PE = m G h = (150 x 9.8 x 50) = 73,500 joules, in the coordinate frame referenced to the base of the cliff.

Does a rock on the edge of a cliff contain kinetic energy?
No, because kinetic energy is the energy and object possesses because of its motion and its mass. Potential energy is the energy stored and held in readiness in an object. The rock has to be moving to have kinetic energy, but since the rock is just sitting on the edge of a cliff, it doesn't have kinetic, it has potential.
How does mass and height affect potential energy?
Increased mass and/or height increase potential energy.
Potential energy of the mass m?
Gravitational potential energy is calculated as mass x gravity x height.
Book on a shelf potential or kinetic energy?
Carry it up a cliff. ************************** Increase the height of the object or increase the mass.
Does an object have more potential energy the more mass it has?
Yes - gravitational potential energy is equal to mass x gravity x height.Yes - gravitational potential energy is equal to mass x gravity x height.Yes - gravitational potential energy is equal to mass x gravity x height.Yes - gravitational potential energy is equal to mass x gravity x height.
What name do you give to the energy that the car has on the edge of a cliff?
By virtue of its position on the top of the cliff it has "potential" energy. If it were to fall off the cliff this potential energy would be converted into "kinetic" energy (the energy in movement of a mass).
How does potential energy effect kintetic energy?
Think of an object falling from a cliff: Potential energy = mass x gravity x height. So a larger object falling from a higher cliff will start out with more potential energy. As it falls, it speeds up, converting its potential energy into kinetic energy. Kinetic energy = 1/2 x mass x velocity2. If it bounces, some of that KE is converted back into PE; otherwise it is lost as heat and sound (or in breaking things).

What is the mass of a book on a 2 meter high shelf with 20 joules of potential energy?
10
What will happen if you increase the mass of an object what will the potential energy do?
If you increase the mass of an object, the potential energy will increase.
How do the mass and height of an object affect the gravitational potential energy?
Apex Mass and height have the same effect on gravitational potential energy.
What do potential energy and kinetic energy have in common?
they have mass
Potential energy of the mass m?
Gravitational potential energy is calculated as mass x gravity x height.
How does tidal energy convert to potential energy?
Potential energy includes that of mass in a gravitational field. The water in a lake high in a mountain has potential energy which can be converted by a hydro electric generator when allowed to fall by gravity. Sea water retained at high tide can be used in the same way when the tide has receded

Does a man possess potential energy?
Potential energy can be calculated by the equation U ( which is the potential energy) = mgh, where m is hte mass, g is gravity, and h is the height of the object above the point where h=0 (often the ground). So, as long as h does not equal zero (imagine the man sandin on a cliff above sea leve, which is h=0) then he will have potential energy.
