10. Conservation of Energy

Gravitational potential energy is best defined as which of the following?

A uniform 2.00-m ladder of mass 9.00 kg is leaning against a vertical wall while making an angle of 53.0° with the floor. A worker pushes the ladder up against the wall until it is vertical. What is the increase in the gravitational potential energy of the ladder?

Which is the term for stored energy due to the interactions of objects in a $\mathrm{gravitational} \mathrm{field}$?

A space station orbits the sun at the same distance as the earth but on the opposite side of the sun. A small probe is fired away from the station. What minimum speed does the probe need to escape the solar system?

Which of the following formulas is used to find gravitational potential energy?

What is the form of energy stored in water held behind a dam called?

At which point on a roller coaster would a car have the greatest $gravitationalpotentialenergy$?

What happens to the $\mathrm{gravitational} \mathrm{potential} \mathrm{energy}$ of an object as it moves up a pyramid?

An eagle of mass $5$ kg flies from a height of $10$ m to a perch at $30$ m above the ground. How much gravitational potential energy did the eagle gain? (Use $g=9.8$ m/s$2^{}$)

Which factor affects $\mathrm{gravitational} \mathrm{potential} \mathrm{energy}$ but does not affect $\mathrm{elastic} \mathrm{potential} \mathrm{energy}$?

Which of the following best describes gravitational potential energy?

Which object has the most $\mathrm{gravitational} \mathrm{potential} \mathrm{energy}$?

At what point on the hill will the car have zero gravitational potential energy, assuming gravitational potential energy is defined as $U=mgh$ and the reference level ($h=0$) is chosen at the base of the hill?

Which of the following does not affect the gravitational potential energy of an object near Earth's surface?$U=mgh$
