The law of conservation of energy states that energy can neither be created nor destroyed, but can be converted from one form to another. This means that the total amount of energy in a system remains constant, regardless of any changes within the system.

Yes, bodies can get potential energy due to their position alone. Potential energy is the energy of an object due to its position relative to other objects, or due to its internal structure. For example, a book resting on a table has potential energy due to its position relative to the table, and a spring …
When the height varies the potential energy also varies . write down the situation which potential energy is varies. When a person jumps off a high platform, their potential energy decreases as they fall. When a rock is lifted up a mountain, its potential energy increases. When a roller coaster car climbs a hill, its …

The work-energy principle states that the work done by all forces acting on a particle is equal to the total change in the kinetic energy of the particle. In mathematical terms, this is expressed as: W = E_k_2 – E_k_1 where W is the work done on the particle, and E_k_1 and E_k_2 are the …
Potential energy is the energy stored in an object due to its position or configuration. This energy is released when the object is moved or changed in some way. Examples of potential energy include chemical energy, gravitational energy, elastic energy, and electrical energy.
Kinetic energy is the energy of motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. The kinetic energy of an object is directly proportional to the mass of the object and to the square of its velocity.
Chemical energy (e.g. fuel for cars, electricity for appliances) Light energy (e.g. from the sun, from light bulbs) Mechanical energy (e.g. from machines, from car engines) Heat energy (e.g. from burning fuel, from the sun) Electrical energy (e.g. from power plants, from batteries) Sound energy (e.g. from music, from voices) Nuclear energy (e.g. from nuclear …
No, the displacement is not necessarily opposite to the friction force. The direction of the displacement depends on the direction of the force applied to the object. If the force applied is in the same direction as the friction force, then the object will move in the same direction as the friction force. Conversely, if …
