In a diagram of electric field lines and equipotential lines, what do the blue lines represent?
Electric field lines, which indicate the direction of the force on a positive charge.
In a diagram of electric field lines and equipotential lines, what do the red lines represent?
Equipotential lines, which connect points with the same electric potential.
What is the relationship between electric field lines and equipotential lines?
Electric field lines are always perpendicular to equipotential lines.
How does the density of electric field lines relate to the strength of the electric field?
The closer the field lines, the stronger the electric field.
How does the spacing of equipotential lines relate to the strength of the electric field?
The closer the equipotential lines, the stronger the electric field.
How do you calculate the change in electric potential energy?
Use the formula: $\Delta U_E = q \Delta V$, where $\Delta U_E$ is the change in electric potential energy, $q$ is the charge, and $\Delta V$ is the electric potential difference.
What happens to kinetic energy when electric potential energy increases?
Kinetic energy decreases by the same amount, conserving total energy.
What happens to kinetic energy when electric potential energy decreases?
Kinetic energy increases by the same amount, conserving total energy.
Describe the process of an electron accelerating in an electric field.
As the electron moves from a region of low potential to high potential, it loses electric potential energy, which is converted into kinetic energy, causing it to accelerate.
Describe the process of a proton slowing down in an electric field.
As the proton moves from a region of high potential to low potential, it gains electric potential energy, which is converted from kinetic energy, causing it to decelerate.
Define electric potential difference.
The amount of energy a charged particle gains or loses when moving between two points.
Define electric potential energy.
The energy a charge possesses due to its location in an electric field.
Define conservation of energy.
The total energy of a system (electric potential energy + kinetic energy) remains constant.
Define electric field.
A region around a charged particle or object within which a force would be exerted on other charged particles or objects.
What is electric potential?
The amount of electric potential energy a unitary point charge would have at a specific location in an electric field.
