Question

В чем различие кинетической и потенциальной энергии

Answer 1

Кинетическая энергия рассчитывается по формуле $E = \frac{mV^{2}}{2}$ и существует только тогда, когда тело движется со скоростью V
Потенциальная энергия рассчитывается по формуле $E = mgh$ и существует только тогда, когда тело находится на высоте h от поверхности Земли
Думаю, понятно, чем они отличаются :)

Answer 2

Difference between Kinetic and Potential Energy

Kinetic energy and potential energy are two forms of energy that objects can possess. They are different in terms of their definitions and the factors that contribute to them.

Kinetic Energy is the energy possessed by an object due to its motion. It depends on the mass of the object and its velocity. The formula for kinetic energy is:

Kinetic Energy (E_kin) = 1/2 * mass * velocity².

In this equation, the mass is measured in kilograms (kg) and the velocity is measured in meters per second (m/s). Kinetic energy is directly proportional to the mass of the object and the square of its velocity. This means that an object with a larger mass or a higher velocity will have a greater kinetic energy.

Potential Energy is the energy possessed by an object due to its position or state. It depends on the height of the object above a reference point and the force acting on it. There are different types of potential energy, such as gravitational potential energy and elastic potential energy.

- Gravitational Potential Energy is the energy possessed by an object due to its position in a gravitational field. It depends on the mass of the object, the acceleration due to gravity, and the height of the object above a reference point. The formula for gravitational potential energy is:

Gravitational Potential Energy (E_g) = mass * acceleration due to gravity * height.

In this equation, the mass is measured in kilograms (kg), the acceleration due to gravity is approximately 9.8 m/s², and the height is measured in meters (m). Gravitational potential energy is directly proportional to the mass of the object, the acceleration due to gravity, and the height.

- Elastic Potential Energy is the energy possessed by an object due to its deformation or compression. It depends on the spring constant of the object and the displacement from its equilibrium position. The formula for elastic potential energy is:

Elastic Potential Energy (E_e) = 1/2 * spring constant * displacement².

In this equation, the spring constant is measured in newtons per meter (N/m) and the displacement is measured in meters (m). Elastic potential energy is directly proportional to the spring constant and the square of the displacement.

To summarize, the main difference between kinetic energy and potential energy is that kinetic energy is associated with the motion of an object, while potential energy is associated with the position or state of an object. Kinetic energy depends on the mass and velocity of the object, while potential energy depends on factors such as height, mass, acceleration due to gravity, and spring constant
