VOCABULARY
What does it mean to "repel" in terms of magnetic forces?
To push away; like poles of magnets repel each other.
True or False: A magnetic force can repel an object at a distance.
TRUE
What is a force in the context of magnetism?
A push or pull exerted by a magnetic field on an object.
What is "potential energy"?
The stored energy of an object due to its position or state.
What is a model in the context of scientific studies?
A simplified representation of a complex system used to understand or predict behavior.
Define "kinetic energy."
The energy of an object in motion
True or False: In a system of magnets, there is an attracting force between like poles.
FALSE-they repel
How do magnetic field lines indicate the strength of a magnetic field?
The closer the lines are together, the stronger the magnetic field
Describe how magnets can move objects.
By exerting a magnetic force that pulls or pushes the objects.
Describe how to annotate a model to indicate if it is a system
Use labels and arrows to show interactions and components within the system.
What is a "magnetic field"?
An area around a magnet where magnetic forces can be detected
True or False: The energy used to move a magnet against a magnetic force is stored as kinetic energy.
FALSE-potential energy
Describe what happens when two magnets with the same poles are brought close together.
They repel each other
Explain how energy is stored in a magnetic field.
Energy is stored when a magnet is moved against the magnetic field, creating potential energy
What role do magnetic field lines play in understanding magnetic systems?
They visually represent the direction and strength of magnetic forces in a system.
Explain what is meant by "convert.
To change one form of energy into another
Explain how you can tell if magnets are going to repel or attract each other in one sentence.
If the poles are the same (north-north or south-south), they will repel; if the poles are different (north-south), they will attract.
Explain the difference between potential energy and kinetic energy in magnetic fields.
Potential energy is stored energy based on position, while kinetic energy is energy of motion.
Discuss the relationship between potential energy and kinetic energy in detail.
As potential energy increases (e.g., moving a magnet against a magnetic field), it can be converted to kinetic energy when the magnet is released and allowed to move.
Explain how you would complete a model diagram for a magnetic system
Add magnetic field lines, labels for poles, and indicate forces and interactions.
Describe what a "magnetic pole" is.
The regions at the ends of a magnet where the magnetic force is strongest, typically labeled as north and south
What affects the potential energy stored in the magnetic field when moving a magnet?
The strength of the magnetic field and the distance the magnet is moved against the field
How do magnets transfer energy?
Through magnetic fields, which can exert forces on nearby objects, causing them to move and transfer energy.
Analyze the statement: "More potential energy can be stored by moving against the magnetic force of a stronger magnet." Is it true? Explain your reasoning.
True; a stronger magnetic field requires more work to move against, thus storing more potential energy.
Describe how the parts of a flywheel and ball launcher store potential and kinetic energy.
The flywheel stores kinetic energy due to its rotation, while the ball launcher stores potential energy when the ball is held back before release
