Explain why when a ball is dropped from a height its speed increases?

The ball experiences the force of gravity which pulls it towards the centre [of mass] of the earth. According to the essence of the second of Newton's Laws of Motion, a force acting on a body accelerates it in the direction of the force. Thus, the ball speed up towards the centre of the earth.
Whenever there is a force - in this case gravity - there will be an acceleration. (To be precise, a NET FORCE is required to provide acceleration.) According to Newton's Second Law, the acceleration is equal to the force divided by the mass.

When the speed of particles in a gas increases what els increases?
As the speed of the particles in gas increases the heat of gas increases as well.
What factor will increase the speed of a sound wave in the air?
Speed of sound would increase as the temperature of the air increases Speed of sound increases as humidity of air increases Speed of sound is affected by the density of the air. As density increases velocity of sound decreases
Is it true In a rigid container when the speed of the gas molecules increases the speed of the gas also increases?
It is true that, in a rigid container, when the speed of the gas molecules increases, the temperature of the gas rises. This has nothing to do with the speed or lack of speed of the gas as a whole.
When the temperature of a medium increases the speed of sound decreases true or false?
No it is not true. When the temperature of the medium increases the speed of sound in that medium increases.
What increases as the speed of an object increases?
the kinetic energy of the object
WHEN A BALL IS DRoPPED FROM A height its speed increases why?
Acceleration due to the force of gravity.
Is the speed uniform or nonuniform of a stone dropped from a height?
The speed of a dropped stone will be non-uniform. The stone goes faster as it falls by an amount equal to 32 feet per second, per second. That means for each second of falling, the speed increases by another 32 feet per second until terminal velocity is reached.
How did Einstein explain that the mass of an object increases as speed increases?
because of momentum and kinetic energy
Why does an object dropped from a certain height have more than twice the speed of an object dropped from half the height of the previous object?
Because they undergo an acceleration. Free fall velocity is the function of a square.
Does two stones have the same acceleration if one is thrown upward from a roof and the identical one is dropped from there?
no because the higher it gets the speed increases and its do not does.
What is lighter rock or paper?
Between rock and paper, paper is lighter. However if dropped from same height they do fall at the same speed.
A stone was dropped off a cliff and hit the ground with a speed of 96 ft per second what is the height of the cliff?
240 ft
A stone is dropped from a window 5m high at what speed does it hit the ground?
Potential energy refers to the energy of an object that is released as kinetic energy when it falls back to the ground. When a stone is dropped from a height of 5m, its speed when it hits the ground is 9.9 m/s.
Rae dropped a bowling ball from a height of 8 meters. At which distance above the ground was the ball MOST likely moving at the greatest speed?
Still accelerating til it hits earth. ====================================== The height from which she dropped the ball is irrelevant. In any case, the ball was most likely moving at the greatest speed just as it hit the ground. The answer to the question is: zero.

How do you find the height of the tower given only 8 seconds stone is dropped?
distance = speed x time so the distance is just the speed of the stone x 8 seconds
What experiments can you do with acceleration?
You can drop an object from a certain height and time it to see how fast it goes. Make sure that you find the distance of the height from where you dropped it so that you can find out the speed by dividing the time by the distance.
