Electric Potential

What is the change in electric potential energy ($\Delta U_E$) when a +2 C charge moves through an electric potential difference ($\Delta V$) of +5 V?

A positive charge is placed in a uniform electric field. In which direction will the charge move?

A -1 C charge moves from a point with a potential of 10 V to a point with a potential of 20 V. What is the change in electric potential energy?

A force moves a +3 C charge from point A to point B in an electric field. The electric potential at A is 5 V, and at B is 15 V. If the force does 60 J of work, what is the change in electric potential energy?

A charged particle moves through a potential difference while also experiencing a frictional force. How does this affect the conservation of energy?

A proton is placed in a non-uniform electric field. The electric field is stronger closer to point P. How does the force on the proton change as it moves closer to point P?

What principle states that the total energy in an isolated system remains constant?

An electron moves through a potential difference of 50 V. If its initial kinetic energy was 100 J, what is its final kinetic energy, assuming no other forces act on it?

A proton with an initial speed of $v_i$ moves through a potential difference of $\Delta V$. Which of the following equations can be used to find its final speed $v_f$?

A negative charge moves from point A to point B. The electric potential at A is lower than at B. Does the electric field do positive or negative work on the charge?
