A hammer falls off a roof top and strikes the ground with a certain kineic energy if it fell from a roof twice as tall how would it compare?

If it is initially at twice the height, it will have twice the potential energy (compared to the ground level); therefore, when it falls down, it will also have twice the kinetic energy (assuming air resistance can be ignored).

When an object is lifted 6 feet off the ground it gains a certain amount of potential energy If the same object is lifted 12 feet off the ground its potential energy is?
Double the first potential energy.
Use the law of conservation of energy to describe what happens to the potential energy of a rock when it is dropped from your hand and strikes the ground?
While falling, potential energy gets converted to kinetic energy (movement energy). Some gets lost to air resistance - that gets converted to heat. Once the rock hits the ground, most of the kinetic energy will be converted to heat.
As an object falls in free fall what energy is taking place?
Potential energy is converted to kinetic energy as the object gains speed. A small amount of that energy is converted in heat by air resistance and the remaining kinetic energy is normally converted to heat when it strikes the ground. Some energy may be converted into other forms of energy depending on impact speed.
What kind of energy gives off when a kid falls out of a tree?
Any object that is above ground level has potential energy. If the object falls down, the potential energy is converted to kinetic energy, i.e., the object will move at a certain speed.
A flowerpot falls from a ledge 50 m above the ground. compare the potential and kinetic energy when it is at 25 m above the ground to its original potential and kinetic energy?
After falling 25 meters, it has less potential energy, by an amount calculated with the formula mgh (mass x gravity x height). If you ignore air resistance, the kinetic energy will increase by the same amount.
Why do lighting strikes occur within a cloud rather than between clouds?
it does not have enough energy to reach the ground
When a ball falls and hit the ground how does the potencial energy of the ball compare to the ammmount of thermal energy produce?
Most of the potential energy will be converted to thermal energy in this case.
Does lightning travel from the sky to the ground or the ground to the sky?
What causes lighting??????? What causes lighting???????
Does lightining strike from the ground up?
lightining strikes from clouds not the ground
What to do when lightning strikes and your in a open ground?
RUN!

What is the kinetic energy of a 2.512 gram penny is dropped from a height of 16.76 m the instant it strikes the ground?
2.512 x 10 x 16.76 - 421.0112
What are the uses of the aircraft carrier today?
WWII-Naval battles (Fleet actions); troop support; strategic strikes Vietnam War-Strategic strikes against North Vietnam & close air strikes for ground troops Today-Strikes against precision targets/strikes in support of ground troops
When an object is lifted 12 feet off the ground it gains a certain amount of potential energy. If the same object is lifted 36 feet off the ground its potential energy is .?
3 times the original potential energy
What is happening when lightning strikes the ground?
it electricutes stuff
What stores enegry?
Stored energy is potential energy. Whether it's chemical potential(energy in chemical bonds) or gravitational potential energy(an object held at a certain height above the ground).
