make things move or change
Energy
Better or more
Magnets will not react with ______________
Wood or non metals
Ch 3 Question: Why was there so much more ____________________ stored in the launcher system on Wednesday than on Tuesday?
Potential energy
The pattern of magnetic field lines around attracting magnets is ____________ from the pattern of magnetic field lines around repelling magnets.
Different
To move from one object to another or one place to another
Transfer
Explain the difference between kinetic energy and potential energy.
Kinetic energy is the energy when moving, potential energy is the energy that is held when the object is not moving.
Give an example of something that uses magnets.
Headphones, speakers, levitating trains, compasses, magnetic jewelry, MRI machines.
(Must get all 3)
magnetic system, force, energy
