If you do 1000j of work on a system and remove 500j of heat from it, what is the change in its internal energy

Two children stretch a jump rope between them and send wave pulses back and forth on it. The rope is 4.5 m long, its mass is 0.42 kg, and the force exerted on it by the children is 71 N.

An object will only change its motion if a force is directly applied to it. is this a true statement?
