Gravitational Fields
A property of gravitational fields where gravity can act as only an attractive force.
What is a monopole?
The charge carrying particles that cause the flow of electricity.
What is an electron?
A property of magnetic fields where a magnet must always have a North and a South pole, meaning they can attract and repel.
What is a dipole?
The name of a type of satellite that maintains orbit above the same location on Earth?
What is a geostationary satellite?
The type (attractive, repulsive) of force two electrons will experience when placed close to each other.
What is a repulsive force?
The method used to find the induced magnetic field around a current-carrying wire.
What is the right-hand grip rule?
The law where gravitation field strength drops off significantly as distance between objects increases.
What is the inverse square law?
Constant fields, which do not change in intensity or direction over time
What is a static field?
The unit for magnetic field strength.
What is a Telsa?
The name of the constant 'G' that is used in gravitation field questions.
What is the universal gravitational constant?
What is a conductor?
There are four rules to drawing fields:
1. The arrow shows the direction of the field
2. The further the field lines are apart, the weaker the field.
3. Field lines start and end perpendicular to the surface.
What is the fourth rule?
What is the field lines should never cross?
