What do you know about interconversion of energy of kinetic energy and potential energy of free falling bodies?

The potential energy decreases as the body falls while the kinetic energy increases.
P.E.=mass x gravity x height
The shorter the height the less potential energy there is
K.E.= 1/2 x mass x velocity^2
The velocity increases as the body falls and the bigger the velocity the more Kinetic Energy produced

∙ 13y agoThe kinetic energy of an object increases as its gravitational potential energy decreases.
For this, we use mgh for GPE and 1/2mv^2 for KE
This relationship can best be expressed as:
when something relinquishes all of its gravitational potential energy:
KE = GPE
when something relinquishes a part of its gravitational potential energy:
GPE = KE + GPE'
where GPE' = mg(h-h'), where h' is the distance the object has fallen

How can kinetic energy change into potential energy?
Yes, kinetic energy can change into potential energy. in order to do so the delta x would have to increase. for example if a skier were to go off a large jump, they would be using their kinetic energy to gain altitude and that would be increasing the potential energy, hope this helps, not being able to do so would be completely illogical
Distinguish between potential energy from kinetic energy?
There are many kinds of potential energy but only one kind of kinetic energy. Using gravitational energy as potential energy we get. mgh=1/2mv2 simplifying gives 2gh=v2
What type of energy can Kinetic energy can be converted to?
Yes it can. Potential Energy is "stored energy", while kinetic energy is the energy of an object in motion.Kinetic and Potential EnergyHistoryA roller coaster train going down hill represents merely a complex case as a body is descending an inclined plane. Newton's first two laws relate force and acceleration, which are key concepts in roller coaster physics. At amusement parks, Newton's laws can be applied to every ride. These rides range from 'The Swings' to The 'Hammer'. Newton was also one of the developers of calculus which is essential to analyzing falling bodies constrained on more complex paths than inclined planes. A roller coaster rider is in an gravitational field except with the Principle of Equivalence.Potential EnergyPotential energy is the same as stored energy. The "stored" energy is held within the gravitational field. When you lift a heavy object you exert energy which later will become kinetic energy when the object is dropped. A lift motor from a roller coaster exerts potential energy when lifting the train to the top of the hill. The higher the train is lifted by the motor the more potential energy is produced; thus, forming a greater amount if kinetic energy when the train is dropped. At the top of the hills the train has a huge amount of potential energy, but it has very little kinetic energy.Kinetic EnergyThe word "kinetic" is derived from the Greek word meaning to move, and the word "energy" is the ability to move. Thus, "kinetic energy" is the energy of motion --it's ability to do work. The faster the body moves the more kinetic energy is produced. The greater the mass and speed of an object the more kinetic energy there will be. As the train accelerates down the hill the potential energy is converted into kinetic energy. There is very little potential energy at the bottom of the hill, but there is a great amount of kinetic energy.TheoryWhen the train is at the top and bottom of the hill there is not any potential or kinetic energy being used at all. The train at the bottom of the first drop should have enough energy to get back up the height of the lift hill. The "Act of Faith" in riding these amazing rides which seems more of a phenomena that is only a theory. In practices, the train never could make it back up the hill because of dissipative forces. Friction and air resistance, and even possible mid-course breaks, are dissipative forces causing the theory to be changed but not destroyed. These forces make it impossible for the train to have enough energy to make it back up the lift hill's height. In the absence of the dissipative forces the potential and kinetic energies(mechanical energy) will remain the same. Since the mechanical energy is destroyed by the forces, the first hill is always the highest

How can you determined how much kinetic energy an object has?
Kinetic energy is possessed by moving bodies so that is easy. Potential energy comes in different forms - gravitational for instance due to height above the surface of the earth. Other forms like chemical, nuclear, elastic, are not so obvious, you need to know the properties of the material before it can be estimated.
What is energy possessed by moving or falling bodies?
kinetic energy
Does a microwave have kinetic or potential energy?
both. If moving we have kinetic. also have chemical energy stored in our bodies and that's potential energy. there is also physical potential energy stored in us if we are held up in the air with the possibility of falling.
Which friction slows down moving bodies kinetic or static?
Friction reduce the velocity, hence, it affect kinetic energy. The potential energy from static pressure is then drawn to maintain the velocity (transformation of potential -> kinetic energy). We then see the friction reduce the static pressure but actually, it affect kinetic first.
Define free falling bodies?

Why the velocities of falling bodies are not proportional to their weights?
Why the velocities of falling bodies are not proportional to their weights?
Who is the scientist that studied falling bodies?
Sir Isaac Newton and Galileo both studied the effects of gravity on falling bodies.
Why bodies are said to posses potential energy and transform in to kinetic energy while falling to earthsince the force driving is gravity how do bodies acquire energy?
In order to raise the body to a height from which it can fall, you have to apply upward force to it, opposing the downward force of gravity that most people call the body's "weight", and you have to keep applying that force until the body arrives at the height you want it to be at. All that force, multiplied by all that distance, is equal to a bunch of 'work', which is another word for 'energy'. The energy comes from muscles, or from electric motors, or from airfoils of some kind that remove the energy from wind, the energy gets stuffed into the body, and it resides there in the form of 'gravitational potential energy' until it falls. During the process of fallling, the potential energy that was stuffed into it by lifting it emerges in the form of kinetic energy.
Who discovered the law of falling bodies?
Galileo Galilei discovered the Law of Falling Bodies. Newton worked out the first equations. Einstein worked out better equations.
Why do the velocity of free falling bodies not change?
The velocity of free falling bodies do change However there are some exceptions like a free falling rain drop Please mention the case of which you want to know too
Where does the law of gravity operate?
Freely falling bodies
Why the earth exerts a force on falling bodies?

Do all the bodies have the same amount of kinetic energy?
Of course not. A battleship in motion has more kinetic energy than a housefly in motion has.
