Ablack squirrel is sitting on the ground. a red squirrel is sitting on a tree branch high above the black squirrel. both squirrels have the same mass. compared to the red squirrel, the black squirrel has kinetic energy and gravitational potential energy.

How does the kinetic energy of a charge change as the charge moves under the effect of an electric field from higher potential to lower potential? a.the kinetic energy increases.b.the kinetic energy decreases.c.the kinetic energy remains the same.d.the kinetic energy is always zero.

(**i would really appreciate if this was answered soon** ) which pair of quantities includes one quantity that increases as the other decreases during simple harmonic motion?

What is the speed of an object at a given moment?
