What is mechanical energy
Mechanical energy is a kind of energy created by the physical movement or rotation, revolution etc of anything.Since most of the movements done and energy created are done by machines, it is named as mechanical energy
Mechanical energy refers to the total energy possessed by an object due to its motion or position. It can be divided into two forms: kinetic energy and potential energy.
Kinetic energy refers to the energy of an object that is in motion. The formula to calculate kinetic energy is:
Kinetic energy = (1/2) * mass * velocity^2
where "mass" is the mass of the object in motion and "velocity" is its speed.
Potential energy, on the other hand, is the energy possessed by an object due to its position or height above a reference point. The most common types of potential energy are gravitational potential energy and elastic potential energy.
Gravitational potential energy is the energy an object possesses because it is located in a gravitational field. The formula to calculate gravitational potential energy is:
Gravitational potential energy = mass * gravitational acceleration * height
where "mass" is the mass of the object, "gravitational acceleration" is the acceleration due to gravity (which is approximately 9.8 m/s^2 on Earth), and "height" is the vertical distance of the object from a reference point.
Elastic potential energy is the energy stored in an object when it is compressed or stretched. The formula to calculate elastic potential energy is:
Elastic potential energy = (1/2) * spring constant * displacement^2
where "spring constant" is a measure of the stiffness of the spring and "displacement" is the distance the spring is compressed or stretched from its equilibrium position.
To determine the mechanical energy of an object, you need to calculate the sum of its kinetic energy and potential energy.
