How is the conservation of energy applied to an object in free fall from a height h to the ground?
In free fall, the object converts its potential energy at height h into kinetic energy as it falls. The conservation of energy principle states that the total energy (sum of potential and kinetic energy) of the object remains constant if we ignore factors like air resistance. Therefore, as the object falls from height h to the ground, its potential energy decreases while its kinetic energy increases, with the total mechanical energy remaining constant throughout the fall.

What is the maximum height hmax that an object will reach when its initial kinetic energy is converted into potential energy, according to the principle of conservation of energy?
The maximum height an object will reach when its initial kinetic energy is converted into potential energy is determined by the principle of conservation of energy. This height is known as the maximum height (hmax).
Is the height of a balls bounce affected by the height from which the ball i s dropped iv dv cv?
Yes, the height from which the ball is dropped will affect the height of its bounce. This relationship is known as the conservation of energy principle, where the potential energy of the ball at the initial drop height is converted into kinetic energy as it falls, leading to a bounce height determined by the conservation of energy equation.
What type of energy stored due to gravity and height above the ground?
Potential energy is the type of energy stored due to gravity and height above the ground. This energy is stored energy that has the potential to do work when an object is released from that height.
A bob of mass of 0.18 kilograms is released from a height of 45 meters above the ground level. What is the value of the kinetic energy gained by the bob at the ground level?
The kinetic energy gained by the bob at ground level can be calculated using the principle of conservation of energy. The potential energy at the initial height is converted into kinetic energy at ground level. Thus, the kinetic energy gained by the bob at ground level is equal to the initial potential energy, which is calculated as mgh, where m is the mass of the bob (0.18 kg), g is the acceleration due to gravity (9.8 m/s^2), and h is the height (45 meters). Substituting these values, we find the kinetic energy gained to be 79.38 Joules.
If a particle falls through a height its potential energy decreases. does this violate the law of conservation of energy explain why?
No, it does not violate the law of conservation of energy. When a particle falls, its potential energy is converted into kinetic energy. The total energy (potential + kinetic) remains constant, demonstrating the conservation of energy.

What increases with its height above the ground?
Potential Energy
What is the stored energy an object has as a result of its height above the ground called?
The stored energy an object has as a result of its height above the ground is called potential energy. This energy is related to the object's position in a gravitational field and is dependent on its mass and height above a reference point.
What best describes the object's energy as it falls trough the air from the stationary position at height x?
The potential energy it had at height x when it was not moving is equal to the kinetic energy it will have as it is falling. Why? Law of the Conservation of Energy. Energy before will equal energy after.
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 term describes the energy that is stored due to the height of an object from the ground?
Potential energy.
What is the maximum height hmax that an object will reach when applying conservation of energy?
When applying conservation of energy, the maximum height an object will reach can be calculated using the equation hmax (v2) / (2g), where v is the initial velocity of the object and g is the acceleration due to gravity.
What energies are possessed by a stone dropped from a height to the ground?
The stone initially possesses gravitational potential energy due to its height above the ground. As it falls, this potential energy is converted into kinetic energy associated with its motion. Upon impact with the ground, this kinetic energy transforms into thermal and sound energy, dissipating into the surroundings.
