PE = m g H = (2,500) x (9.8) x (200) = 4,900,000 joules, with respect to the ground level

What kind of energy is stored in a boulder on a mountainside?
It would be potential energy as long as the boulder stays still.
What type of energy does a boulder have as it sits on the top of a cliff 30 feet above the ground?
Gravitational potential energy as work is to be done to shift to such a height
A boulder falling through the air has what type of energy?
a boulder falling through the air still has some potential energy, but some of its potential energy has changed to kinetic energy...so it has both potential and kinetic!
When a boulder is rolling down a hill what energy is it losing?
Potential Energy
Dose a boulder rolling down a hill have potential energy true or false?
kinetic energy

What energy does a boulder have sitting on top of a mountain?
A rock on the top of a hill has potential energy. When it falls it has kinetic energy. You are probably in 6th grade to be learning this. :) Hope this helped you!

Potential energy is energy due to?
Potential energy is the energy that is waiting to be use. Such as when a boulder is sitting on top of a hill. The boulder has potential energy because it can be pushed down the hill. sara
What is one situation where gravitational potential energy might be dangerous?
It would be dangerous when a boulder is atop a cliff and falls down. The gravity would pull it down. Thus making the potential energy dangerous, for if it had no potential energy, it would not fall. Thus creating no need for the "Watch for falling rock" signs.
What was the initial transfer of energy that accelerated the boulder down the side of the mountain?
studyisland answer potential energy being converted into kinetic energy
Are all object at rest has a potential energy?
Potential energy is energy of position. If you talk about gravitational potential energy, an object higher up has more potential energy. It doesn't make sense to assign an "absolute value" to potential energy; you can only talk about a difference in potential energy. However, for purposes of calculation, you can arbitrarily assign a potential energy of zero for objects at a certain height - for example, the ground level, or an infinite distance from Earth.
A boulder is raised above the ground so that its potential energy relative to the ground is 200 J Then it is dropped What is its kinetic energy just before it hits the ground?
260 J. At the point of release, assuming the boulder is stationary before release, its potential energy is 260 J and its kinetic energy is zero. As it falls, the potential energy is converted into kinetic energy, but energy is neither gained nor lost, so at the point of contact with the ground its potential energy is zero and its kinetic energy is 260 J. If you want to be particularly critical, it could be argued that during the fall some energy is expended in displacing the air, but for a boulder the amount of energy expended would be a very small proportion of the total.
What are 5 types of potential energy?
Potential energy is often referred to as energy based on position but this is not totally true, for example electrical energy for instance has a position but it is still not potential but it is kinetic. This is because electrical energy is moving. Potential energy is actually referred to as energy that has the potential to move. For example, a boulder at the tip of a cliff. That boulder has the potential to move and fall off the cliff but it hasn't. Once it has however, its potential energy will be spent up turning the potential energy into kinetic. Types of Potential Energy: Nuclear: The Nucleus of an atom Chemical: Chemical bonds holding atoms together Elastic: A rubber band that is stretched out (I maybe wrong for this to be a type of potential energy)Thermal: Something heating up or cooling down.
