it means that mass is a type of enrgy and it explains the very large amount of it in a unit of mass as it is multiplied by the speed of light
The total energy of an object is the sum of its kinetic energy (energy of motion) and its potential energy (energy of position). The combined total of kinetic and potential energy is known as the mechanical energy of the object.
The sum of the kinetic and potential energy of all the atoms in an object is equal to the total internal energy of the object. This internal energy is a measure of the microscopic energy associated with the motion and positions of the atoms within the object. Additionally, this internal energy contributes to the overall temperature and state of the object.
As the kinetic energy of an object increases, its potential energy decreases. This is because energy is transformed from potential to kinetic as an object gains speed or movement. The total mechanical energy of the object (the sum of kinetic and potential energy) remains constant if no external forces are acting on the object.
An object with the greatest amount of kinetic energy would be one that is both heavy and moving at a high speed. For example, a speeding bullet or a fast-moving train would carry a significant amount of kinetic energy due to their mass and velocity.
Although a slow-moving object may not have a high speed, it can still possess a significant amount of kinetic energy if it has a large mass. This is because kinetic energy depends not only on speed but also on the object's mass. In the case of a steamroller, its large mass contributes to its substantial kinetic energy even when moving slowly.

The total amount of energy before and after a transformation will be the same. Energy may pass from one object to another object, or be converted from one type of energy to another, but the total amount doesn't change.
The total amount of energy in an object is called energy, regardless of its form (heat, thermal, electrical, etc.).
The kinetic energy in an object is EK=mcV where V is the velocity, a vector.
It's internal energy if the object is microscopic and thermodynamic or mechanical energy if it's macroscopic.
The kinetic energy of an object is the energy it possesses due to its motion, while the potential energy is the energy stored in an object due to its position or state. The total energy of an object is the sum of its kinetic and potential energy.
The total amount of kinetic energy in the particles of an object is the sum of the kinetic energy of each individual particle. The kinetic energy of a single particle is given by the equation KE = 0.5 * m * v^2, where m is the mass of the particle and v is its velocity.
The amount of kinetic energy an object has depends on its mass and velocity. Kinetic energy is calculated using the formula KE = 0.5 * mass * velocity^2, which shows that both mass and velocity play a role in determining the total kinetic energy of an object.
An object has more thermal energy when it is hot, because thermal energy is the total kinetic energy of particles within the object. When the temperature of an object is higher, its particles move faster, resulting in a greater amount of thermal energy.
Thermal energy is the total energy of all the particles in an object, while temperature is a measure of the average kinetic energy of those particles. In simpler terms, thermal energy is the total amount of energy in an object, while temperature is a measure of how hot or cold it is.
Total energy of an isolated object is always same.
The thermal energy of an object is the total kinetic energy of its particles due to their motion and the temperature of the object. It is a measure of the object's internal energy and is directly related to its temperature.
