--Was air resistance noticeable?
Yes, air resistance is noticeable because according to the graphs, as the object ascended into the air, its velocity decreased; likewise, the acceleration decreased. This shows that air resistance is noticeable because if there was no air resistance, the object would've kept a constant speed throughout its flight.
--Was energy conserved?
No, energy was not conserved because according to the graphs, as the gravitational potential energy decreased, the kinetic energy increased. Gravitational potential energy increases as the object ascends, and kinetic energy decreases. Gravitational potential energy decreases as the object descends, while kinetic energy increases.
--Was momentum conserved?
No, momentum was not conserved because there WAS air resistance present to affect its momentum in the air. If there was NO air resistance, the would be nothing to affect its momentum, so momentum would have been conserved.
