If I throw something upwards will the gravity slow it down faster?

Question

So idk if this makes sense so I’m going to use numbers. If I take something, and shoot it let’s say a bullet. Into the air. The first second it will be slowing down at 9.81m/s if I’m not mistaking because gravity is pulling it down that fast. At the 2nd second. Will gravity be pulling it down at 9.81m/s still or will it go to 19.62m/s? Like will the speed be stacking essentially for how fast it slows down?

Answer 1

Let’s do some rounding and approximation so we have nicer easier numbers. We will also ignore air resistance, gravity changing with distance and all that stuff. Basically let’s ignore everything and assume a constant pull from earth’s gravitaty.

Earth accelerates objects downwards at about 10 m/s per second. The velocity decreases by 10 meter/second during each second. (that’s exactly what m/s^2 means)

So if you shoot upwards with a starting velocity of 500m/s, it will slow down to 490 m/s after one second. After 2 seconds it will have a speed of 480 m/s, after one more second it will be down to 470 m/s, the next second at 460 m/s etc.. Eventually after about 50 seconds it will reach it’s peak and stand still for a brief moment. During the next second it will start falling down with a speed of 10m/s. This speed will increase to 20m/s during the next second and so on. Until the bullet hits the ground with exactly 500m/s. That’s why it’s so incredibly dangerous to shoot straight up with a gun.
