Does a charged battery possess potential energy?
Yes, a charged battery possesses potential energy due to the stored electrical energy within it.
What is the electric potential inside a uniformly charged sphere?
The electric potential inside a uniformly charged sphere is constant and the same at all points within the sphere.
Is potential energy associated with a charged object due to its position in an electric field?
Yes, potential energy associated with a charged object is due to its position in an electric field. When the charged object is positioned in an electric field, work must be done to move the charged object to a different position, resulting in potential energy stored in the system.
What is the relationship between the electric potential of a charged rod and its distance from a point in space?
The electric potential of a charged rod decreases as the distance from a point in space increases. This relationship is described by the inverse square law, where the electric potential is inversely proportional to the square of the distance from the charged rod.
What is the relationship between the movement of charged particles and the change in their electric potential or kinetic energy?
The movement of charged particles can lead to changes in their electric potential or kinetic energy. When charged particles move in an electric field, they can experience changes in their electric potential energy. Additionally, the movement of charged particles can also result in changes in their kinetic energy, which is the energy associated with their motion.

Why is the inside of the cell membrane negatively charged at resting potential?
The inside of the cell membrane is negatively charged at resting potential because of an unequal distribution of ions, specifically more negatively charged ions inside the cell compared to outside. This creates an electrical potential difference across the membrane, known as the resting membrane potential.

How does the relationship between work and electric potential energy affect the behavior of charged particles in an electric field?
The relationship between work and electric potential energy influences the movement of charged particles in an electric field. When work is done on a charged particle, its electric potential energy changes, affecting its behavior in the electric field. Charged particles will move in a direction that minimizes their electric potential energy, following the path of least resistance. This relationship helps determine the trajectory and speed of charged particles in an electric field.
What is the relationship between the potential difference and the motion of a charged particle in a uniform electric field?
The potential difference in a uniform electric field affects the motion of a charged particle by determining the direction and speed of its movement. The greater the potential difference, the stronger the force on the charged particle, leading to faster motion in the direction of the field.
What does electrical potential mean?
Electric potential is like electric potential energy, except electric potential energy requires that you have at least two charged particles: one charged particle (can be considered to be stationary) to produce the electric field and another charged particle to be affected by that electric field. If both charged particles are positively charged, then when you move the nonstationary charged particle closer to the stationary charged particle, potential energy of the system increases, because the charged particles naturally want to repel. However, let's say you remove that nonstationary charged particle and are left with just the single charged particle. There is no more potential energy in the system, because there is no other charged particle to be acted upon by the electric field. However, the single charged particle still emits an electric field. This field is what creates "electric potential." Even though there is no second particle in the system, if you were to place a second particle into the system (let's call it a test particle), its potential energy would be equal to the electric potential multiplied by the charge of the test particle. U = kq1q2/r (electric potential energy with 2 charges, where the 0 of potential energy is infinitely far away) V = kq1/r (electric potential requiring only 1 charge) V = U/q2 (electric potential is potential energy without the second charge) U = Vq2 (electric potential energy is electric potential multiplied by second charge) There is also a concept called gravitational potential, where it's gravitational potential energy divided by the test mass. It can be a negatively charged particle. In that case, electric potential decreases as you get closer to the negatively charged particle. Even though electric potential decreases, if you have two negatively charged particles, electric potential energy increases as you move the 2nd negative charge closer to the first charge. This is because multiplying 2 negative charges makes a positive: U = k(-q1)*(-q2)/r = kq1q2/r (assuming q1 and q2 are the charge magnitudes) So in this case, it's a little weird because that's how the math works. Nature has a tendency to reduce potential energy, but potential is different and doesn't work the same way. However if the test charge was positive, the sign of electric potential energy will be the same as electric potential with respect to location. V = k(-q1)/r = -kq1/r U = k(-q1)(q2)/r = -kq1q2/r Potential energy is not the same as potential! They are related, but don't get them confused. Energy is measured in Joules. Potential is measured in Volts. Completely different units. Volts = Number of Joules / Number of Coulombs. Electric Potential = Electric Potential Energy / Charge of Test Particle
