Yes. Potential energy is energy that has not yet been released. Kinetic energy is energy or an object already in motion.
Think of a ball 1 mile up in the air that begins to fall. After it has fallen 10 feet, releasing some, but not all of its potential energy, it has built up some kenetic energy as well from the motion of falling 10 feet, but still has 5270 feet worth of potential energy to go. What happens as the ball falls is that it gradually changes all of its potential energy into kinetic energy.co
Yes. If it is at whatever you define to be zero level for the purposes of calculating potential energy (often this will be ground level), and doesn't move, then it has zero (gravitational) potential energy, and zero kinetic energy.
Absolutely! The coexistence of both kinetic energy and potential energy is very common and more ubiquitous than you may think. Kinetic energy is energy associated with motion. If an object is moving, than it has kinetic energy. The faster the object moves, the higher the kinetic energy. Potential energy on the other hand is energy stored within the object. Potential energy can come in different forms including chemical and gravitational. In the case of gravitational potential energy, if an object is higher above the "zero" point of potential energy, the associated potential energy is greater.
Imagine the following scenario: You are at the top of a 100 meter tall building and have a ball in your hand. You chose the ground as your "zero" point of potential energy. You then drop the ball from rest causing it to plummet to the ground. Before you released it, ALL of the ball's energy was potential (because it was not moving and it was above the ground). At the moment just before the ball makes contact with the ground, all the ball's energy is kinetic. Somewhere in between there had to have been tradeoffs between potential and kinetic energies.
The period in between is where the interesting part lies. As the ball is free-falling, the gravitational potential energy of the ball is constantly being converted to kinetic energy; this happens because as long as the ball is not on the ground, gravity will continue to pull at it, causing it to move. As the velocity of the ball increases, so does the kinetic energy until the ball makes contact with the ground.
Therefore it is possible for an object to have both potential and kinetic energy.
Imagine you're on a roller coaster. Now imagine that you have already gone down the first hill. now a second smaller hill is coming up. When you are at the top of the hill you have kinetic energy going forward. But you also have potential energy going down because gravity is still trying to push you down.
Yes it can; if an object is at the top of a cliff at rest it has potential energy before falling to the bottom of the cliff where all energy is converted to kinetic, but when it is already moving, say after falling off a cliff halfway down, it has kinetic energy and potential energy ready to turn to kinetic at thee bottom of the cliff.
Yes, an object must be moving to have kinetic energy. If something is stationary at the top of a hill, it has potential energy, but no kinetic energy.
If an object's height is above the ground, and it is in motion, it has both potential and kinetic energy.
Yes. For example, a falling object has both.
Yes they can.
1) at the top of the swing, the swinging object has all potential energy and no kinetic energy (no speed at that moment) while at the bottom there is no potential energy but a maximum in kinetic energy, so that the swinging object is fastest at the bottom.
You are changing the object's gravitational potential energy. Gravitational potential energy is the energy due to position of the object above the Earth. This energy has the potential to be transformed into Kinetic Energy if the object falls.
When the object is moved, even a tiny bit.
Mechanical energy is the sum of potential energy and kinetic energy, the energy associated with the motion and position of an object. It is the energy that is generated by an object that is performing work or a job.
Kinetic energy is a form of energy that comes from motion. Therefore any moving object (that has a mass!) has kinetic energy. For kinetic energy to be produced, a force must act upon an object to give it an acceleration, to put it in motion. The simplest case is the conversion of potentiel energy to kinetic energy. When an object is far from its "normal" standing position (in this case the ground), it is said to have potential energy. When this object is attracted by the force of gravity, its potential energy is slowly converting into kinetic energy because the objet keeps on accelerating.
Potential energy is the energy contained in the position of an object, so object hanging on a tree would be potential energy.
Some of its potential energy changes to kinetic energy.
The name for the combination of the kinetic and potential energy of an object is heat.
potential energy is the energy that an object has stored up. kinetic energy is an object in motion. :) hi ppl :)))))))
The total kinetic and potential energy of the molecules of an object is thermal energy.
An object's potential energy doesn't depend on its speed. You can do anything you like with the object's speed, and it has no effect on potential energy.
The difference between potential and kinetic energy all comes down to a very simple property of the object. If an object is moving, then it has kinetic energy, or kinetic energy is the energy of movement. Potential energy is energy that is stored in an object and can be released under the right conditions.
Mechanical energy is defined as the SUM of potential energy plus kinetic energy. If all of its mechanical energy is potential energy, it follows that it has no kinetic energy.
Mechanical energy is kinetic or potential energy associated with the motion and position of an object.
Kinetic energy is the energy that an object has because of its motion. The energy depends on the speed and mass of the object.
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.
Kinetic energy is the energy of motion. Kinetic energy is stored in an object when you apply force to it, lifting it, for example. That energy stays in the object as potential energy until it is released when you drop the object.
