[math]1.5 kg \cdot 9.81 m/s^2 \cdot 2.5 m = 38.8[/math],, The value of the gravitational potential energy that is calculated using values in the above units is called the. That is why riding a bike up a steep hill is very hard, but when you are coming back down, you will not need to pedal at all - you are being powered by the gravitational potential energy that you stored when you rode up the hill. Gravity is the force of attraction that pulls objects together and causes things to fall to Earth. For example, a pen being held above a table has a higher gravitational potential than a pen sitting on the table. Gravitational potential energy, or GPE, is energy that is stored because of an object's position or height above Earth's surface. Another way gravitational potential energy helps us is by keeping earth and the other planets in orbit in our solar system around the Sun. flashcard set{{course.flashcardSetCoun > 1 ?
