You will have a moment of inertia the same as the input in kg.m. To do so, multiply both sides of the equation by r and divide by m; v = F r / m = 3.6 5 / 2 = 9; Work out the square root of the previous outcome to get the velocity, v = 9 = 3 ft/s; We can also rewrite the result with a different unit. For example, the heavy ball of a demolition machine is storing energy when it is held at an elevated position. Where k is the Boltzmann constant and N A is the Avogadro's number. Even a slow-moving wrecking ball is capable of causing a lot of damage to another object, such as an empty house. Put the values: The standard unit of kinetic energy is the joule (J), while the imperial unit of kinetic energy (kE) is the foot-pound (ftlbf). You will have a value of KE in joules as it is a standard unit to represent the energy. Energy can exist in many forms. This is not coincidental! Gravitational potential energy is the energy stored in an object due to its vertical position or height. In this article, let us understand what energy is and the different types of energy in detail.
