Suppose a falling object loses 7J of potential energy. How much kinetic energy will it gain?

From what I understand:
PE - Potential Energy (mgh)
KE - Kinetic Energy (1/2 mv2)
If one dismisses the friction with air (conservation of energy), a loss of 7 joules for potential energy means a gain of 7 Joules in kinetic energy.

Is a falling ball potential or kinetic energy?
it is kinetic because it involves releasing the energy.
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!
What is the energy in an object about to fall?
the energy in an object about to fall is potential energy then kinetic energy because when the object is not falling, it has potential energy but when it's actually falling, it has kinetic energy.
What type of energy does a falling water?
potential and kinetic
What has both kinetic and potential energy?
A falling object.
Elastic energy is the total potential and kinetic energy in a system?
No. For example a falling stone is converting potential energy of gravitational attraction into kinetic energy, and there is no elastic energy.
What is energy from potenttial energy kinetic energy would be what?
A falling rock. In the air it has potential energy, as it falls it gets kinetic energy.
What has potntial energy that changes to kinetic?
A falling object changes from gravitational potential to kinetic.
What is the two forms of energy?
Kinetic energy (energy of motion) and potential energy (stored energy) A ball at the top of a building getting ready to be dropped has potential energy, but a ball falling has kinetic energy If the ball is at the top of the building, it has 100% potential and 0% kinetic and when it is halfway from top to bottom and falling it has 50% of each
What is an example of how potential energy can transform into kinetic energy?
A rock falling of a cliff.
What is an example of gravitational potential energy tranforming in kinetic energy?
A falling stone.
What form of energy is a falling rock?
That is a trick question, but I believe it is kinetic energy.
