The height of an object suspended in a uniform gravitational field gives the object an associated potential energy. This energy is described by
Potential Energy = m*g*h
where m represents the mass of the object, g represents the acceleration of the gravitational field, and h represents the height of the object relative the bottom of its trajectory.
When the object is released, it will tend to accelerate in the direction of the gravitational field, transforming its potential energy into kinetic energy. This is referred to as "free-fall." The kinetic energy can be described by
Kinetic Energy = 0.5*m*v2
where m represents the mass of the object and v represents the instantaneous velocity of the object.
During free-fall, energy is conserved so, the total energy of the system is constant and can be described as
Energytotal = Kinetic Energy + Potential Energy
E = 0.5*m*v2 + m*g*h
This is true at any instant during free-fall, so we can rewrite it to describe velocity in terms of height and we get
v = (2(E/m - g*h))1/2
To calculate the constant E, it is convenient to set the kinetic energy to zero (when velocity is zero) and the potential energy will be at its maximum. This occurs at the initial height. Here, the total energy is equal to the potential energy.
The height attained by an object projected up is directly proportional to the square of its initial velocity. So, if an object with initial velocity v attains a height h, then an object with initial velocity 2v will attain a height of 4 times h.
The height from which an object is dropped does not affect its average velocity. Average velocity depends on the overall displacement and time taken to achieve that displacement, regardless of the initial height of the object.
To measure the velocity of a falling object when the height is 2m, you can use the equation v=sqrt(2gh), where g is the acceleration due to gravity (approximately 9.81 m/s^2) and h is the height (2m). Plug in these values to calculate the velocity of the falling object when it reaches a height of 2m.
Velocity and height are related through the concept of kinetic and potential energy. As an object gains height, it typically loses velocity (kinetic energy) due to gravity acting against its upward motion. Conversely, as an object loses height, it gains velocity as its potential energy is converted back into kinetic energy.
The formula for calculating the height of an object in free fall based on its velocity is h v2 / 2g, where h is the height, v is the velocity, and g is the acceleration due to gravity.
That will depend not only on the escape velocity, but also - very importantly - on the object's speed.

To determine the maximum height reached by an object launched with a given initial velocity, you can use the formula for projectile motion. The maximum height is reached when the vertical velocity of the object becomes zero. This can be calculated using the equation: Maximum height (initial velocity squared) / (2 acceleration due to gravity) By plugging in the values of the initial velocity and the acceleration due to gravity (which is approximately 9.81 m/s2 on Earth), you can find the maximum height reached by the object.
The kinetic energy of an object depends on its mass and its velocity. The higher the mass or the velocity of the object, the greater its kinetic energy.
An object's kinetic energy depends on its mass and its velocity. As an object's mass or velocity increases, its kinetic energy will also increase.
