SC.912.P.10.10: Fundamental Forces
The four fundamental forces are similar because they all describe this type of interaction.
What are interactions between matter/particles?
Static charges in an electric field are arranged based on this property.
What is charge (positive and negative)?
This type of material allows energy (electric current) to flow easily.
What is a conductor?
The strength of forces can be compared using this idea.
What is relative magnitude (strength)?
Electric field lines show the direction a positive charge would move, going from this to this.
What is positive to negative?
This material only allows partial movement of electrons.
What is a semiconductor?
The strong nuclear force is strongest because it can overcome this force in the nucleus.
What is electromagnetic repulsion between protons?
The electric force changes when this property of objects changes.
What is charge or distance?
This material prevents most energy transfer.
What is an insulator?
The magnitude of the nuclear force is best described as this compared to gravity.
What is much stronger than gravity?
The arrangement of an electric field changes when charges are this.
What is moved, added, or removed?
You would choose a conductor when you need this type of energy transfer.
What is efficient or rapid transfer of electricity/heat?
Compare the range of the four forces.
What is gravity and electromagnetic have infinite range, while strong and weak nuclear forces have very short range?
Explain why electric force changes between two objects.
What is because of changes in charge magnitude or distance between them?
Compare the impact of conductors vs insulators on energy transfer.
What is conductors allow energy to flow easily, while insulators resist or block energy transfer?
