In vacuum, all masses big and small fall with the same acceleration, and reach the same speed in the same amount of time.
A writer living in the same boarding house as she, named Friedrich Bahre. They meet by bumping into each other on the sidewalk, he helping her pick up the papers of her manuscript that she dropped.
The kinetic energy of the arrow is dependent on its weight and the speed at which it is launched. if you use one bow to fire two different sized arrows, they will both have the SAME kinetic energy. a heavy arrow will shoot slower but hit harder while the light arrow will fly faster but wont impact as hard.
Yes
Yes, fall in Europe is also fall in North America. All nations in the Northern Hemisphere experiences the same seasons at the same time, as well as all nations in the Southern Hemisphere. When it is Autumn in Frankfort, Germany, it is Autumn in Frankfort, Kentucky.
It is impossible for the elephant and the robin to have the same amount of force because if they are dropped at different heights they shall fall to earth close to the same time.
In the absence of air, everything falls with the same acceleration, and reaches the same speed in the same amount of time after being dropped. If things fall through air, though, this isn't true.
yes because they have the same gravitational potential
Neither ... they would fall together.
Depends on which one is dropped first. If they are both dropped at the same time, they will both reach the ground at the same time.
In a vacuum, they will fall together. Air resistance might have a minor affect on the results.
Both will fall at the same time in vacuum because there is no resistance.
They do if the only force acting on them is gravity. If there's any difference in the way two different objects fall, it's the effect of air resistance. If it were only up to gravity alone, then all objects would fall to the ground with the same acceleration. They would have the same speed after the same amount of time, and if they're dropped together, they would hit the ground at the same exact time.
yes
If they are dropped from the same height, they will fall at equal velocities because there is no air resistance and their accelerations by gravity are equal.
Between rock and paper, paper is lighter. However if dropped from same height they do fall at the same speed.
There's no reason it should, since the water and the cup fall with the same acceleration.
