Thanks so much, makes perfect sense!

Does this mean in intro physics, when applying linear equation (V = U + at, for instance) on questions like "An object drops from a height of 45m. Find the time it takes for it to reach the ground." It's not taking air resistance into account?

Shouldn't free fall acceleration be constant at -9.8m/s^2 until the object hits the ground and turns zero?
