Magnetism
The area around a magnet where magnetic forces can be felt is called a/an
Magnetic Field
If mass increases, what happens to gravitational force?
It increases
Static electricity occurs due to
Friction
Electricity flows in what kind of circuit?
Closed
What is the term that describes fields affecting objects that are not in contact?
Force at a distance
What do magnetic fields affect?
Any object with magnetic properties
If distance increases, what happens to gravitational force?
It decreases
Opposite charges cause which force to occur?
Attraction/pull together
Electricity does not flow in what kind of circuit?
Open
Name one issue the Apollo missions encountered and describe how they solved it - include as much as you know about it!
Mrs. Kraft will determine if you get the points
What direction to magnetic field lines move?
What objects have a gravitational field?
Any object with mass
Electric field lines move from
Positive to negative
What is the name of the part of our circuit we used as a temporary power source? It needed to be charged.
Capacitor
Which charges move when an object becomes statically charged?
The negatives
This kind of magnet always has a magnetic field. It will act on any materials with magnetic properties. (ex. the magnetic wands we used in class)
Permanent
What type of force is caused by gravitational fields?
Attractive/pulling towards
Give three examples of experiments we did that involved static electricity
Balloon sticks to wall
Confetti and friction tool
Friction tool and water
What force can be created through an electric current?
Magnetic
If you split a permanent magnet in half, what happens to the poles?
Each half will have its own North and South
This kind of magnet does not maintain a magnetic field on its own. It must be within a magnetic field to act as a magnet. (ex. the metal leg of a chair)
Temporary
Exponentially
An object is "charged" if...
It has an unequal number of positive and negative charges
What two things impact an electromagnetic field/strength of a circuit?
The strength of the current through the wire
The coil density
