The energy of motion best describes which of the following? a) the energy of fusion b) the energy ofan electrical charge. c) kinetic energy d) potential energy

That depends on what kind of environ meant it is in  in space it has the same force that was applied when the velocity was gained

I'm having some difficulty seeing the diagram clearly.but the question says there's a net inward force on the object.so we know right away,  from newton's 2nd law of motion, thatthat baby is accelerating.  it doesn't even matter which way thenet force is pointing.  if there's any net force, then either theobject's speed or else its direction must be changing.
