When an object's total mechanical energy is NOT conserved?
When an object is subjected to external forces, such as friction or air resistance, its total mechanical energy is not conserved. Energy is converted into other forms, like heat or sound, causing a decrease in the object's mechanical energy. This results in a decrease in potential and kinetic energy as the object moves.
When only mechanical energy acts on an object what is conserved?
When only mechanical energy acts on an object, the total mechanical energy of the system is conserved. This means that the sum of the object's kinetic and potential energies remains constant, assuming no external forces or sources of energy are involved.
What is mechanical energy in science?
Mechanical energy is the sum of an object's kinetic energy (energy of motion) and potential energy (energy of position). It is the energy associated with the motion or position of an object due to forces acting on it. This energy can be transferred between different forms but is always conserved in a closed system.
What is the total energy of motion and position of an object?
If the object is moving, it's kinetic energy, if the object for instance is at the top of a slide it's potential energy.
What are the characteristics of mechanical energy?
Mechanical energy is the sum of kinetic and potential energy in a system. It is associated with motion and position of an object. Mechanical energy is conserved in the absence of non-conservative forces like friction.

When you throw a matter from a height why mechanical energy is not conserved?
When you throw matter from a height, mechanical energy is not conserved by you, but it is by the matter. You are exerting mechanical energy to throw the object, and the matter is conserving it by not having to do any work to move.
How is the energy of rolling object differ from the energy of the same object at rest?
When the object is rolling it has kinetic energy or KE and when the object is at rest it has potential energy or U. In this case both are mechanical energies and mechanical energy is conserved within a system meaning it is only transferred not gained or lost.
When is total mechanical energy conserved?
Total mechanical energy is conserved in a system when no external forces, such as friction or air resistance, are acting on the system. This often occurs in idealized situations like when an object is in free fall or when no energy is lost due to non-conservative forces.
What is mechanical energy in science?
Mechanical energy is the sum of an object's kinetic energy (energy of motion) and potential energy (energy of position). It is the energy associated with the motion or position of an object due to forces acting on it. This energy can be transferred between different forms but is always conserved in a closed system.

What is a mechanical energy?
Mechanical energy is the sum of potential energy and kinetic energy in a system. It represents the energy associated with the motion and position of an object. Potential energy is stored energy based on an object's position, while kinetic energy is the energy of motion. In a closed system, mechanical energy is conserved, meaning it remains constant if no external forces do work on the system.
Is it conservation of mechanical energy when skydivers drop in the air at a constant rate and why?
No. In free fall, where mechanical energy is conserved, the falling object would go faster and faster. In this case, to fall at a constant speed, mechanical energy is lost, due to friction.
What are the characteristics of mechanical energy?
Mechanical energy is the sum of kinetic and potential energy in a system. It is associated with motion and position of an object. Mechanical energy is conserved in the absence of non-conservative forces like friction.
What is mhecanical energy?
Mechanical energy is the sum of potential energy and kinetic energy in a system. Potential energy is the energy stored in an object due to its position, while kinetic energy is the energy an object possesses due to its motion. Total mechanical energy is conserved in a closed system, meaning it remains constant unless acted upon by an external force.
Mechanical energy is the sum of the kinetic and?
Potential energy of an object due to its motion and position with respect to gravity. It is conserved in a closed system where only conservative forces are at play.
