Why will a boulder and a stone falling from the same height reach the ground at the same time?

the force of gravity acting on both is the same (9.81m/s^2).
In the absence of any wind resistance two items dropped from the same height will accelerate at the same rate.
There is a video somewhere of a hammer and feather being dropped on the surface of the moon. They fall and hit the surface at the same time due to the moon having no atmosphere. Even though the gravity of the moon is approximately 1/6th of that on Earth.

If a stone and a pencil are dropped simultaneously in vacuum fron the same height which of two will reach the ground first?
They will both hit the ground at the same time.
If someone falls from a building and is pushed to the side just a few feet before ground contact would they live?
Imagine you are waiting for someone to jump from a high height, like the minimum height required for death upon impact. Imagine they get close enough to touch without falling on you, you aren't in the way. They are in arms reach, and before they reach the ground, you break the momentum with a horizontal shove, their body instead flies in a horizontal direction, and then down. Would the momentum be so broken that the velocity isn't enough to kill anymore?
Why it is dangerous to jump from significant height?
Falling from a significant height will add more momentum to the falling object and according to one of the laws of gravity, an object in motion tends to stay in motion unless acted upon by another force, so once the falling object hits the ground the momentum will try to go through the ground but the falling object will hit the ground pretty forcefully. Also why am I here I have to study for exams
If two stones one big and one small are dropped at the same time which one will reach the ground first?
depends on what is done with the long balloon, more itracate balloon animals will deflate faster than a simple balloon animal
How does acceleration affect falling objects?
As objects fall, they are accelerated by the force of gravity, which causes them to continually fall faster, until they either reach the ground, or until they reach what is known as terminal velocity, which is the speed at which air resistance is equal to the force of gravity, so that the falling object does not accelerate any more.
What occurs only when air resistance does not affect the motion of a falling object?
The mass of an object will not affect the time it takes for it to reach the ground from a fixed height. Backspace
How can height affect the time for an object to fall?
The acceleration of gravity is 32 feet per second, per second. This means that --eliminating any obvious aerodynamic considerations as there would be with, say, a feather -- the speed at which an object falls increases proportionately to the time it is falling. An object falling from a greater height will be falling for a longer time period and thus will reach a higher velocity and impact the ground with a greater force than one falling from a lower height.
If water was spilled from aeroplane height would it reach the ground?
Yes.
When was Falling Out of Reach created?
Falling Out of Reach was created in 2007.
What is the height of a ten year old?
As long as your legs can reach the ground, you'll be all right...

When do you harvest pecans?
When they fall to the ground, then pick them up. If some appear to be loose, but aren't falling, then use a pole to reach them to knock them down.
How long would a penny be falling if dropped off the Burj Khalifa?
In a vacuum (i.e. neglecting air resistance) a falling object would reach a speed of about 124.2 m/s (278 mph) in falling 828 m. However, in an average configuration, a coin would reach terminal velocity at about 18.7 m/s (42 mph) and take approximately 45 seconds to reach the ground from 828 m. Edge on, it could reach 29 m/sec (65 mph) and be on the ground in just 31 seconds. Note that you cannot drop a coin straight down, but would have to throw it outward a distance of at least 15 m (50 feet) to reach the ground. *Base jumpers who jumped from the top of the building (2717 feet) took about 80 seconds to reach the ground including 10 seconds of freefall.
Sample projectile motion and falling objects word problems?
a stone is thrown from the top of a building with an initial horizontal velocity of 20 m/s if it is thrown from a height of 30 m and air resistance is neglected, find: a) time it takes the stone to reach the ground b) range
