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).

If the hammer fell from a roof that is twice as tall, it would have four times the kinetic energy compared to when it fell from the original height. This is because the potential energy of the hammer is proportional to its height, so doubling the height results in quadrupling the potential energy, which is converted to kinetic energy as it falls.

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?
When the rock is dropped, it loses potential energy as it falls due to gravity. This potential energy is converted into kinetic energy, increasing the rock's speed. When the rock strikes the ground, all its potential energy is converted into sound and heat energy upon impact.
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?
When an object is lifted 6 feet off the ground, its potential energy is a certain value based on its height and mass. If the same object is then lifted 12 feet off the ground, its potential energy will be doubled compared to when it was lifted 6 feet. This is because potential energy is directly proportional to the height to which the object is lifted.
Why an object at rest on the ground has 0 Joules gravitational potential energy?
An object at rest on the ground has 0 Joules of gravitational potential energy because potential energy is calculated relative to a reference point, typically a certain height above the ground. When the object is on the ground, the height is considered to be zero, so there is no potential energy stored in the object relative to that reference point.
As an object falls in free fall what energy is taking place?
As an object falls in free fall, potential energy is being converted into kinetic energy. Initially, the object has gravitational potential energy due to its height, which is then converted into kinetic energy as it accelerates towards the ground.
What kind of energy gives off when a kid falls out of a tree?
When a kid falls out of a tree, the energy given off is kinetic energy in the form of motion as the child falls towards the ground. This kinetic energy is then transferred to other forms of energy upon impact, such as sound and potential energy from the child's position above the ground.
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 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?
The kinetic energy of the penny can be calculated using the formula: KE = 0.5 * m * v^2, where m is the mass and v is the velocity. First, calculate the velocity using the height dropped formula: v = sqrt(2 * g * h), where g is the acceleration due to gravity. Then, substitute the values to find the kinetic energy.
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).
