Thank you very much! :) i knew it was the right answer but i had an argument with my high school teacher(she claims to have Ph.D in physics) about that.

So is the right statement?

what if F is small? how come gravity has no affect on the change in kinetic energy?

Given some body with a constant force F acting on it upwards (The body is subject to the gravitational force due to the earth) What's the correct statement? Or: K - Kinetic Energy
