What is the gravitational potential energy of a 5.0 kg object located 2.0 m above the ground?

Respuesta :

ghanem
potential energy= mgh (m:mass of the object g:acceleration due to gravity h:height)
potential energy=5*2*9.8=98 joule

The gravitational potential energy of a [tex]5.0 Kg[/tex] object located [tex]2.0 m[/tex] above the ground is [tex]98 J[/tex].

What is gravitational potential energy?

Gravitational potential energy is the energy possessed by an object due to a change in its position when it is present in a gravitational field.

[tex]U=m g h[/tex]

Where,

m = mass of the object

g = acceleration due to gravity

h = height

What are Examples of Gravitational Potential Energy?

Examples of Gravitational Potential Energy are

  • A book on a high bookshelf has higher potential energy than a book on the bottom shelf because it has farther to fall.
  • A child at the top of a slide.
  • A bird sitting on a tree branch
  • A plane flying overhead

There are different types of potential energy, such as elastic potential energy, chemical potential energy or gravitational potential energy. For example, elastic potential energy is energy stored in a spring. Chemical potential energy is the energy stored in chemical molecules.

The law of gravity states that the gravitational potential energy for an object must be equal to the amount of work done against gravity to move an object to a certain location. That means, gravitational potential energy depends both on height and acceleration due to gravity.

Given:

[tex]m = 5 Kg[/tex]

[tex]h = 2 m[/tex]

[tex]g = 9.8 m/s^{2}[/tex]

The gravitational potential energy is

[tex]U = m g h\\U = 5*9.8*2\\U = 98 J[/tex]
