Instructional Segment 2: Noncontact Forces Influence Phenomena Flashcards
Electric Charge is…
A physical property of all matter that leads to electric and magnetic interactions
Most objects have a
neutral charge, no charge
Positively charged object
more positive (+) charges then negative (-) charges
Negatively charged object
more negative (-) charges than positive (+) charges
What is the law of conservation of charge?
Electric charges are never created or destroyed
What can negative charges do?
They can be transferred (discharged) between objects
Opposite charges…
attract
similar charges…
repel
What is friction?
a force that is created when 2 objects are rubbed together
What does friction do?
Increase the rate at which charges seperate
What is electric force?
The force of attraction or repulsion between objects due to their charges
Does the electric charge (+ or -) affect the strength or the electric force?
No
What are the two factors that determine the electric force of two objects??
The distance between the objects, and the magnitude of the charges
The closer the objects or stronger the magnitude…
The stronger the electric force
What is static electricity?
When there is a charge imbalance between objects
