# Net work done by projectiles?

When the projectile is in motion what is the net work done on projectiles?

What i think? 0

first view: We know when we throw projectiles the initial KE and final KE is 0. So from work energy theoram the net work done must be 0.

second view: Lets see from the perpective from x direction and y direction. In X direction velocity is constant meaning there is no acceleration which in turn means force is 0 and in Y direction there is no displacement and $Work done = F \times displacement$ so it is zero in Y direction as well. So overrall net work done is zero.

I am currently reading GCSE mechanics and all the mathematical modelling is true such as neglecting air resistance . So lets see it from classical physics view only.
