Will a bullet that is shot perfectly horizontally hit the ground at the same time as a bullet dropped..?

Question

if both are dropped at the same time under the same conditions. I say yes, my friends say no. Gravity is the same for all falling object right? Where can i find info. to show them?

Answer 1

Neglecting curvature of the Earth and air resistance, yes. There is nothing holding up the shot bullet, it falls down at the same speed no matter how much sideways speed it has. That is assuming you do not aim even slightly up or down of course. I am sure you already know that, but maybe your friend doesn't.

Answer 2

i don't comprehend physics, yet i might wager that a bullet shot horizontally might commute for a 2d or 2 in the past dropping. in case you knew the gap that the horizontal bullet might commute, and dropped the different bullet from the comparable top, you may discover that they drop interior the comparable 2d. yet once you stood on an prolonged flat area, say a runway, and shot a bullet horizontally out of your shoulder top, and on the comparable 2d dropped a bullet from shoulder top, the only you dropped might hit the floor some distance swifter than the shot bullet.

Answer 3

Yes, they will. You are absolutely right.

The equation for the movement by gravity of all objects is

s=0.5gt^2

Where s is the distance traveled vertically, g is acceleration due to gravity (on earth it equals 9.8 m/s/s), and t equals time.

Your friends are confused because the bullet fired from the gun has both horizontal and vertical components to its movement, whereas the dropped one only has the vertical. The horizontal component has absolutely no effect on how fast the bullet hits the ground, only on how far it travels before it does so. The vertical component is the same for both, so they hit the ground at the same time.

Answer 4

If there is no wind, yes. If there is side wind, the spinning bullet will be influenced by Magnus effect, which will create local lift that can pull the bullet down faster, or if the wind comes from the other direction, will provide a bit of lift, decreasing its fall.
The Magnus effect has to be taken into account when sharpshooters fire at distant targets.
(Look at the attached link, under the "spin drift" section).
Of course, if your bullet is fired from a smoothbore gun, the bullet will not spin, and there will not be any Magnus effect, and the fired bullet would hit the ground at the same time as the dropped one.

Answer 5

gravity is the same for all things so bullet shot perfectly horizontally would hit the ground at the same time as a bullet droped. on a side note air ristance play a big part so metion that too your friends

Answer 6

You don’t need a PhD in physics to answer this one. Just open up the old Speer Reloading Manual and turn to page 5 or 6 (could be in a different spot but this is in any reloading manual published by bullet manufacturers, Speer, Sierra, Hornady). It explains why they will both hit at the same time.

Air currents, density, etc don’t matter. The bullet doesn’t plane like a boat; it spins and is designed to spin evenly. Possibly the only contributing factor would be a damaged tail which would cause the bullet to spin erratically which may cause their journey to the ground to be slightly different.

Answer 7

You are theoretically correct, as long as the bullet does not have aerodynamic properties such that it can fly/glide to some degree. The same is true, of course, for all forms of projectile, and was discovered and described in Newton's principles for projectile motion.

There are hundreds of sites that discuss and explain this phenomenon. I've listed on good, clear source, offered for use by 12th grade teachers.

Answer 8

You are correct if the bullet is shot in a vacuum.

Answer 9

Yes, they will both hit the ground at the same time. Show him two-dimensional kinematics. In the vertical direction, both situations are identical.

Answer 10

Yes of course. It's basic law of physics.
