Is the height of a ball's bounce affected by the height from which the ball is dropped dependent and independent variable?
The height from which the ball is dropped is the independent variable, as it is what is being manipulated. The height of the ball's bounce is the dependent variable, as it is what is being measured and is affected by the height from which the ball is dropped.
A dropped ball doesn't bounce back to its starting height how does this situation fit the law of conversation of energy?
When a ball doesn't bounce back to its starting height after being dropped, it signifies that some of the potential energy that was present when the ball was held up (before being dropped) has been converted into other forms of energy, such as heat and sound upon hitting the ground. The total energy in the system remains the same, adhering to the law of conservation of energy.
What happens to kinectic energy when height increases?
As height increases, potential energy increases while kinetic energy decreases. This is because some of the kinetic energy is being converted into potential energy due to the increase in gravitational potential energy at higher heights.
What is in example of energy being lost?
When a ball is dropped from a height, some of its potential energy is lost as it moves through the air due to air resistance and friction. This results in the ball reaching a lower kinetic energy at the bottom of its fall compared to the initial potential energy it had at the top.
What best describes the greatest height a ball with bounce off the ground after being dropped from a height of 50 cm?
The ball will bounce back to a height less than its original drop height of 50 cm due to energy loss during each bounce. The exact height the ball will bounce to depends on the ball's elasticity and the surface it bounces on.

What happens to gravitational energy in relationship to height?
Gravitational potential energy is proportional to height. This can be seen in the formula:GPE = mgh (mass x gravity x height) It should be clear that,other things being equal, this means that twice the height implies twice the energy.
What happens to kinectic energy when height increases?
As height increases, potential energy increases while kinetic energy decreases. This is because some of the kinetic energy is being converted into potential energy due to the increase in gravitational potential energy at higher heights.

How many times will a ball bounce?
It depends what height you drop the ball and what surface the ball is being dropped on.
Why doesn't a pendulum go higher to where it was initially dropped?
In a pendulum, as energy is constantly being converted from potential energy (at the highest point) to kinetic energy (at the lowest point) and back again, some energy is lost to factors such as air resistance and friction. This loss of energy prevents the pendulum from swinging back to its initial height.
What is an example of dropping an object with greater height that the impact would be bigger?
Momentum and kinetic energy, but this is true only up to a point. Objects dropped in Earth's atmosphere will reach a "terminal velocity" when the force of gravity equals the force of friction or air resistance. The height at which this happens will depend on its mass, density, and shape.
What type of energy is involved when a ball is dropped?
When a ball is dropped, the energy involved is primarily gravitational potential energy being converted into kinetic energy as the ball accelerates towards the ground. When the ball hits the ground, some of this kinetic energy is transferred to the ground as impact energy.
How does the drop height of a ball affect the height of its bounce?
The higher the height at which the ball is dropped from, the higher the ball bounces. Look at it in terms of energy. Initially, before the ball is dropped, the ball's potential energy, E is given by E = mgh, where m is the mass of the ball, g is the gravitational acceleration and h is the height of the ball. When the ball is dropped, the potential energy is converted to kinetic energy, and at the point of impact, , i.e. when the ball is level with the ground, and h = 0, the kinetic energy is E, given by E = 0.5mv2, where v is the velocity of the ball. The ball hits the ground, and rises again - its kinetic energy is being converted back to potential energy. The ground absorbs some of the energy upon impact, but most of the energy stays with the ball. So the kinetic energy is converted to potential energy, and once all of the kinetic energy is converted, the ball reaches its maximum height. Clearly, a higher kinetic energy corresponds to a higher bounce height. 0.5mv2 = mgh The amount of energy that the ground absorbs does not change much with the height of the ball as well.As the drop-height increases, the bounce-height too will increase, but not always in direct proportion. The efficiency will decrease as the drop height is increased.
What is the amount of work done by the force of gravity when a stone of mass'm' is dropped from a multi - stroreyed building of height 'h'?
It's exactly the gravitational potential energy that the stone had, relativeto the ground, before it was dropped:M G H = (9.8) x (the stone's mass) x (the height of the building) joules
