Electric Fields
- Force Fields
- A field means a region where an object
experiences a force without being
touched.
- Magnets cause
magnetic fields and
electric charges have
electric fields around
them.
- A field means a region where an object
experiences a force without being
touched.
- Electric Fields
- In an electric field, a charged particle will
eperience a force.
- Lines of force are used to show
the strength and direction of the
force.
- The closer the field lines, the stronger the force.
- Field lines are continuous.
- In an electric field, a charged particle will
eperience a force.
- Gravitational Fields
- If a mass is lifted or dropped
though a height then work is done
(energy is changed)
- If the mass is dropped then the
energy will change to kinetic energy.
- If the mass is lifted then the
energy will change to gravitational
potential energy.
- Change in gravitational potential energy = work done.
- If a mass is lifted or dropped
though a height then work is done
(energy is changed)
- Moving charges in electric fields
- When a positively charged
particle is released from a plate
then the electrical potential
energy is converted to kinetic
energy.
- QV = 0.5 mv (squared)
- When a positively charged
particle is released from a plate
then the electrical potential
energy is converted to kinetic
energy.
- Electric field patterns
