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
When the temperature of a medium increases the speed of sound decreases true or false?
False. In general, the speed of sound increases as the temperature of a medium increases. This is because higher temperatures lead to greater molecular motion, which increases the speed at which sound waves can travel through the medium.
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.
As the temperature of a medium increases the rate of speed of sound through the medium what?
The speed of sound through the medium also increases.
WHEN A BALL IS DRoPPED FROM A height its speed increases why?
Acceleration due to the force of gravity.
When a ball is dropped from a height its speed increases gradully?
When a ball is dropped from a height, it accelerates due to the force of gravity acting on it. As it falls, its speed increases at a steady rate until it reaches terminal velocity, at which point the speed remains constant due to air resistance balancing the force of gravity.
When a ball is dropped what type of energy increases?
When a ball is dropped, its potential energy decreases due to the decrease in height, while its kinetic energy increases as it gains speed due to gravity pulling it downwards.
A ball is dropped from a certain height. What is its initial speed?
When a ball is dropped from a certain height, its initial speed is 0 m/s as it starts from rest. The ball gains speed as it falls due to gravity pulling it downwards.
How did Einstein explain that the mass of an object increases as speed increases?
because of momentum and kinetic energy
A softball is dropped off of the side of a building As the ball continues to fall freely the kinetic energy of the ball?
increases while potential energy decreases. This is because the ball is losing height and gaining speed as it falls due to the force of gravity acting upon it.
Is the speed uniform or nonuniform of a stone dropped from a height?
The speed of a stone dropped from a height is nonuniform because as it falls, its speed continuously changes due to the gravitational force acting on it. The stone accelerates as it falls towards the ground, increasing its speed until it reaches terminal velocity when the forces of gravity and air resistance are balanced.
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.
When 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.
Is there any relationship between speed and height?
Yes, there is a relationship between speed and height. When an object falls from a greater height, it gains more speed due to acceleration from gravity. This means that the higher an object is dropped from, the faster it will be moving when it hits the ground.
Do two objects of the same mass dropped at different height have a different speed?
Yes, two objects of the same mass dropped at different heights will have different speeds when they hit the ground due to the influence of gravity. The object dropped from a higher height will have a higher speed upon impact because it had more time to accelerate while falling.
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.
