The object has the potential to fall due to 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. Potential energy m mass g acceleration due to gravity h height. Pe potential energy j or kgm 2s 2. Elasticpotential energy is due to an objects shape. The object has the potential to fall due to gravity.

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. Gravitational potential energy depends on an objects weight and its height above the ground gpe weight x height. Elasticpotential energy is due to an objects shape. G pe m x h height. M mass 12 g acceleration due to gravity 98 h height 24. Gravitational potential energy depends on an objects weight and its height above the ground gpe weight x height.

M pe g x h acceleration of gravity. 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. Pe m x g x h mass. The change in gravitational potential energy δpe g is δpe g mgh with h being the increase in height and g the acceleration due to gravity. Gravitational potential energy is due to the position of an object above earths surface. M mass kg.

E grav pe mgh. 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. Pe mgh pe 12 x 98 x 24 pe 28224. The formula for calculating the potential energy. Potential energy e mass m acceleration of gravity g conversions. The gravitational potential energy of an object is the stored energy that the object has by being at that height.

Gravitational potential energy is due to the position of an object above earths surface. Potential energy e 0 0. Find the potential energy when the mass is 12 with a height of 24 and acceleration due to gravity of 98. Therefore the potential energy is 28224 joules j. Lets solve an example. Gravitational potential energy is the energy stored in an object as the result of its vertical position or height.

Potential energy equations calculator science physics formulas. H pe m x g where m mass g acceleration of gravity h height gravitational acceleration of the earth is 98 msec2. The gravitational potential energy of an object near earths surface is due to its position in the mass earth system. Potential energy mass x gravity x height. 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.
