Is kinetic energy equal to MGH?

Consider an object of mass m is made to fall freely from a height h. At a start, the potential energy = mgh and kinetic energy = zero because its velocity is zero. Total energy of the object = mgh. As it falls, its potential energy will change into kinetic energy.

What happens if kinetic and potential energy are equal?

We take example of SHM. So, in SHM when displacement x= amplitude A divided by sqrt 2, kinetic and potential energies are same. Kinetic energy is equal to potential energy when height of the body is equal to square of velocity whole divided by 2times acceleration due to gravity . ie,h=v^2/2*g.

Why is kinetic and potential energy not equal?

Kinetic energy is the energy of movement or change. Potential energy is the energy a system has as a result of being able to undergo some change. As an object falls its potential energy decreases, while its kinetic energy increases. The decrease in potential energy is exactly equal to the increase in kinetic energy.

Why is not all potential energy converted into kinetic energy?

Potential energy isn’t transferrable and it depends on the height or distance and mass of the object. Kinetic energy can be transferred from one moving object to another (vibration and rotation) and is dependent on an object’s speed or velocity and mass. (It’s the falling hammer that has kinetic energy.)

Why is change in potential energy equal to negative work?

When an object falls due to the force of gravity the work is done by gravity on the object is in the direction of decreasing height and therefore the work is negative. As the object fall its potential energy decreases.

Why is work done MGH?

Thus mgh = 1/2mv^2, or negative change in PE equals positive change in KE (same as work gained). work done against conservative force gets stored as potential energy in object. Gravitational force is conservative force. So, Work done = mgh(gravitational potential energy).

Is F MGH dimensionally correct?

Answer Expert Verified it means formulas are dimensionally correct.
