A level physics acceleration due to gravity help

1). Why does the velocity of objects increase if they’re being dropped from a greater height?

2). Does increasing air resistance decrease the velocity of a falling object? (Might sound stupid but just checking)

Thanks!

Yep that makes sense ty!

Gravity, in the simplest terms, would be the force acting on the object downwards. The force causes an acceleration downwards.

Acceleration due to gravity = 9.81 m/s^2

(1) If an object is dropped from a greater height, then that means it has a greater distance to travel through. Which means it will fall through more time, meaning it’s velocity will increase.

Why? Acceleration due to gravity means that the velocity increases by 9.81 m/s every second. The more time it falls through, the greater the velocity. So if it takes 2 seconds, then it’ll be 19.62 m/s, if it’s 3 seconds then 29.43 m/s...hope you catch my drift.

(2) Yes. It does. Gravity acts downwards, and the velocity increases in the downward direction. Air resistance acts upwards, opposing the motion. So there are accelerations in two opposite directions: one downwards due to gravity, and one upwards due to resistance.

So the velocity would decrease, because net acceleration decreases
