Potential energy weight x height. The gravitational potential energy of an object near earths surface is due to its position in the mass earth system. 981 meters per second squared or more accurately 980665 ms 2 is widely accepted among scientists as a working average value for earths gravitational pull. Gravitational potential energy is due to the position of an object above earths surface. Pe potential energy j or kgm 2s 2. Potential energy mass x gravity x height. Find the potential energy when the mass is 12 with a height of 24 and acceleration due to gravity of 98.
M mass 12 g acceleration due to gravity 98 h height 24. E grav pe mgh. This is equivalent to its mass times the force of gravity g a defined constant of 98 ms 2 times the height of the object. G pe m x h height. For small height changes gravitational potential energy can be computed using where m is the mass in kg g is the local gravitational field 98 metres per second squared on earth h is the height above a reference level in metres and u is the energy in joules. Lets solve an example.
Pe m x g x h mass. Gravitational potential energy depends on an objects weight and its height above the ground gpe weight x height. Gravitational potential energy is due to the position of an object above earths surface. H pe m x g where m mass g acceleration of gravity h height gravitational acceleration of the earth is 98 msec2. Pe mgh pe 12 x 98 x 24 pe 28224. Potential energy e 0 0.
Gravitational potential energy depends on an objects weight and its height above the ground gpe weight x height. Potential energy m mass g acceleration due to gravity h height. The gravitational potential energy of an object is the stored energy that the object has by being at that height. Therefore the potential energy is 28224 joules j. Elasticpotential energy is due to an objects shape. Potential energy equations calculator science physics formulas.
Gravitational potential energy is the energy stored in an object as the result of its vertical position or height. M mass kg. The object has the potential to fall due to gravity. Potential energy e mass m acceleration of gravity g conversions. M pe g x h acceleration of gravity. The two examples above illustrate the two forms of potential energy to be discussed in this course gravitational potential energy and elastic potential energy.
Elasticpotential energy is due to an objects shape. The object has the potential to fall due to gravity. In this example a 3 kilogram mass at a height of 5 meters while acted on by earths gravity would have 14715 joules of potential energy pe 3kg 981 ms 2 5m 14715 j.
