Consider the image above. vi = the initial velocity and vf = the final velocity. is there acceleration? explain your answer.
a) no. the initial and final velocities are the same.
b) yes. the ball had to slow down in order to change direction.
c) no. acceleration is the change in velocity. the ball's velocity is constant.
d) yes. even though the initial and final velocities are the same, there is a change in direction for the ball.

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
