In a closed system without external forces, the total mechanical energy (which is the sum of kinetic and potential energy) remains constant. Kinetic energy represents the energy of motion, while potential energy is associated with an object's position or state. The total energy of an object or system cannot exceed its initial energy without external work being done to increase it.

What energy can change from on form to another but cant be created or destroyed?
The energy that can change from one form to another but cannot be created or destroyed is known as "energy conservation." According to the law of conservation of energy, the total energy in a closed system remains constant over time, even as it may change forms such as kinetic, potential, thermal, or chemical energy.
What some examples of kinetic and potential energy?
Examples of kinetic energy include a moving car, a swinging pendulum, and a flying bird. Examples of potential energy include a stretched rubber band, a ball at the top of a hill, and a raised hammer.
What is gravitational energy-?
Gravitational potential energy is the kinetic energy that an object could gain if it was allowed to move through the entire gravitational potential in question. For example, if you climb a tower that is 100 feet above the Earth's surface and hold a ball, the ball will have potential energy as long as it remains at that height (in other words, as long as it remains at that potential). If the ball is dropped, the potential energy begins converting into kinetic as the ball falls through the 100 foot gravitational potential. When the ball is on the surface of the Earth, it no longer has any gravitational potential energy with respect to the Earth's surface. All of the energy converted into kinetic energy. When the ball actually hit the Earth, the kinetic energy was converted into heat and the ball stopped moving. That heat warmed the surrounding atmosphere a bit. No energy is ever lost, it just converts from one form to another.
Is potential energy the same as energy being conserved?
No, potential energy refers to the energy that an object possesses due to its position or configuration, while the conservation of energy is a principle stating that the total energy in a system remains constant over time. Conservation of energy implies that potential energy can be converted into other forms of energy, such as kinetic energy, and vice versa, but they are not the same concept.
What types of energy are used when blowing a whistle?
there is a little energy used, the point is you simply convert a wind energy into a sound energy. remember you cant create any kind of energy.
Why cant a substance have high kinetic energy and high potential energy?
Bcus when posesing knetic e is in motion,and it can n't b in motion and at d same time standing in rest
How can you make energy using waterfalls?
it cant make energy it is kinetic if it flows

What is is potential energy stored in?
Potential enery depends only on the position of the object. It cant be 'stored'.
How can energy be stored?
Energy can be stored in various forms such as chemical energy in batteries, potential energy in elevated objects, kinetic energy in moving objects, thermal energy in hot materials, and gravitational potential energy in raised weights. Different storage methods suit different energy needs and applications.
How can you find kinetic energy?
Kinetic energy can be calculated using the formula KE = 0.5 * m * v^2, where KE is the kinetic energy, m is the mass of the object, and v is the velocity of the object. This formula relates the kinetic energy of an object to its mass and velocity.
Why cant the kinetic energy of all the atoms in an object be measured?
because they are so small and objects contain so many of them, it is impossible to measure the kinetic energy of all the individual atoms
How does kinetic energy affect your life?
Kinetic energy is the energy an object possesses due to its motion. In daily life, kinetic energy plays a role in activities such as walking, driving a car, or playing sports. Understanding kinetic energy helps in calculating the speed and impact of moving objects, which is important for safety in various situations.
Is potential energy the same as energy being conserved?
No, potential energy refers to the energy that an object possesses due to its position or configuration, while the conservation of energy is a principle stating that the total energy in a system remains constant over time. Conservation of energy implies that potential energy can be converted into other forms of energy, such as kinetic energy, and vice versa, but they are not the same concept.
What is the difference between momentum and kinetic energy and why is it that kinetic energy can be changed in to other forms of energy but momentum cant?
Momentum is the product of an object's mass and velocity, while kinetic energy is the energy an object possesses due to its motion. Kinetic energy can be converted into other forms of energy, such as potential energy or thermal energy, because it is a form of energy associated with motion. Momentum, being a vector quantity, represents the object's motion and direction, so it is conserved in isolated systems and cannot be converted into other forms of energy.
